The K&N reusable air filter for 2007-2016 Jeep Wrangler JK models with a 2.8-liter common-rail diesel engine is built with K&N’s special tight weave cotton gauze for extra protection

The third generation 2007-2016 Jeep Wrangler, commonly known as the Wrangler JK, can be equipped with an optional 2.8L common-rail diesel four-cylinder engine. The common rail diesel (CRD) engine is produced by VM Motori Cento in Ferrara, Italy and produces excellent torque ratings that rival the 3.6-liter Pentastar V6. However, the Jeep Wrangler 2.8L diesel L4 promises increased fuel efficiency and increased fuel range. Diesel engine technology is more commonly accepted outside of the United States, and as a result the Jeep Wrangler cannot be equipped with the 2.8L CRD engine in the U.S.

Filtration efficiency test results, following the internationally recognized ISO 5011 protocol with ISO coarse test dust, show that the 2007-2016 Jeep Wrangler diesel air filter is 98.95% efficient overall

Owners of 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015 and 2016 Jeep Wrangler JK 2.8L diesel models can equip their CRD powered SUV with a replacement diesel air filter from the authority in washable air filters, K&N. This reusable air filter is designed to fit into the stock air filter box of 2007-2016 Jeep Wrangler JK models with a 2.8-liter common-rail diesel engine 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 paper, a K&N replacement diesel air filter can flow more air than a typical paper air filter. More air can result in increased performance and better acceleration.

Diesel engine technology is more commonly accepted outside of the United States, and as a result the Jeep Wrangler JK cannot be equipped with the 2.8L CRD engine in the U.S.

It would be false to assume that an increase in airflow with a K&N diesel air filter comes at the expense of filtration efficiency and engine protection. K&N engineers place filtration efficiency and dirt retention as a priority when developing a diesel air filter. This diesel air filter uses design elements that go above and beyond our standard automotive air filters. K&N knows that a Jeep Wrangler JK diesel could be subjected to some of the most extreme conditions on the planet. This is why K&N used our special tight weave cotton gauze sandwiched between wire mesh to form extra deep 1-1/4” pleats. Four layers of 1-1/4” deep pleated tight-weave cotton filter media allows diesel air filter 33-5023 to outflow the stock air filter, hold a lot of dirt for long service intervals, and offer 98.95% overall filtration efficiency.

K&N performs filtration efficiency testing following the ISO 5011 protocol with ISO coarse test dust to guarantee that our air filters will provide high airflow without sacrificing engine protection. Calling this test dust coarse is almost absurd, as 22% of the dust is rated at 10 microns or less. To provide perspective, a human blood cell is typically between 6 and 8 microns across. Detailed filtration test results for diesel air filter 33-5023 are available for viewing.

Perhaps more exciting than the increased performance that comes with a K&N replacement diesel air filter is the fact 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. The K&N diesel air filter for 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015 and 2016 Jeep Wrangler JK 2.8L diesel models can be washed and made like new using one of the K&N Recharger air filter service kits. Please visit the K&N Air Filter Cleaner & Filter Cleaning Accessories page on KNfilters.com to view available air filter cleaner and oil products.

The K&N air filter for 2007-2016 Jeep Wrangler JK models with a 2.8-liter common-rail diesel engine is backed by the K&N Million Mile Limited Warranty.

The K&N reusable air filter for 2015-2016 Chrysler 200 2.4L or 3.6L

The second generation Chrysler 200 has been completely redesigned and utilizes a new Fiat based platform which, when combined with the 2.4L Tigershark L4 engine and a 9-speed automatic transmission, is able to provide an EPA estimated 36 highway MPG. Chrysler is calling the 2015 and 2016 200 the next generation mid-size sedan and hopes to compete with top sellers such as the Toyota Camry, Ford Fusion, and Honda Accord. Another advantage of the Fiat based U.S. Compact Wide vehicle platform is the ability to configure the 2015-2016 Chrysler 200 with all-wheel drive and an optional 295 horsepower 3.6L Pentastar V6. Seeing as the 2015-2016 Chrysler 200 boasts best in class available horsepower, an array of class exclusive features such as the 9-speed automatic transmission, and adaptive cruise control, rival automakers should consider the 2015-2016 Chrysler 200 as a serious threat.

