Customer Feedback

I have been driving my 2013 Ford Transit Connect for a couple of months. I have purchased KN filters for all of my previous vehicles. The filter in my Vuck ( best description of a van and a truck) has increaincreased the power in my Vuck. ..and only slightly in the mileage category. I find it important to be able to pass someone on a 2 lane and this filter did it all. If you have a Vuck I strongly recommend it.

Ordered an HP2011 oil filter and a VF2019 cabin filter for my 2011 Ford Edge Sport. I've had a K&N engine air filter installed since I bought the car. Order came UPS ground in three business days. Changed both today. Can't believe an oil filter could make such a difference in how much smoother my (3.7L V6) engine runs. I didn't know K&N even made a cabin filter until I searched online. Changing it took 5 minutes and I was shocked how cheaply made the OEM cabin filter was - and how filthy. The K&N cabin filter is built like the engine filter, with a big rubber gasket. I could immediately tell how much easier my A/C ran. Once again, K&N never fails to disappoint. Will be outfitting my other vehicle with all K&N (a 2016 Ford Escape) as soon as those products alerted online.

I have a '32 ford roadster and I took a '51 oil bath 2 Barrel air cleaner and made it for a four barrel, gutting the interior and then powder coating it. I had now a huge air clean less the element. I turned to K&N and used there 'size' selection page and after measuring exactly what I needed I was able to find the perfect K&N filter. Of course, I order the wrong one - but it got here in one day. Go figure, super fast. So I called and they were so kind to me, giving me a return number to put on the box and telling me to send the wrong one back to them. But I paid with PayPal, no problem, we will credit you. So I ordered the correct one, and got it in a day. Today I also see that Paypal credited me for what was owned. I never had to call and bug them. I am so impressed. They set the standard for how auto companies should deal with customers. Super happy guy and the finished product is really cool, I do admit.
