K&NReviews of knfilters.com

Wait 4 weeks for a delivery and the product finder on website sent me to the wrong item that doesn’t fit my motorcycle. Really disappointed don’t recommend the service are really bad. Just received my package after sending several emails complaining about my order and the customer service asked sorry about the delay. Really disappointed with the service.

I just purchased a K&N air filter for my 2024 Honda Monkey 125. Very disappointed with the overall fabrication quality. A lot of leftover plastic extrusion that I had to manually removed around the inner portion of the filter that was loosely attached. Also a few metal wires that were sticking out of the filter so I had to remove/cut these metal wires. As for the plastic leftover from the injection process I had to clean all this up. Lose enough that they would had been sucked into the engine. (This plastic was on the inboard Side of the intake.) There is a handle/frame on this particular filter and it broke even before I installed it. I have purchased K&N in the past and had no issues. However the build quality and QC on this particular filter was really really poor. Feb. 16th 2026. I still need to run the bike with this filter , hopefully it will perform as it should. But not a happy customer especially since these filters are expensive.

DO NOT GET A K&N AIR INTAKE! it is not worth the money! you will regret it. You may have trouble with the MAS, Throttle Body, and it may mess up your cars computer even if you reset it. Waste of money. My car isn’t working properly because of it.

This has been one of the worst experiences I’ve ever had with a company. I will never again overpay for an air filter that is literally 50% cheaper anywhere else compared to their official website. I spent 104€ on an air filter that costs 66 USD, and I honestly have no words for their completely unresponsive customer support. I contacted them before the order was even processed and asked to cancel it. They ignored my request. A few days later, instead of responding, they simply sent me a notification that my order had been shipped — exactly what I asked them not to do. I work in a company that sells products to clients as well, and when someone requests a cancellation and refund, we take it seriously and make sure we do not ship an unwanted product. The fact that they refused to acknowledge my request is extremely unprofessional. When the package finally arrived at my local post office, the box was opened, unsealed, and damaged. Nothing was missing, but it doesn’t change the fact that the condition of the packaging made the whole situation feel even more careless and disappointing. Customer support: 1/10 Product value: 1/10 Professionalism of the company: 1/10 Absolutely not worth it. Stay away — you can buy two identical filters elsewhere for the price of one on their website.

must be the slowest delivery possible?

The Company say they have warranties on their product. I purchased my cold air intake system on Amazon four years ago. I have a leak on the pipe. When I contacted Amazon. They said they couldn’t help me. I asked them to reach out to the vendor for me. They said they couldn’t reach out to the vendor for me. They said I had to do it all on my own. I sent K and N an email. They never responded. I finally called their numbers and then they finally sent me an email that I could respond to with all my information after responding with all my information. They’re no hassle warranty. They told me didn’t cover my vehicle. I’m the end user, I bought the item on Amazon I entered my vehicle information, and it says it’s a perfect fit for my vehicle. And now the filter, Company, K and N says that that system that Perfectly Inside. My engine wasn’t made for my vehicle.

Marketing scam. Doesn’t increase hp or does anything. I lost hp car became sluggish. Rough idle followed. Oil became almost black quickly. If you have a stock car don’t buy this because you can’t fit more air in the combustion chamber just like no matter how much air is in the atmosphere you can’t possibly fit more in your lungs. Every thing has maximum capacity

I called the customer service number Wednesday 5/14/25 about 4pm and Katherine answered the line. I have never had a warranty exchange made so easy on any product I've ever had! I've used k&n products since I started driving 22 years ago and this was the first issie I've had, and because of Katherine's help, service, and professionalism, I will continue to use k&n more for the service than any other reason!
