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.

Thieves They took our companies money to create a custom filter for our company, knowing that they wouldn't complete the project as they were going to stop doing this type of work, and they refused to refund even though they never provided the product. This company, and their associates, are a bunch of thieves.

Do not Buy form this company!!! Do not Buy form this company. They are currently holding $492 Dollars of my money after 2 returns after 3 months. I ordered a Cabin Filter and intake, They sent Air Filter and Intake (Same thing) Upon getting the intake it was made wrong (they admittded) and it did not fit. I sent all items back and have never received a refund. Their customer service while you can get them on the phone, they cant solve any problems.

Faulty product and ZERO customer service Spent £420 on an induction kit for it to be faulty with a huge air leak in the piping. Contacted them via email 4 times to have zero response. Contacted on Twitter only to have my tweet deleted and also contacted on Facebook only to have them read the message and not reply. Absolutely disgusting service and I am now going to make a chargeback with my bank to get a refund.

Best product, baked up with #1 service Purchased a filter on-line from a 'stockist', arrived without the frame to secure in the filter housing. Supplier didn't have another in stock, so contacted K&N UK by email explaining the issue and if I could buy the frame alone. Response within minutes with offer to provide required frame without charge, even though it was not their problem. Arrived within 48 hrs of being informed; great service. Product....have always fitted to EFI vehicles, especially if planning a re-map...6 bikes, 2 vans and 3 cars !
