🔍 K&N Universal Clamp-On Air Intake Filter: High Performance Premium Filter for Enhanced Engine Efficiency: 4" Diameter, 5.5" Height, 1.125" Length: Washable & Durable: Round Tapered Shape: RG-1001RD Review

Used this filter to replace a worn out Specter filter that was catching on my wheels (truck with 24 tires) at low speed. This filter is shorter and worked great! K&N is always high quality.

I took this filter to add to my 1994 Mazda Miata intake project but the diameter was much larger than pictured and didn't fit properly, had to return. Also, it's a great looking filter and if I had the space I'd probably use it last. I chose another K&N filter that had the right fit.

Easy installation, comes with different hose adapters. I now have better throttle response compared to the AEM DryFlow filter I used. I used to have K&N filters and haven't had any problems with them. I've tried different brands but always come back to K&N. "If it ain't broke don't fix it!" look to K&N for a great and reliable filter. The only other brand I came close to was aFe and for a lot more money!

I used this to replace the cheap cone filter that came with the air intake I bought because I noticed that when I accelerated it felt like my car was being held back or restricted. So I settled on a brand that I know and trust that has a great range of cone filters. When I received the product it was very oily so I used a paper towel to wipe it off as I am concerned that the high oil content will clog my MAF. But after installing it, I noticed that my machine can now breathe easier and is more…

I placed an order and received the next day a brand new Genuine K&N Air Filter in a sealed blister pack with a K&N sticker! The air cleaner came pre-lubricated with all silicone adapter rings and clips included so it will fit my 2003 Infiniti Q45 (which has a 3.5" OEM air cleaner tube diameter). I definitely recommend this item! It's a reasonable price, especially considering it's a versatile model. A water resistant K&N "Dry Charger" case was also purchased separately to increase protection…

After removing my old filter, I noticed CAI (Cold Air Intake) after a few gas fills, while slowly noticing each time. That the car worked better on acceleration and had much better mpg after about 3-5 on each fill up. This is an old worn/used CAI filter that was a bit torn and didn't appear to have been changed in several years. This is when we talk about Scion tC 2007 with 123,000 mileage. After a while I changed the filter as it was bought second hand with about 103k mileage. I wanted to…

I will say that it worked perfectly. Because it's a genuine K&N filter, you can't beat the price. I have an aftermarket air intake system that requires this clip on style filter. My system has a 3.5" inlet and it worked great. Fits snug and well tightened. Filter diameter. If you want to know if this will work for your car, just open the hood of your car and measure the air intake diameter. If it is one of the three sizes mentioned in the description it will fit your car but remember this is a…

I drive a 2013 Ford Escape SE 1.6L ecoboost Okay, I'll start by saying I've wanted a K&N filter for a long time but couldn't get one. I finally had no choice but to get this as the paper filter in my car was so clogged that my car was going to the limit I felt sooooo sluggish even at 80mph and my gas mileage has dropped dramatically. (My fault for waiting so long 😓😬). My engine light came on because my (turbo)psi was higher than it should be due to a clogged filter. I don't think there is…
