Customer Feedback

Before, I thought you had to clean and oil the filter ever few hours like I had to on my Beta 4t Trials bike. Your rep said it would not require service for 30000 miles. I know Triumph air filters seem to stay pretty clean and the paper filters from the factory are still clean even after 5000 miles, but 30K miles? Hope he was right. The low restriction filter matches my airbox mods and computer perfectly.

Good fit and very good performance. Fit on my Triumph Tiger100 500cc 1970.

The air filter I bought from the K & N range made an unbelievable difference to my Land Rover Discovery in noticeable performance. (Hard to judge any fuel saving as the vehicle is always towing other vehicles out of trouble.) Buying the filter was very easy, no sucking air through the teeth or grunting, just a person who understood the product and easily identified the filter I needed.
