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

Great kit

I know I am keeping my cars for 3 to 4 years and I put about 35k a year and the reusable air filter especially in the dusty southwest is the way to go

best value and performance on the market!

It is the best filter on the market by any means. It have increase my gas mileage, the car also runs a lot smoother. It replaces at least 10 regular filters so this is definitely money well spend. It isn't that hard to clean either if you have access to pressure air or simply with a garden hose.
