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.

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...

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.

Terrible Support Amazing products, trusted brand, however their shipping logistics and product support are hands down terrible. Never order directly on their site, use a 3rd party like Amazon if you want to actually receive your products. Their support contact info on their site is not accurate and when you do contact support it seems they lack training and are a group of teenagers doing their “best” aka not helpful at all.
