K&N レビュー 

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.

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!

I was interested in a cold air intake. My Boyfriend saw the one K&N had and said if I got it he would put it in. I placed the order and right away, (I knew something was off!) I'll make it short and sweet: Criminal enterprise! Or at least this is how I saw them as being potentially. I thought They had no intention of sending me their product. I didn't even receive an invoice! I called then wrote to their customer service (Again) this time I told them if I did not hear back from them I will be contacting my credit company and dispute the charges. They did respond, time stamped it an hour before I sent my email to them...Cute! Their email was so shady Google flagged it as ("Suspicious! Do not open links! This is from an outside source!") Thank Goodness for Google! K&N what happened to you? Don't do Business with these people. Have a nice day:) Today 8/17/23 I received an email stating my order has been shipped? (I have had a conversation with my card company about them.) I feel gaslighted by these people! "Standby" What would anyone expect acting as they do. So many others who have dealt with them have had the very same experience. This makes me very uncomfortable! Now, let us see if I actually get my full / correct order. Why do business this way.....Why? I'll update when I get my order, it is supposed to be here tomorrow? Hopefully in its complete form. 8/18/2023 I received my order and my friend installed it. Everything is fine. The only thing I have to say at this point is: (Work ON Your Customer Service Staff!) Or just change the way you do business? And read the comments below; the overwhelming number of nightmarish experiences! How much faith can one gain from reading these? Anyway It's in and it seems to work. This I'm grateful of.

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

zero customer service, they just don't care and don't respond!

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.

A terrible company to deal with. Ordered a product they took my money never shipped the item. I emailed to cancel the order no response. waited several days call into customer service. Waited more than an hour on the phone.

Ordered an item that I thought it was coming as a pair but it didn't . I returned the item unopened immediately , the company received it back and they have not issued my refund . I will be most likely have to dispute and go the hard way. Avoid by all means .

0-60 times are approx 1+ longer than standard. Hoping for faster. Parts missing from package. Do I have to clutter my garage with this junk. Nope. To the junk yard.
Called Customer service. They didn’t seem to know the theory behind cold air intakes.

Have always fitted a K&N to all my cars I recently bought a Nissan Micra 2012 and was averaging 53mpg now with the K&N fitted I'm averaging 63mpg on a run FANTASTIC I am barely touching the throttle now in 5th Gear Tickover now at 800RPM ( down from 1000) can't recommend it enough

They shipped me an intake system for my truck without a MAF adaptor. I contacted them as soon as I noticed and found their customer service center to be closed. Customer service has been short, borderline rude, and not very helpful or understanding of the urgency of the situation. I have to continue to call them to drive any progress. I sent an email Tuesday 3/21, received a vague email without any confirmation of any kind on what they sent on Thursday 3/22, and without any explanation or apology. I've yet to receive an apology. They said they'd overnight the part on Wednesday morning, and I've called several times since then for an ETA and the part has yet to ship as of 1:43 PM EST on 3/23/23. I would not order from this company again. They screwed up the order in the first place and then follow through on resolution has been poor at best.

I was going to buy a K&N air filter for my Mercedes CL500 but I tried calling their UK customer support (during business hours ) and it was closed. After further investigation and learning that the company has 62% 1 star ratings - I decided instead to "run" and have never looked back.

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 experience ever!! The customer service staff are extremely poor trained. I wanted a cold air intake for my 2013 mini. I called and had the staff confirm that I was ordering the right part which matched their yr make model search on website. They were to send but it never came, after 10 days I called they said it was in their warehouse. The said would send next day, but I asked asked again to confirm the part, told me I originally ordered wrong intake, ( they show 2 intakes for this model. He said he was sure and we changed order and new part came. Does not fit, I hope someone at k and n reads this because I’m going to be very mad when I call them back Monday.

Amazing customer service. The guy who helped me was very nice and helped me get the part i was looking for. He also told me it was completely under warranty and i didnt have to pay a dime. I was unaware of that and ready to pay for it. Also shipped out and was delivered super quick.

Ordered a Cold Air Intake system from these guys and they send me an incomplete set of parts in the box! Then I ask for a discount or something for the hassle and the waste of my time and I get told no! Never shopping here ever again!

Terrible co to deal with, Extremely controlling misleading and the filters are just crap the only thing that really sells them is the branding You’re better off with a paper filter and replacing it every couple of years
