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.

Cold air induction 6th gen camaro Bought a cold air induction for my 2023 camaro 2ss. The kit is nice, but there was a part missing, and the instructions and video show removing the sound tube, which the 2ss does not have. The 20 & 50 torx head they tell you is needed, is not. Waste of money there.

Purchased a K & N oil filter Purchased a K & N oil filter, when ready to fit it got conflicting reports about if it would fit or not. Emailed K & N 10 times and no response. Avoid this company at all costs, most appalling company I have ever had the misfortune of dealing with. What's the use of having a so called "customer service" email if there is never any reply. Just amazed

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.

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.
