Feature●The Car Engine Air Filter provides clean air to your engine to prevent dust and impurities from entering the engine and affecting combustion efficiency. Say goodbye to delayed acceleration and less than average gas mileage●The filter media is made of high-density, highly breathable long-linted electrostatic cotton, which can well absorb dust and debris in the air, and the multi-filter paper pleat design allows the air flows to be unaffected even when the filter is dirty●Thanks to the large-capacity filter technology, more dust and debris can be captured, which means that the air filter can last longer and avoid frequent replacement under normal driving conditions●OE-design for install directly. No special tools and modifications are required.
