Have always fitted a K&N to all my cars I recently bought a Nissan Micra 2012 and was averaging 53mpg now with the K&N fitted I'm averaging 63mpg on a run FANTASTIC I am barely touching the throttle now in 5th Gear Tickover now at 800RPM ( down from 1000) can't recommend it enough

Well, my Truck was not smooth until it warms up in winter my guy told me K&N would be helpful since I am into pool cleaning services sometimes I never have 10 Min to warmup but successfully after new filters, i feel the difference. 100% My Choice From Now!

Amazing customer service. The guy who helped me was very nice and helped me get the part i was looking for. He also told me it was completely under warranty and i didnt have to pay a dime. I was unaware of that and ready to pay for it. Also shipped out and was delivered super quick.

I've had K&N filters in all my bikes and vehicles for a couple of decades. The fuel mileage increase was always there. The power increase was always evident in the bikes and a couple trucks. I just read a single star review and was surprised on his poor review until I read other reviews by him. He hates everything and gives poor reviews to all products and services. Great job K&N!

I ordered a K&N furnace filter on 2-4-22 at 9:30 a.m. and it arrived on 2-5-22 at 10 a.m., in Connecticut via FEDEX. Very fast delivery.
