The Optima Search for the Ultimate Street Car began its final OUSCI qualifier at Auto Club Speedway in Fontana, California with a car show at K&N headquarters to welcome drivers and fans

The Ultimate Street Car Association (USCA) is a sanctioning body formed to create safe, fun and high profile national automotive events for street legal performance vehicles. The USCA, in association with several key sponsors, came together to promote nine nationwide Optima Search for the Ultimate Street Car events in 2015. All nine events serve as a qualifier for a highly coveted spot in the Optima Ultimate Street Car Invitational event held each November in Las Vegas, Nevada following the Specialty Equipment Market Association (SEMA) show.

In 2014, K&N Headquarters in Riverside, California played host as one of the stops along the Detroit Speed Road Rally and this in turn inspired the K&N Factory Car Show for 2015

Part of the Optima Search for the Ultimate Street Car challenge is the Detroit Speed Road Rally designed to test each car’s ability to function as a street legal performance vehicle. In 2014, K&N Headquarters in Riverside, California played host as one of the stops along the Detroit Speed Road Rally. Because the event was held on a Saturday night very few K&N employees, and almost no public audience, was able to witness the amount of time and ingenuity put into the cars competing in the Optima Search for the Ultimate Street Car series.

Despite the heat wave in Southern California, there were nearly 100 entries in the final USCA event, and many of those cars packed the K&N Filters Headquarters’ front parking lot

This fact inspired interested parties at K&N to become more involved in the USCA event for 2015. The majority of the Optima Search for the Ultimate Street Car competitors arrived a day or two before the USCA event in Fontana and they all love their cars. So why not host a car show at K&N Filters’ corporate headquarters and manufacturing facility in Riverside, California to welcome the competitors and share the experience with K&N employees? So began the first, hopefully, of many K&N Filters Factory Car shows designed to welcome Optima Search for the Ultimate Street Car competitors to Southern California.

K&N rolled out the red carpet for those competing in the 2015 Optima Search for the Ultimate Street Car event at Auto Club Speedway and shared the experience with K&N employees

It’s hard to complain about almost yearlong sunshine, however Southern California only experiences two seasons. Southern California, especially the areas inland from the coast, has a rainy season and a hot season with some mild periods in between. The week leading up to the Optima Search for the Ultimate Street Car event at Auto Club Speedway in Fontana, California began with rain; however the heat was once again nearing triple digits as the weekend approached. Despite the heat, there were nearly 100 entries in the final USCA event of the regular season, and many of those cars packed the K&N Headquarters’ front parking lot.

In addition to the car’s competing in the USCA event, many of the Optima Search for the Ultimate Street car series sponsors attended the car show at K&N. USCA sponsors in attendance at the K&N factory car show included: Optima Batteries, Falken Tire, Lingenfelter Performance Engineering, Wilwood Disc Brakes, and Detroit Speed & Engineering. Additional K&N partner companies, such as Clarion Audio, RideTech, Total Cost Involved, Go Rhino Products, 742 Marketing, and Hanro Studios were in attendance showing their support for the K&N factory car show. With so much support from within the performance aftermarket industry and from the K&N sponsored racers in attendance this event should be even better in 2016.

Fiesta owners in the market for a street legal boost in performance for the 2014 Ford Fiesta ST can get a K&N Performance short ram intake air intake system to fill that need

The Ford Fiesta is one of the best-selling global cars from the Ford Motor Company. In 2010 Ford released the sixth generation Fiesta and brought the Fiesta stateside for the first time since 1980. In 2013 Ford announced it was going to spice things up by adding a 1.6-liter EcoBoost turbocharged Fiesta ST to its lineup. The 2014 Ford Fiesta ST EcoBoost features overboost allowing the 1.6L turbocharged engine to make a claimed 197 horsepower when using premium unleaded fuel. A sub-compact car, like the 2014 Ford Fiesta, with 197 horsepower may seem like overkill, however the electronic traction, and stability control combined with race inspired suspension make this a fun car to drive.

