Purchased a K & N oil filter Purchased a K & N oil filter, when ready to fit it got conflicting reports about if it would fit or not. Emailed K & N 10 times and no response. Avoid this company at all costs, most appalling company I have ever had the misfortune of dealing with. What's the use of having a so called "customer service" email if there is never any reply. Just amazed

Costumer for life. I would like to say that they stand behind there product. I called them about a possible warranty on an air filter for my motorcycle. I purchased the bike used in 09 and the first thing I did was install a K&N air filter. It’s now 2024 and the filter media has started to deteriorate. I have always cleaned it every spring for the summer riding season. I called them and explained what was going on with the filter. They sent me a new one no questions asked. They didn’t even have me pay shipping. I was not expecting that. I will definitely be only running there filters for the rest of my life. You have definitely made a costumer for life.

Wrong filter Bought a filter for my Z4. It was the wrong type and size. Returned it as requested by the support. A month later no refund. Avoid buying stuff from their official website. I have already disputed the transaction with PayPal and am waiting for a resolution. I did email the support but no response yet.

K&N Works !! 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!

The worst customer service ever The worst customer service ever. All they care is to get your money and when you need their support they won’t give the extra effort to have a happy customer. Will not do business with K&N ever.
