As we all know, keeping the air filter on a dirt bike clean and sealed properly is critical to engine life. If dirt gets through the filter, it’s never a good thing. On a four stroke, sand and dirt that gets by the filter will quickly wear out an expensive valve train and cause hard starting and poor performance. On a two stroke, sand and dirt will destroy the piston and cylinder and if it gets into your crank the entire bottom end will need to be re-built.
The new KTM’s and Husqvarna’s have one of the most innovative and easiest air filter systems in the industry today with their easy access side panel and tool-less removal they have made air filter maintenance much easier to perform. There is, however, one issue found with the air filter cage on these bikes: all current KTM and Husqvarna air filter cages have an X shaped rough top or tip at the center section that can, without warning, rip a hole right through an air filter. The plastic tip presses right against the center of the filter. Anyone that has installed a filter onto one of these cages can tell you it’s a tight fit and you can easily see how damage can be done to the inside of the foam filter without you even noticing. We have seen plenty of these filters become damaged by this simple plastic protrusion at the top of the cage.
As a result, Nihilo Concepts created the Air Filter Cage Cap to prevent any unexpected damage to filters.
