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.

Ordered a filter which turned up… Ordered a filter which turned up looking worse than the one that came off the car!! Was told it must have got damaged on delivery to which I made them aware the packaging is not damaged in the slightest, and that it had left their warehouse damaged!! Placing the order went very smooth it was trying to get a response from anyone afterwards which proved to be difficult! However luckily I got through to a gentleman called Alan in the UK centre who sounded very stressed and mentioned also there is nobody manning the phones and how he’s trying to do it all!! I mean for a company that have been running this long that is pretty poor! Managed to get a replacement in the end but it was a task getting it!

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!!

DONT EVER BUY FROM K&N WEBSITE! DONT EVER BUY FROM K&N WEBSITE!! If you want a product for your vehicle, buy from another site that will allow returns. K&N will ship it to you for free, but require you to pay for return shipping.
