Fantastic immediate customer service even when the problem wasn’t with them and the delivery company. Sent with a different courier and received the following morning! Amazing item would defo recommend! I got the dry filter for my Mazda 3 bm!

My first order was sent with DHL who then lost the order. When I got in touch with K & N Eindhoven the response was instant, new order or refund? No questions or buts just classic service of the very best sort.
Two days later (Holland to Sweden) I had my filters, sent with Seabourne Express this time.
K & N Eindhoven are a company I recommend strongly to anybody who has need of anything they sell.

First got wrong filter in a right box and reseller didnt want to do anything about it so I thought that I contact KN directly and they were kind and replaced the misboxed filter! Great customer service!

I needed to qualify the exact KandN filter for my car.
Response was by return and I ordered the very same day.
Ordered on the 3rd of May and arrived / fitted today 6th May.
10 out of 10

Despite some issue with lack of product in warehouse and wait for delivery from US all went well and contact with support was smooth and kind. For sure will by again parts that my car will need

An excellent product and great customer service from Eindhoven when I needed to identify a non-standard fitment and return an item.

Ordered the wrong filter for my car (my fault, I ordered from my phone browser and didn't notice wrong product got selected) and only realized after the item arrived.
Contacted Support who were very prompt and helpful to arrange a Returns label and a full refund (I have now ordered the correct filter).
Very pleased with K&N!

many thanks to the team at K&N and their local logistics team. had a few issues with delivery with my local courier, and they solved it immediately. great service! thank you

This review is specifically for the K&N European/UK customer services. The service I received from K&N in Eindhoven on a warranty issue was excellent. Photographs were sent and the issue discussed and deemed defective, a replacement filter was sent out and case closed. Excellent customer service from the Eindhoven branch!

The company sent me a part which I was missing, they were very helpful and I would recommend them to anyone.

The Eindhoven Branch is one of the few in the Netherlands, where people actually do care about the client. I mean it.
They sent the order on time. The delivery company made a mess. So to fix things, I came in touch with the people from Eindhoven. A couple of emails, in a very polite manner, zero response the kind of "maybe, we don't know etc". No, they were clear and positive. That is the kind of help that you seek from a client support service. The sad part of the story is The product itself is quite robust, so I will not be purchasing anything from them any time soon at least.

I have purchased & fitted air panel filters, it has improved by making the car more responsive. Customer service was good via email & delivered on-time I would buy again

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.
