This Air Filter is offered in multiple sizes and shapes to suit almost any design and car make. It can also be stretched for up to 1.5mm to fit in-between sizes. All Universal air filters are built using high-performance, strong, molded pliable rubber flanges which absorb vibrations and provide for secure attachment. The cotton gauze design is very efficient at filtering dust particles, dirt, and debris. It is designed to smoothen and straighten airflow, reducing air-restriction in the system. This allows your vehicle's engine to breathe in a larger amount of air which allows for more usable power and acceleration throughout the engine's RPM range. This K&N RC 1060 Universal air filter is washable and reusable.
