The cabin air filter is made of high quality activated carbon, which has good adsorption effect, and can effectively filter out fine dust particles, dirt, smoke, odor, pollen, etc., to ensure that the cabin circulates clean and fresh air. The engine air filter has more folding layers of filter material, increasing the filter area, better filtering and protecting the engine from particle damage, while the gaskets provides a tight seal to ensure that only filtered air reaches the engine. Easy to install, only about 10 minutes can be easily installed, no special tools can be installed directly, saving you a lot of time and cost. Recommended replacement every 12,000 miles.
