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.

Do not Buy form this company!!! Do not Buy form this company. They are currently holding $492 Dollars of my money after 2 returns after 3 months. I ordered a Cabin Filter and intake, They sent Air Filter and Intake (Same thing) Upon getting the intake it was made wrong (they admittded) and it did not fit. I sent all items back and have never received a refund. Their customer service while you can get them on the phone, they cant solve any problems.

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.

Skewed reviews shady practices I posted a 1 star review on their store for a poor fitment cabin filter that had to be curved and shoved making the filtration useless At 3x the cost oem. I get thr email confirmaion of my review and to my surprise my review was NOT posted on thir product site. It only has a handful of 5 star reviews only. This immediately made me lose trust in this company over thir shady practices and skewed reviews. I will never trust another one of their "high rated" products. Purchased many air intakes in tbe past. Will look elsewhere many options out there

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.
