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.

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.

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.

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!

The worst customer service ever The worst customer service ever. All they care is to get your money and when you need their support they won’t give the extra effort to have a happy customer. Will not do business with K&N ever.
