Customer Feedback

I put a K&N in my 2004 Ford F150 FX4 right after I bought it. Nothing but great satisfaction with it. Averaged 22-24 mpg on the road. Not too shabby for a 4x4 with a 5.4ltr V8. The end of March, this year, I downsized to a 2016 Subaru Forester. Ordered a K&N the same day. Arrived in perfect condition and the car runs great. Have already noticed a pick up in power and better mpg than the factory states. I have nothing but great things to say about your product. Keep up the great work.

I can't compliment the kit more than the performance does. The kit brought new life to a 20 year old engine. The ease of assembly made it even more enjoyable. Thanks for a great product. Mike '96 Ford Bronco
