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.

The replacement K&N air filter has noticeably improved the throttle response on our Ford Transit Connect.

Definitely better power, transmission stayed in overdrive going up over the Coronado Bay bridge. Before, it would down shift to hold it at 50 mph speed limit. On the first tank now with the New K&N filter, usingTop Tier gas as usual. Nice tight fit in the filter box. Can actually hear the air noise in the intake tube. Had bought a K&N filter for my 2004 Ford E250 at a parts house the same day. (Brand Name) didn't carry the Suzuki filter, that's why I ordered direct...thanks for very fast service. Paul
