Replacement K&N air filter, number KT-4511XD, is designed to fit inside the stock air filter box of many 2007-2016 KTM & Husky Motorcycles and includes a frame for even sealing

K&N is the official air and oil filter sponsor of the North American Hill Climb Association pro hill climb racer Brett Peterson of KTM Racing Malcolm Smith Motorsports Team Peterson Racing

Despite having some of the most advanced motocross and off-road motorcycles available, KTM, and its sister brand Husqvarna, equip these machines with an uninspiring air filter made from foam. 2007-2016 KTM 125-530 SX, SX-F, XC, XC-F, EXC and 2014-2015 Husqvarna 85-450 TC/TE/FC/FE owners can now equip their motocross, off-road, and enduro bikes with the high-flow air filter technology incorporated into K&N replacement air filter, part number KT-4511XD. The replacement K&N air filter for 2007-2016 KTM & Husky Motorcycles is designed to fit into the stock air filter box without any need for modifications. K&N replacement air filters are made with specially woven cotton gauze. Because cotton, by nature, is more breathable than foam, K&N replacement air filters can flow more air than a typical foam air filter. More air can result in increased acceleration, improved throttle response, and more power.

It would be false to assume that an increase in airflow with a K&N air filter comes at the expense of engine protection. K&N engineers placed filtration efficiency and dirt retention at the top of the priority list when developing air filter KT-4511XD for 2007-2016 KTM 125-530 SX, SX-F, XC, XC-F, EXC and 2014-2016 Husqvarna 85-450 TC/TE/FC/FE models. K&N knows that motocross, off-road, and enduro bikes will be raced in some of the most extreme conditions on the planet. This is why K&N paid extra special attention to the design of replacement K&N air filter KT-4511XD.

Installation of the K&N 2007-2016 KTM & Husqvarna reusable air filter is simple by using the included K&N sealing grease, the provided K&N air filter cage, and reusing the stock support strap

Chelsea Peterson, of KTM Racing Malcolm Smith Motorsports Team Peterson Racing, doubles as the 2014 NAHA Women’s Pro Class runner up and as a model for the 2015 K&N calendar

Perhaps the most important feature used in KT-4511XD is the additional layers, for a total of six, of our specially made cotton gauze sandwiched between wire mesh to form extra deep 1-1/4” pleats. Six layers of 1-1/4” deep pleated cotton filter media allows KT-4511XD to provide the performance and protection needed for motocross, off-road, and enduro riding. The K&N replacement air filter for 2007-2016 KTM & Husky Motorcycles utilizes an application specific support frame to ensure even pressure around the entire sealing surface and includes a tube of K&N sealing grease as an extra precaution.

KT-4511XD can be washed and made like new using one of the K&N Recharger air filter service kits. Recharger 99-5000 includes 12 fluid ounces of air filter cleaner and a 6.5 ounce aerosol bottle of air filter oil for quick and easy application. Recharger 99-5050 differs in that it includes an 8 ounce squeeze bottle of K&N filter oil for a more precise application. K&N air filter oil is key to trapping dirt and providing high levels of engine protection, yet it doesn’t have that annoying sticky texture like foam air filter oil. Larger versions of K&N Power Kleen and air filter oil are available on the air filter cleaning accessories page.

KT-4511XD for 2007-2016 KTM & Husky Motorcycles is backed by a one year limited warranty. This air filter is designed as a direct air filter cross reference for Husqvarna part number 54806516000, and KTM part number 77206015000. This replacement air filter is designed to provide increased performance, reusability, and long air filter service intervals without any need for modifications or tuning for the following KTM and Husqvarna motorcycles:

Gavin Gracyk, and the entire Team Faith Racing crew, rely on K&N air and oil filters for their Arenacross, Supercross, off-road, freestyle, and even personal watercraft racing efforts

K&N replacement diesel pickup fuel filter housings, where applicable, are made from high-strength carbon steel and powder coated for corrosion resistance

K&N diesel fuel filter, number PF-3000, will replace the factory or aftermarket diesel fuel filter used on most 2001-2013 Chevy Silverado HD and GMC Sierra HD 6.6L Duramax diesel trucks

A diesel fuel filter serves to screen out dirt and debris particles moving from a vehicle’s fuel tank, through the pump, and into the fuel injection system. A fuel filter is usually found in the fuel line after the fuel tank, but before the fuel pump. If the fuel were left unfiltered these fine particles, of rust, dirt, scale, and other foreign materials would cause rapid wear to the fuel pump and fuel injectors because of their rough grainy qualities. This could lead to eventual fuel pump or injector failure and a vehicle that will not run.