K&N performs extensive testing to ensure K&N replacement air filters will stand the test of time and provide increased airflow without compromising filtration efficiency

No matter if 2015-2016 Chrysler 200 owners opt for the fuel efficient 2.4L Tigershark MultiAir II engine, or upgrade to the 3.6L Pentastar V6, a K&N replacement air filter can help provide upgraded performance and acceleration. K&N replacement air filters are made with cotton gauze filter media woven to K&N’s specifications. Because cotton, by nature, is more breathable than the paper air filter media used in the average automotive air filter, a K&N replacement air filter can provide an increase in airflow. More air and less restriction for the 2015-2016 Chrysler 200 mid-size sedan can result in a horsepower, torque, and acceleration upgrade.

The 2015-2016 Hyundai Genesis 5.0L V8 was equipped with dual air boxes due to its need to breathe, and K&N replacement air filters, number 33-5020 and 33-5021, will provide increased airflow

The word genesis means can mean origin or beginning. In the case of Hyundai Motors, the Hyundai Genesis Sedan signals the company’s beginning in the luxury car market. Another first for the Korean automaker is the Genesis Sedan’s optional 5.0L Tau GDI V8 engine. The 5.0L Tau GDI V8 features all aluminum construction, dual overhead camshafts, dual continuously variable valve timing, and gasoline direct injection. This technology packed V8 coupled with an over square bore and stroke makes for a potent and lively naturally aspirated 420 horsepower V8.

Filtration testing was performed on both 2015 Hyundai Genesis Sedan 5.0L replacement air filters to ensure the K&N high-flow replacement air filters will provide an increase in airflow, and long service intervals without sacrificing engine protection

Engine technologies aside, most Hyundai Genesis Sedan owners are attracted to this luxury car’s list of standard equipment and price tag. Loads of standard in-car technology, safety equipment, and ample amounts of power has put the Hyundai Genesis Sedan 5.0L trim level on par with cars from other automakers, such as the BMW 535i, Audi A6, and the Lexus GS350. However, the Hyundai Genesis Sedan has its competition beat with over 100 more horsepower and a price tag that is thousands of dollars less. Combine those benefits with the best warranty in the industry and the Hyundai Genesis Sedan 5.0L is the smart buyer’s choice.

A 420 horsepower V8 needs to breathe, and another thing Hyundai did right with the Genesis Sedan was to use a dual air filter box and dual air filter set up. However, from K&N’s perspective, equipping the 2015-2016 Hyundai Genesis Sedan 5.0L with ordinary disposable air filters was an error on Hyundai’s part. K&N replacement air filters are made with K&N’s specially woven cotton gauze filter media. Because cotton, by nature, is more breathable than the paper found in typical automotive air filters, a K&N replacement air filter can provide an increase in airflow. More air and less restriction for the 5.0L Tau GDI V8 powered Hyundai Genesis Sedan can result in a boost in horsepower, torque, and better acceleration.

A K&N replacement high-flow air filter is an easy to install performance upgrade for just about any car on the road. Most K&N replacement performance air filters can be installed in 5 minutes or less inside the stock air filter box and without any need for modifications. Since the 2015-2016 Hyundai Genesis Sedan 5.0L uses two air filters installation time should be under 10 minutes. K&N high-flow replacement air filter 33-5020 is designed as a direct air filter cross reference for the 2015-2016 Hyundai Genesis Sedan 5.0L right (passenger) side air filter box. K&N replacement performance air filter 33-5021 is designed to replace the disposable factory air filter inside the Hyundai Genesis Sedan 5.0L left (driver) side air box. Both of these air filters are expert engineered and made in the USA with an application specific design for excellent fit.

The pleated cotton gauze air filter media provides a large surface area, and because of a K&N air filter’s depth loading properties they are able to provide long service intervals. A K&N replacement air filter used in typical highway driving conditions can go up to 50,000 miles before service is required. When it does come time to service your K&N replacement air filter, the process can be done quickly and easily using one of the readily available K&N Recharger air filter service kits. The ability to wash and reuse a K&N washable air filter means that it will pay for itself over time.

