Product Description
The kit replaces your vehicle's restrictive factory air filter and air intake housing. K&N intake systems are designed to dramatically reduce intake restriction as they smooth and straighten air flow.

The filters on these kits are washable, reusable and easy to install with tools commonly available.

While servicing my 97 F250 Diesel I noticed the Air Filter housing was cracked at the base. This pretty much made it totally ineffective at removing any dust/dirt.Considering my options I purchased the K&N air filter kit to replace the stock system.Installation instructions were well written and easy to follow. Installation was completed in a couple of hours and I think I can even detect a little stronger acceleration.

My old filter housing was also cracked, and I have been wanting this set up almost, since my 1997 F-350 was new. WOW what a diferance this set has made. I live in the mountains 8,500 feet. Smoke from my tail pipe when pulling is almost gone, I can actualy here the turbo winding, and I do feel the engine is working much better.I should have bought this in 1997.Seller was very prompt, instructions were flawless. It took about an hour to install.
