Description

For more than 30 years, K&N Filters have been the choice in engine filtration. The K&N filter delivers virtually unrestricted flow letting your engine run stronger, cleaner and with greater fuel efficiency.

The secret of the K&N filter is its filter medium. Four to six sheets of pleated and oiled cotton-gauze are layered between two sheets of aluminum wire mesh. This proven design stops dirt, dust and other harmful particles like no other filter, all while clean, power-enhancing air flows freely to your engine.

Just give it a simple cleaning every 50,000 miles and your K&N filter will last for the life of your vehicle. With no costly changes and services, your K&N filter will save you money. And, you'll be helping the environment by reducing the number of disposable air filters that end up in landfills.

Get increased power and acceleration, better fuel economy from a filter that lasts for 1,000,000 miles-get a K&N.

"I've used re-usable air filters for years, including in race cars, and K&N definitely makes the highest quality filter. They're more expensive than other filters, but they pay for themselves in the end."

"Overall, the K&N filter definitely makes a difference. The acceleration is better, especially at low rpms. The mileage showed a small improvement too... about 1/2 a mile per gallon. And the sound is just slightly more pronounced. So the K&N won't turn your car into a jet... but it will make a slight, but noticable, difference."

"What a pain this was, I tried repeatedly to fit it to no avail. Trying to get a flexible tube into an tight space is not a good design. It should have had a more solidly constructed mating collar than the rubber one that it comes with. Never again."

"I had a chance to drive a few miles and see how the K&N filter performed under various driving conditions: The vehicle being a 4 wheel drive truck, the engine is mainly designed for low-end torque. I notice a little more power in the mid range of the RPM scale. This is handy in passing situations. I gained about one (1) mpg increase in gas mileage; going from 19 mpg to about 20."

"I bought a new K&N filter after reading reviews on increased gas mileage. After checking several sights, autoanything had the best price. After I installed the filter I immediately noticed the increase in power and ease of the engine revving. I track my mileage and was getting 17.5 to 18 in the city. I have gotten 18.5 and 19 in the two fill-ups since. I love the filter and would recommend them to anyone who wants less maintenance, and to save money on fuel and filters.

"I bought this filter after installing one in my motorcycle & getting positive results. The first tank has returned a 15% increase in fuel mileage & the car requires less throttle especially while cruising. I plan to monitor for dirt downstream of the filter because I've been reading some not-to-flattering reviews on the K&N filters"
