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

Wednesday, March 16, 2016 - Part R-1100
This is an important review for all the pulsar RS200 owners. Please, if you want to keep filters only go for R-1100 don't buy any other model like RC-1060 or any other filter model or company. If you want better performance R-1100 gives you that. Anyhow, the pickup has increased but I don't know about its top speed. After installing filter, once I do the speed test I will let you know in the review.

Woah! I changed the filter to a R-1100 and make no mistake it now roars more than ever. The performance was just great! Pick up increased and so did the top speed (a lil bit though). I put it to test and when travelling into hilly areas it performed really well. I was continuously hitting 100kph on those hilly curves and it didn't affect mileage at all (maybe it increased some not sure). Thanks K&N guys!
