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.

Really poor response really bad customer service Really poor response.. orderd some product’s didn’t get anything for a good 10 days then emailed them on the 3rd email they said ur order was lost ?!!! We were going to send u a new shipment til now noting really poor work for a big company it I regret buying online from them really bad

Worst company I ever dealt with spent… Worst company I ever dealt with spent 350 for Cold air I take, paid for expedited shipping never recieved my item. Customer service never answered me. I still don't have my item nor my money back. Will continue to post on social media how bad this company is

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.

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
