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.

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.

Thieves They took our companies money to create a custom filter for our company, knowing that they wouldn't complete the project as they were going to stop doing this type of work, and they refused to refund even though they never provided the product. This company, and their associates, are a bunch of thieves.

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!

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.
