DT-1 has been an air filter manufacturer for over 30 years, chosen by many professionals and sold worldwide.
The DT-1 air filter cage is made of aluminium and is stiffer than the original plastic one. It eliminates the need for a flame arrestor when used with the specific DT-1 oil. It also allows for better sealing between the filter and the airbox.