Replacing a diesel pickup’s fuel filter is part of routine vehicle maintenance. If a fuel filter is not replaced at the manufacturer’s recommended service interval it could become clogged and cause enough restriction in the fuel flow to reduce engine performance or struggle to maintain normal operation. Additionally, use and regular maintenance of a fuel filter can maintain factory performance and fuel economy. The less restriction found in the fuel system, and fewer contaminants, the more efficiently an engine can run.

The high-performance cellulose glass media used in the K&N diesel pickup replacement fuel filter line removes contaminants such as rust, dirt, scale and other foreign materials, providing excellent fuel system protection

K&N diesel fuel filter, number PF-4200, will replace the factory or aftermarket diesel fuel filter used on 2003 through 2009 Dodge Ram 2500 and 3500 pickups with a 5.9L Cummins diesel

K&N diesel pickup fuel filters are a direct factory replacement filter and offer your engine the protection and quality expected from the makers of the World’s Best Air Filter™. The high-performance cellulose glass media removes contaminants such as rust, dirt, scale and other foreign materials, providing excellent fuel system protection. K&N diesel pickup fuel filters are specifically designed to keep your engine running clean and smooth even in harsh conditions.

K&N diesel pickup fuel filters will replace a vehicle’s factory diesel fuel filter and are designed to meet or exceed OEM specifications. The fuel filter housing, where applicable, is made from high-strength carbon steel and powder coated for corrosion resistance. The high efficient, high capacity design is rated at 80 gallons per hour flow rates. The SAE J2044 compliant fuel connectors and rolled seams, where applicable, exceed OEM pressure requirements. These quality factory replacement K&N diesel pickup fuel filters are backed by a 90-day replacement warranty. K&N^® diesel pickup fuel filters deliver performance and confidence!

Not all diesel pickups are equipped with a replaceable fuel filter. Check your vehicle owner’s manual to see if your vehicle is equipped with a serviceable fuel filter and for the proper replacement intervals. To find a K&N diesel pickup replacement fuel filter for your vehicle, use the search by vehicle tool at knfilters.com.

The K&N diesel pickup fuel filter line is designed as a direct factory or aftermarket fuel filter cross reference and meets or exceeds factory design and performance

K&N diesel fuel filter, number PF-4000, will replace the factory or aftermarket diesel fuel filter used on 1998-2003 Ford Super Duty F-Series trucks equipped with a 7.3L Power Stroke Diesel V8 with a cap attached to the fuel filter

K&N air filter, HY-6510, is designed to fit into the stock air filter box of 2010-2013 Hyosung GT650 and GT650R motorcycles and will boost performance without the need for tuning

2010, 2011, 2012, and 2013 Hyosung GT650 as well as GT650R motorcycle owners have been chomping at the bit for the performance increase that can come from a K&N air filter. A replacement K&N High-Flow Performance Air Filter is designed to provide increased airflow, resulting in increased acceleration and throttle response while providing excellent filtration. Fuel management changes or additional modifications to the liquid cooled v-twin powered 2010, 2011, 2012, and 2013 Hyosung GT650 or GT650R motorcycles are not necessary to obtain increased performance.

Some might be worried that an increase in airflow comes at the expense of filtration efficiency and engine protection. K&N performs filtration efficiency testing following the ISO 5011 protocol to guarantee that our air filters will provide high airflow without sacrificing engine protection. Air filtration testing results are available online, and show that part number HY-6510 has better than 98% overall filtration efficiency rating.

Perhaps more exciting than the increased performance that comes with a replacement K&N High-Flow Performance Air Filter is that they are also a washable and reusable air filter. The ability to wash and reuse a K&N air filter means that it will pay for itself over time. A K&N washable air filter can be made like new using one of the K&N Recharger air filter service kits.

Covered by the famous K&N Million Mile Limited Warranty^®, and made in the USA, K&N HY-6510 performance air filter will be the last air filter your 2010, 2011, 2012, and 2013 Hyosung GT650 as well as GT650R motorcycle will ever need.

Each month listeners email Kurt Chase, host of The Automotive Edge Radio Show, to nominate their teacher and tell Kurt why they believe their teacher deserves Teacher of the Month

Kurt Chase has spent nearly thirty years in the automotive industry but around seven years ago he decided to use his experience to benefit others. Kurt started his career as a car salesman in the Dallas Fort Worth area in Texas. From there he quickly worked his way through the ranks until he was running car dealerships across Texas.