Those owners should look no further than K&N Performance Air Intake System 57-2587. The 57-2587 Ford Fiesta ST air intake is expert-engineered and guaranteed to increase horsepower and torque. It replaces the restrictive factory system with a free-flowing, high-density polyethylene air intake tube to help minimize restriction, straighten, and increase airflow to the engine. Less restriction and more airflow translates into a boost in usable power throughout the engine’s RPM range.

Roto-molded air intake tubes, like the one used in the 2014 Ford Fiesta ST intake system, allow K&N designers to maximize use of tight spaces under the hood of modern cars

K&N’s RU-4960 reusable air filter is fitted to the inlet of the K&N roto-molded air intake tube to provide high airflow rates as well as outstanding engine protection. This K&N filter is washable and reusable and can go up to 100,000 miles between cleanings, depending on driving conditions. K&N air intake 57-2587, for the 2014 Ford Fiesta ST incorporates a heat shield which helps to deflect engine heat away from incoming air.

The K&N 2014 Ford Fiesta ST street legal performance air intake system is able to free up horsepower and torque lost to the Ford 1.6L EcoBoost engine due to air intake tract restriction.  On the dyno, when installed on a 2014 Ford Fiesta ST 1.6L, the K&N 57-2587 street legal Performance Air Intake System produced an estimated additional 7.21 horsepower at 5210 rpm and an impressive 10.07 pound-feet of torque at a low 3959 rpm. Additional testing was performed to determine if replacing the turbo charge pipe was necessary for power gains. It was determined that replacing this additional section of the air intake tube did not result in increased performance, and made installation much more difficult than necessary.

69-8704TP retains the stock 2013-2014 Lexus IS350 & GS350 air box to maintain factory connections, visual continuity, an earn an exemption order from the state of California

Street legal performance air intake system 69-8704TP from K&N Filters for the 2013-2014 Lexus IS350 & GS350 3.5L V6 luxury sedan models

Lexus was first introduced in 1989 as the luxury oriented division of the Toyota Motor Corporation. Lexus models, such as the 2013-2014 Lexus IS350 & GS350, benefit from Toyota engineering, and build quality but are very different from Toyota vehicles on the road. 2013-2014 Lexus IS350 & GS350 models are performance oriented luxury sedans designed to compete with other cars such as the BMW 5-series or Mercedes-Benz E-Class. K&N realizes that the typical luxury performance sedan owner is not only interested in touch-screen navigation, but also enjoys the rush of acceleration and the growl emitted by a performance-oriented engine. This is why K&N Filters has created a 50-state street legal air intake system 69-8704TP, for 2013-2014 Lexus IS350 & GS350 3.5L V6 models.

The 69-8704TP performance air intake system is a little different from the average cold air intake system. K&N engineers chose to retain the use of the 2013-2014 Lexus IS350, or GS350 stock air box when designing the 69-8704TP performance air intake system. Retaining the use of the stock air box allowed K&N engineers to increase performance while leaving all the stock emissions control equipment in place. This allowed K&N air intake 69-8704TP to earn an exemption order from the state of California for the 2013-2014 Lexus IS350 and GS350 models listed below.

K&N air intake 69-8704TP will fit the 2015 Lexus RC350, IS250, or IS350 but is not legal for sale or use on these models in California or other states adopting California emissions standards

A 2013 Lexus GS 350 gains an estimated 12.57 more street legal horsepower and 13.62 lb-ft of torque for better acceleration, drivability, and improved engine sound

K&N high-flow air filters provide less restriction than typical paper air filters, and because of this K&N air filter 33-2452, is able to reduce the restriction inherent to a stock air filter. K&N Air Filter 33-2452 is designed with K&N’s famous high-flow cotton gauze filter media to help increase airflow while also providing outstanding engine protection. 33-2452 is washable and reusable and can even go up to 50,000 miles between cleanings, depending on driving conditions. All of the design features of the 69-8704TP street legal performance air intake system work together to deliver a guaranteed street legal increase in horsepower and torque which will improve acceleration.

