Best product, baked up with #1 service Purchased a filter on-line from a 'stockist', arrived without the frame to secure in the filter housing. Supplier didn't have another in stock, so contacted K&N UK by email explaining the issue and if I could buy the frame alone. Response within minutes with offer to provide required frame without charge, even though it was not their problem. Arrived within 48 hrs of being informed; great service. Product....have always fitted to EFI vehicles, especially if planning a re-map...6 bikes, 2 vans and 3 cars !

K&N Works !! Well, my Truck was not smooth until it warms up in winter my guy told me K&N would be helpful since I am into pool cleaning services sometimes I never have 10 Min to warmup but successfully after new filters, i feel the difference. 100% My Choice From Now!

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

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.

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.
