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.

"K&N air filters are the best there is. Little pricey, but it boosts performance and is the last air filter you will ever buy. Too bad the air filter is so hard to reach on my Saab 9-5 (under the car!). Maybe that's all the more reason to get a filter you will never replace. Great product though."

"I've only had this in my '03 Mercedes ML350 for a week or so but fuel economy has improved (still checking but only filled up once last week to my normal 2Xs and approximately 500 miles). Filter was very easy to install and only took about 60 seconds (releasing fasteners, removing OEM filter, dropping in the new K&N, and securing the fasteners)."

"I installed my first K&N air filter in our 2001 Toyota Avalon, totalled in 2008. My second was the K&N 77 Series Metal Intake Kit I installed in my 2005 Toyota Tundra, which has improved power and gas mileage. My third K&N air filter is now in our 2004 Toyota Avalon, installed when it was due for a new air filter."

"I replaced the stock filter with a K&N filter about a month ago in my 05 S2000 and have consistantly gotten 1 to 2 mpg better mileage than with the stock filter. Nothing huge but with todays gas prices it's a welcome improvement. Installation was literally as easy as taking the top off the air box, pulling the stock filter out, and puttng the K&N filter in."

"I heard about this product and was skeptical but after installing it and then driving for the past two weeks i notice a dramatic difference that only the filter could have caused. this was installed in a new acquisition and all filters have been changed and now gas mileage on the highway is approaching 25 mpg - rough estimate. what a difference some clean filters, great tires, and suspension can make on performance. Highly recommend these for even the regular user. no more filters to buy at oil changes. the only filter your car will ever need."
