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 !

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.

Costumer for life. I would like to say that they stand behind there product. I called them about a possible warranty on an air filter for my motorcycle. I purchased the bike used in 09 and the first thing I did was install a K&N air filter. It’s now 2024 and the filter media has started to deteriorate. I have always cleaned it every spring for the summer riding season. I called them and explained what was going on with the filter. They sent me a new one no questions asked. They didn’t even have me pay shipping. I was not expecting that. I will definitely be only running there filters for the rest of my life. You have definitely made a costumer for life.

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.

Ordered a filter which turned up… Ordered a filter which turned up looking worse than the one that came off the car!! Was told it must have got damaged on delivery to which I made them aware the packaging is not damaged in the slightest, and that it had left their warehouse damaged!! Placing the order went very smooth it was trying to get a response from anyone afterwards which proved to be difficult! However luckily I got through to a gentleman called Alan in the UK centre who sounded very stressed and mentioned also there is nobody manning the phones and how he’s trying to do it all!! I mean for a company that have been running this long that is pretty poor! Managed to get a replacement in the end but it was a task getting it!
