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.

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 !

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!!

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.

Thanks K&NO... I bought a product on March 9th, 2024, it was a cool air intake for my chevy Colorado. a few days went by, and they emailed me saying my card failed? i tried again and of course it worked because my card never fails. its been a week now and still didn't get my product. 2 weeks later and my cool air intake comes in with the weld being upside down so im not a ble to even install it. i called them and they said they would ship me a new one and still no product it's been a month and a half. thank K&N...
