K&N's Universal Air Filters are designed and manufactured for a wide variety of applications including racing vehicles, radio-controlled cars, generators, snowmobiles, tractors, and other applications. Regardless of the angle or offset diameter of the air intake, there is probably a K&N Universal air filter for your equipment. All filters are constructed with ultra-strong molded pliable rubber flanges which absorb vibration and allow for secure attachment and can also be stretched for up to 1/16 of an inch (1.5mm) to fit in-between sizes. K&N universal air filters are washable and reusable. When used as a replacement for the OEM air filter, modifications to the jetting may be required.

K&N R-1100 Universal Clamp-On Air Filter Product Reviews

I bought this filter for my 1954 NAA Ford Tractor to replace the oil bath filter. I have been using K&N filters since the 1970's and I will keep using them. I have had them on motorcycles, cars, trucks, and now on a tractor. The only reason I gave 4 Stars is because I want to see how it works on the NAA. Thank you Ron

Not 10 seconds after I installed this product on my 2014 Honda Grom, the crank immediately became locked. I am now awaiting for Woods Fun Center to tell me how many hundreds, if not thousands, of dollars this is going to cost to get my bike back up and running. No joke, this purchase may just be the worst decision I have ever made in my 34 years of existence on this earth. Sorry my feedback isnt more positive. I was really excited about this new addition to my bike. Trevor Lane
