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!

If you hate yourself If you hate yourself, and want to make your life more miserable buy their cold air intake products and weep as you find out that they neglected to include an EO decal required by law to accompany your air intake product, in order to get your vehicle smog checked. And then rip your hair out in pure frustration as you find out their customer service hotline is just a dead end loop leading to the same message robot with options extension number that don’t even work. Complete nightmare.

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 !

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.

GREAT CUSTOMER SERVICE! I ordered a Cold Air Intake from K&N alongside a complete filter set, I got the right filters but the wrong Intake. I'd sent 5 emails in total & hadn't got a response back so I was starting to get concerned, but they sent me an email apologizing for the delayed response and to let me know they shipped the correct one...and never asked me to return the wrong one they sent! HUGE SHOUT OUT TO CUSTOMER SUPPORT AT K&N, YOU'RE AWESOME!!