On the dyno, 69-8704TP produced an estimated additional 12.57 horsepower at 5,498 rpm and 13.62 pound-feet of torque at 4,376 rpm over the stock system. The 69-8704TP performance air intake system is an excellent upgrade for 2013-2014 Lexus IS350, and GS350 models. With simple to follow instructions and no need to make any other modifications to the vehicle, this intake can be installed in less than 90 minutes.

K&N backs the 69-8704TP Lexus air intake system with a 10-year/million mile limited warranty. Street legal performance air intake 69-8704TP is designed to fit and function properly on the 2013-2015 Lexus models listed below:

NASCAR K&N Pro Series East points Champ, and Sunoco rookie of the year, William Byron led the field to green before leading 57 laps at the Monster Mile and bringing home 9th place

The NASCAR K&N Pro Series East DriveSober125 at the Monster Mile in Dover, Delaware was originally scheduled to run on Friday, October 3, 2015. However, a tropical storm loomed on the horizon and made sure NASCAR officials had their work cut out for them to ensure one lucky driver got their chance to take home the 2015 NASCAR K&N Pro Series East Championship.

NASCAR K&N Pro Series East rookie Collin Cabre had never driven the Monster Mile in Dover, Delaware but got his first win in a car powered by an engine built in the K&N Engine Room at NTI

The green flag finally dropped on the NASCAR K&N Pro Series East DriveSober125 on Saturday October 4, 2015 at 12:30 pm. The DriveSober125 was the final race in the NASCAR K&N Pro Series East 2015 season. The drivers started the race without any practice or qualifying laps due to the weather. Many of the drivers were unsure of what to expect from their cars and the famed Monster Mile track in Dover, Delaware. NASCAR K&N Pro Series East points leader, and rookie of the year contender, William Byron led the field to green with no prior experience on the mile track. Byron led 57 laps in all and would bring his No. 9 Liberty University Chevrolet home in 9th place

21-year old Florida native Collin Cabre captured his first NASCAR K&N Pro Series East victory ever at the famed Monster Mile for the NASCAR Drive for Diversity team Rev Racing

After starting on the pole and leading 57 laps, Byron’s top ten finish earned him the 2015 NASCAR K&N Pro Series East Championship. William Byron also took home the Sunoco Rookie of the Year award; barely edging out teammate Dalton Sargeant. This was the third consecutive East series championship title for HScott Motorsports with Justin Marks following Ben Rhodes’ and Dylan Kwasneiwski’s championship winning seasons.

William Byron’s top ten finish at Dover earned him the 2015 NASCAR K&N Pro Series East Championship and Byron also took home the Sunoco Rookie of the Year award

Fellow Sunoco Rookie of the Year contender Collin Cabre was just one of many drivers to have never driven the Monster Mile in Dover, Delaware before the start of the DriveSober125. That didn’t stop Cabre from capturing his first NASCAR K&N Pro Series East victory for the NASCAR Drive for Diversity team Rev Racing. The 21-year old Florida native captured the win in his UTI/NTI No. 2 Toyota Camry. The winning car was powered by an engine built in the K&N Engine room at the NASCAR Technical Institute.

Airbags from Airlift Performance allow Vaughn Gittin Jr. to control the ride height based on the terrain. Kibbetech Offroad mated the airbags with King Shocks dual bypass shock absorbers in the front and triple bypass shock absorbers in the rear. The combined result is 12 inches of travel when fully lifted. Kibbetech also built a custom radius arm with panhard bar rear suspension. To handle all the power and abuse at the rear wheels, a Currie Enterprises full-floating F9 rear end was installed.

Runners up in the chase for the Championship were Scott Heckert, who finished 15 points behind Byron, and Austin Hill who finished 33 points back. Dalton Sargeant and Rico Abreu rounded out the top 5 in 2015 NASCAR K&N Pro Series East points. William Byron, along with other top finishing NASCAR K&N Pro Series East drivers, will be honored at the NASCAR Night of Champions Touring Awards at the Charlotte Convention Center/NASCAR Hall of Fame in Charlotte, North Carolina on Saturday, December 12, 2015.
