K&N air filter for Honda Monkey 125 NO-GO
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
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: 1/10Product value: 1/10Professionalism of the company: 1/10Absolutely not worth it. Stay away — you can buy two identical filters elsewhere for the price of one on their website.

The Company say they have no hassle warranty
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.

Scam
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…
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!

I thought this was a bad idea.
I thought this was a good recommendation from my son who works at an auto parts store, however I was wrong. It took over 3 hours to clean, dry and replace. Then air intake was wrong due to not being able to get proper specs on oil replacement. Bad idea. Not recommended.

I'm not impressed with this product
I'm not impressed with this product. I ordered the kn 63-1568 for my 21 ram 5.7 and im not getting better throttle response and my pedal is not stiff like it was before,it feels like I'm driving a charger or challenger. I have to stomp the gas to see if Im getting results, it wasn't like that beforehand. I feel like ive lost hp and if that's the case in which most likely I'm sending it back. I dont feel anymore hp or torque then I already had its kind of a bummer bc its alot hype around this product but in my opinion it kinda sucks. Overrated product!

Terrible company.
Ordered on 12/19. Received shipping confirmation and tracking. Order did not move for 9 days. Contacted company. Received email 12/31 saying they never actually shipped item and could offer a refund. Today is 1/24. I have sent 5 emails and made 2 phone calls and still no refund. This company is pure trash. Nothing more than theft by deception.
