Description:

For more than 30 years, K&N cold air induction and cold air intake filters have been the choice in engine filtration. Designed to deliver virtually unrestricted flow to help your engine run stronger, cleaner and with greater fuel efficiency, K&N Air Filters are pre-oiled and ready for installation in your specific year, make and model.

The secret is in the filter medium – four to six sheets of pleated and oiled cotton-gauze are layered between two sheets of aluminum wire mesh. This tried-and-proven design traps dirt, dust and other harmful particles, while clean, power-enhancing air flows freely to your engine.

KN Air Filters require only a simple cleaning every 50,000 miles, and with no costly changes or services required, it saves you money in the long run. You’ll also help the environment in the long run by reducing the number of disposable air filters that wind up in our nation’s landfills. Street-legal in all 50 states, your K&N Drop In Filter is covered by a Million Mile Limited Warranty.

Notes:
Moss Warranty Act Statement

Thanks to the Magnuson Moss Warranty Act: US Code – Title 15, Chapter 50, Sections 2301-2312, your vehicle’s factory warranty is protected by law when you add aftermarket parts.

You really can't ask for more from an air filter

My '04 Infiniti M45 shifts faster and is a little more responsive after the K&N filter was dropped in. It took 10 seconds to change filters. The 340 hp of the v-8 sounds good and is a bit quicker, as well. Good job K&N!

Will soon own 3 K&Ns

I have the filter charger kit in my Chev. Tahoe and it has added 2 mpg city and highway. I just purchased a filter for my wifes Infinity Q45 and I will be ordering one in the next couple of days for my new Hyundai Sonata. I need to verify that the 2008 Sonata filter will fit my 2009.

Whoa!

I experienced an immediate increase in acceleration--talk about whiplash. My engine sounds stronger, and I'm sure I also have an increase in horsepower. I wil never purchase another disposable air filter for any of my vehicles.