Each Teacher of the Month winner receives a K&N Filters automotive makeover including free K&N air, oil, and cabin filters, an oil change, and the winner will receive a gift certificate

Kurt woke up one day and felt a calling to do something more than making money for the car dealerships. No amount of money was worth the 80 hour work weeks and in turn missing the formative years of his children’s lives. Kurt began to provide seminars to provide the car buying public with information they could use to their advantage over the dealership. These seminars led to the formation of The Automotive Edge Radio Show.

In addition to helping hard working listeners to save money on car purchases and vehicle service, Kurt supports several philanthropic causes to better the lives of folks living in the Dallas Fort Worth area. One such program is the K&N Filters sponsored Teacher of the Month award. Each month listeners email the Automotive Edge to nominate their teacher and tell Kurt why they believe their teacher is deserving of the award.

Students and parents submit a nomination for Teacher of the Month to Kurt Chase at The Automotive Edge Radio show to express their appreciation for the hard working teachers out there

Each month’s winner receives a little special treatment by way of a K&N Filters automotive makeover including free K&N air filter, oil filter, and cabin filters as well as an oil change. As if that's not enough, the Teacher of the Month will also receive a gift certificate. Recently Kurt Chase presented Mrs. Gina Mitchell, a kindergarten teacher from Independence Elementary School, with the teacher of the month award.

Kurt Chase has three sons of his own and knows firsthand how much the teachers in the Dallas Fort Worth, Texas area sacrifice to provide a proper learning environment for students

Mrs. Mitchell was nominated because of her dedication to teaching and her involvement with parents. Mrs. Mitchell’s students love her and try to impress her. Mrs. Mitchell has implemented an award system in her classroom allowing well behaved children to select a toy at the end of the day. The nomination said Mrs. Mitchell keeps the parents informed of daily activities like picture day or overdue library books. She writes emails very early in the morning or very late at night. She works off the clock quite a bit. After school is dismissed Mrs. Mitchell can be found manning the cross walks as a crossing guard while saying good bye to the students and parents.

K&N is proud to be a sponsor of the Automotive Edge and the Teacher of the Month award. Kurt Chase is making a difference in the Dallas Fort Worth area by helping hundreds of people to save thousands of dollars as well as giving back to the community that has made him what he is today.

The K&N 2013-2016 Nissan Note and 2011-2016 Nissan Micra 1.2L supercharged L3 washable air filter is built with K&N’s high-flow cotton gauze filter media for a lifetime of reusability

K&N can be considered the authority in washable air filters, and the 2013-2016 Nissan Note and 2011-2016 Nissan Micra Performance air filter for 1.2L supercharged models has been engineered to fit in the stock air filter box without any need for modifications. Installation of a K&N Nissan Note or Micra performance air filter is simple, and can usually be completed in less than five minutes.

Filtration efficiency test results, following the ISO 5011 protocol with ISO coarse test dust, shows that the K&N air filter for Nissan Note and Micra 1.2L supercharged models is 98.68% efficient overall

Because cotton, by nature, is more breathable than paper, a K&N replacement washable air filter can flow more air than a typical paper automotive air filter. More air can result in increased performance and better acceleration. It would be false to assume that an increase in airflow with a K&N reusable air filter comes at the expense of filtration efficiency and engine protection. K&N performs filtration efficiency testing following the internationally recognized ISO 5011 protocol with ISO coarse test dust to guarantee that our air filters will provide high airflow without sacrificing engine protection. K&N replacement air filter 33-3027 was tested and showed a 98.68% overall filtration efficiency rating. Detailed filtration test results for this air filter are available for viewing.

A K&N replacement air filter is made with specially woven cotton gauze. Typical auto air filters are made of a restrictive paper material, and must be thrown away when dirty. The cotton gauze in a K&N Nissan Note or Micra 1.2L supercharged L3 performance air filter allows it to be washed again and again saving money over time and reducing waste. The K&N washable air filter for 2013-2016 Nissan Note and 2011-2016 Nissan Micra 1.2L supercharged L3 models can be washed and made like new using one of the K&N Recharger air filter service kits.

The K&N Performance air filter for 2013-2016 Nissan Note and 2011-2016 Nissan Micra models with the 1.2L supercharged L3 engine is backed by the K&N Million Mile Limited Warranty.
