Information

The K&N R-0990 fits some Norton Commando 750, Norton Commando 850, Triumph 2500, and Triumph TR6 models. See vehicle applications for details. 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.

May 17, 2017 Part - R-0990
I ordered a set of R-0990 filters for my Triumph TR6 to improve the Injection systems air intake and am very pleased with the results, the car runs very well and the engine is much more responsive. I was very pleased with the help received on the telephone by each member of the staff in the office. The service was excellent and the order arrived the next day as promised. Thank You!
