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.

"Noticed a difference right away with this easy upgrade to a stock air filter. The car seemed to accelerate with a slight less hesitation. I'm sure the cost over time compared to a standard air filter will pay for itself. Excellent construction and if you aren't upgrading to the full CAI system this is a good alternative."

"I had to replace my K&N filter because my last one was stolen at a repair shop, thanks to the included Stop sign sticker that informs people not to throw the filter away because it’s a K&N. I have installed K&N filters on everything I drive for years and I’m not sure I have ever even noticed a power enhancement except on motorcycles. I do tend to note slight mileage improvements though, slight. I like the reusability and the maintenance interval. But don’t expect a 3 second drop on your ET’s and a few hundred extra horses just by dropping it in. It’s just a nice, good flowing, reusable filter."

"Installation is as easy as replacing any air filter. I immediately noticed the difference in off-the-line torque and my average gas mileage gage shows a 2 mpg increase in the city and 3 mpg on the highway. This costs the same as replacing a disposable air filter twice but this one lasts a lifetime and I found AutoAnything to be the lowest price (as usual). Jim"

Was it worth the cost of the new filter-absolutely!! K&N makes great products. Go for it!"

"After installing the K&N Air filter in less than 60 seconds, I went to fill up gasoline. Then i drove the car until it was empty, while measuring how many miles I would get. Surprisingly, I found this filter to add 50 extra miles per fill up! Also, the car smells better and I stopped sneezing with the windows closed. I only wish that K&N also made a Cabin Air Filter."

"This is the second car I've had a K&N air filter on. When I installed it on my Subaru Outback, there was an obvious increase in performance, and not a very obvious decrease in gas mileage. The reverse is true on the Maxima. I'm sure performance has increased, but the car already has so much torque that it's hard to tell. Gas mileage has decreased by 1-2 MPG under normal driving conditions. The bottom line is, get this product for power, not for fuel economy."