K&N offers more piece of mind by performing filtration efficiency testing following the internationally recognized ISO 5011 protocol with ISO coarse test dust to ensure that our air filters will provide high airflow without sacrificing engine protection. Filtration testing on both 2015-2016 Hyundai Genesis Sedan 5.0L replacement air filters shows an overall filtration efficiency rating of over 98.5%. This means that although a K&N high-flow replacement air filter will provide an increase in airflow, and long service intervals, it does not do so at the expense of filtration efficiency or engine protection. K&N has made these filtration test results available on the product page for each of the 2015-2016 Hyundai Genesis Sedan 5.0L replacement air filters.

Cory Kruseman’s week in Tulsa, Oklahoma for the 2015 Chili Bowl Midget Nationals began with flash photography as the team revealed a new aerodynamic body design for the #21K car

In 1987 race organizers Emmet Hahn and Lanny Edwards organized a two-night race event in the Tulsa, Oklahoma metropolitan area on an indoor quarter-mile racetrack at the Tulsa Expo Raceway. The Midget Nationals received its name from the Chili Bowl Food Company who sponsored the first event nearly thirty years ago. Similar to the way a warm bowl of chili brings comfort on a cold day in the dead of winter, the Chili Bowl Midget Nationals brings heated racing to spectators and drivers two weeks after Christmas in a part of the United States often covered in snow.

The Chili Bowl Midget Nationals has grown exponentially and now takes place over the course of four nights with hundreds of racers hoping to qualify for the A-Main on Saturday night. Racers such as Ventura, California resident Cory Kruseman travel halfway across the country to try their luck in the Chili Bowl with hopes of taking home a Golden Driller trophy. The Golden Driller trophy takes its likeness from a 76 foot tall statue of an oil worker leaning on an oil derrick removed from a depleted oil field in Seminole, Oklahoma. The Golden Driller statue is Tulsa, Oklahoma’s most recognizable monument.

Cory Kruseman’s 2015 Chili Bowl Midget Nationals racing began with a third place finish in the Vacuworx Invitational Race of Champions which pits past winners against one another

Previous Chili Bowl winners include Tony Stewart, five-time winner Sammy Swindell, and Sammy’s son Kevin who has four wins to his name. The 2015 Chili Bowl Midget Nationals was the 29th annual running of the indoor midget race and the K&N sponsored team of Kruseman Motorsports left their home base in Ventura, California and traveled east with high hopes. Cory Kruseman is an accomplished sprint car and midget racer with two past Chili Bowl wins on his resume in 2000 and again in 2004. Having raced for most of his life, Cory also operates Cory Kruseman’s Sprint Car and Midget Driving School.

Cory began his week of racing in Tulsa, Oklahoma with the 7th annual Vacuworx Invitational Race of Champions (VIROC). For 2015 sixteen drivers made the cut for the VIROC event, with $2,500 on the line for whoever took the win. Cory Kruseman’s best VIROC finish, prior to the 2015 event, had been seventh place in 2014. This time around Cory would start from the fifth position and quickly work his way up to second place. A yellow flag late in the VIROC forced the field to restart. Cory Kruseman went to the bottom of the track in an attempt to take the lead from Sammy Swindell, however a bottleneck cost Cory a position and he would end up taking third behind Sammy and Bryan Clauson.

Cory Kruseman started the B Feature in 11th and within three laps he began to make his way forward in the pack, however, Cory’s luck began to run out, as his tire began to run out of air

Cory started B Feature 1 in the 11th position and within three laps he was beginning to make his way forward in the pack. However, Cory’s luck began to run out, as his right rear tire began to run out of air. Cory held onto the number 21K midget and finished B Feature 1. In the end Cory would rank 30th out of 326 drivers, which isn’t exactly how the two time Chili Bowl champion would have liked to ended up. However, Cory and the Kruseman Motorsports team won’t let their 2015 finish discourage them, and the team is already making plans for the 2016 Chili Bowl Midget Nationals.

In a daring pass just after the A-Main’s hallway point, Rico Abreu snuck past 2014 Chili Bowl champion Bryan Clauson. Kevin Swindell was involved in a crash early on in the race and subsequently had to make his way back toward the front. Kevin was able to move into second place, however he could not close in on Rico Abreu. Bryan Clauson made contact with Daryn Pittman on lap 39 and was sent to the back of the field. This allowed Damion Gardner to take home a third place finish in the 2015 Chili Bowl Midget Nationals.
