Customer Feedback

Be the first to review part E-9135
I have always used these filters but recently rebuilt my Ford Capri 3.0 ghia and took the oval filter off to put a paper hotrod style filter on, it looked the part but I wanted a K&N so came to this site ( and took just 5mins to order an insert and it got there the next day, I wish every part I've ordered online was this quick and easy.

The Air Filter Wrap fit perfectly on the Cold Air Intake I ordered and installed. The Cold Air Intake was a great choice, to enhance the performance of my Ford 6.4 liter Diesel truck.
