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 !

Really poor response really bad customer service Really poor response.. orderd some product’s didn’t get anything for a good 10 days then emailed them on the 3rd email they said ur order was lost ?!!! We were going to send u a new shipment til now noting really poor work for a big company it I regret buying online from them really bad

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.

Worst company I ever dealt with spent… Worst company I ever dealt with spent 350 for Cold air I take, paid for expedited shipping never recieved my item. Customer service never answered me. I still don't have my item nor my money back. Will continue to post on social media how bad this company is

Avoid K&N! Customer Service Sucks We ordered a K&N air filter for customers' Chevy Silverado, website showed it was in-stock at $69.00. We rec'd an email within an hour of order saying it was out of stock and no estimate of when back in stock. So we ATTEMPTED to cancel order, customer said he'ld get one on Amazon. K&N said order couldn't be cancelled and we'ld have to return product...??? Add insult to injury, Amazon ordered K&N filter was $48.00 and YES we did rec'd original filter weeks later. We returned it with a K&N return authorization and we are still waiting for a refund from these clowns 30+ days later. Advice: Shop around and DO NOT BUY DIRECT FROM K&N - their customer service is WORTHLESS!
