Air Filters are the lungs of the engine, they clean the incoming air by capturing dust and dirt. It's important to get the right air filter as the wrong air filter could mean very costly engine repairs. We have been using and selling Twin Air filters for years and have never had any problems. Twin Air filters are standard fitment on European bikes like Gas Gas and KTM. The filters are made using 2 different foam densities, an outer more open pour layer along with a finer smaller pour inner. Keep your bike going strong for longer with correct air filter maintenance and Twin Air air filters. Select your year, make and model to order as different year models have different filters.
