Designed to bolster your engine's efficiency and performance, reusable air filters give your vehicle room to breathe and help save gas. But, that's not all. Cotton gauze air filters also strip out more contaminants than traditional paper air filters, protecting your engine's guts from damage while allowing your motor to work more efficiently. What's more, you can keep using your replacement air filter for nearly a million miles. When it starts to get dirty, simply clean it off, add some more oil, and pop it back in-good as new.
