Customer Feedback      Be the first to review part E-1004

I recently experienced a failure in a component of my 57-2541 Cold Air Kit after 100,000 trouble free, fuel saving miles. The problem was easily diagnosed and repaired by me at home. I contacted Elzabeth Taylor in Customer Service who was extremely helpful and very understanding in regards to my situation. She instantly shipped me a the part to replace the part that I field fixed in my driveway. She requested that I take some photos and send them to her so that Research and Developement could take a look and make any adjustments if necessary. I was delighted to comply and sent them back to her later that evening. I have K&N Cold Air Kits in my 1999 Ford F-150 and my son's 2013 Chevy Sonic 1.4 Turbo. I have an air filter in my wife's 2012 Dodge Caravan. Your products have served us well and delivered the performance figures that you quoted. Actually, I got better than quoted performance on my 1999 F-150. I averaged over 1.5 mpg increase after the intallation. I will be purchasing a Chevy Silverado with a Duramax Diesel engine very soon. I am anxious to see what we can do with K&N products at that time. Keep up the good work and the great customer focused service.

My Honda Civic Hybrid is the third vehicle I have added a K&N filter. My Dodge Caravan picked up 2 MPG and more power, but my hybrid picked up 7 mpg which I thought was fantastic.

This is my second air filter for a Dodge Diesel truck, my first filter is in a 1990 Dodge Diesel and has about 400,000 miles on it, I am extremely pleased with my K & N air filter. This is the first time I have purchased from the on-line store and it was very easy to find the air filter for my 1997 Dodge diesel. It was out of stock when I ordered it on 9/20/13 and I received an email on 9/24/13 telling me my filter has been shipped. Thank You K & N Filters for your excellent service and updates on my order!!.
