What to know before buying

Universal describes the connection options, not guaranteed vehicle compatibility. Measure your intake connection and available fitting space, then confirm the filter can be secured in your setup.
The claimed airflow, throttle-response and engine-protection benefits are manufacturer statements, not independently verified performance results. Follow the supplied care instructions and keep installation clear of moving parts.

Frequently asked questions

Is the filter washable?

The listing describes it as washable and reusable. Follow the supplied care instructions.

What fittings are included?

The product details specify two adapter rings and one metal clamp. The broader included-components field also lists a hose, so confirm the selected listing's package contents if the hose matters to your installation.

Are performance improvements confirmed?
