Motorcycle Air Filters In The Nuclear Age

Motorcycle Air Filter Showdown: Which One Performs Best?

Ever wondered how different motorcycle air filters stack up? We’ve tested three types: paper, oiled foam, and oiled cloth. But that’s not all—we also put the Guglatech Matrix Filter to the test.

Using the highly dangerous (but totally worth it) radioactive BestRestium and magnesium silicate (talc), we’ve conducted these tests to bring you the most accurate results.

Watch Our Tests in Action

Part 1: We tested five air filters—K&N oiled foam, UNI oiled foam, BMW paper filter, and two Guglatech Matrix filters. See what particles passed through the filters and make an informed choice for your bike.

Part 2: We expanded the test to seven filters and added technical measurements, including vacuum levels and contamination weight on a scientific scale. This video gives you even more insights into which filter is best for your engine.

Part 3: In the final part of our testing series, we pushed the limits by using advanced contamination and measurement techniques to evaluate air filters. This video dives deep into the performance of each filter, revealing which ones let harmful particles pass through and which protect your engine the best. We also include a detailed analysis of the test data, providing you with the ultimate guide to choosing the right air filter for your motorcycle.

About the Author: David Petersen

I'm David Petersen, owner of BestRest Products. You can see my photo on the home page. I've been riding motorcycles for almost 60 years, and during that time I've had some wonderful adventure. In 2000 I started BestRest Products - our first product was a folding back rest, hence the name of the company. Over the years I kept designing and inventing gear. Today we have over 300 products in our store, and I created many of them. I ride a BMW R1200GS, a BMW F800GS, a Honda XR650R, and two KTM 450-EXCs. Plus I have a couple quads that I keep at a summer cabin. I spend most of my free time riding with my wife Judy. When not riding I'm answering the phones at BestRest or working in the shop on some project. I'm also the author of "How To Ride A Motorcycle Off Road", which is a free book you can download from the website.
