Mx5 Typhoon induction kit. £339.00 It arrived dented and chipped… it looks like a secondhand product. There is clearly zero quality control, an 8 year old could have packed it better!, I won’t be recommending them in a hurry!

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.

I paid 60 usd for overnight shipping to find out they sold me something they didn't have in stock. Terrible! Don't wase your time with them. And I still have to wait two weeks to be reimbursed.

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

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

Incredibly poor customer service as of late. I have used K&N products including oil filters, air filters, and intakes for over 10 years on various vehicles. Recently placed a new order, priority shipping. The order was delayed and never shipped after 5+ business days. After speaking with 3 different K&N reps through the process, I never received a single answer regarding why shipment was delayed. The only answer received that is outside the typical support jargon was "we dropped the ball, it will definitely ship tomorrow". This is certainly a reflection of current times in general, I find many businesses struggling with routine operations post-pandemic. K&N has not found a way to handle it, and no one there seems to care to improve the situation currently. I fear this may reflect quality control and assurance on their newest parts as well. My personal opinion is that customer service or support can make or break a deal, and quite quickly at that. Especially when multiple interactions seem to all give the same result.

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.
