Manufacturer application source ↗

Applications shown here are limited to the configurations we documented. Use the manufacturer’s vehicle selector and confirm your engine, transmission, trim and part number before ordering.

THE PURPOSE

What it does.

This reusable, oiled panel filter replaces the filter element in the original airbox. It is a replacement-filter option, rather than a complete intake system.

THE TRADE-OFFS

What to consider.

Choose it for its service approach, not a promised horsepower number. Check the housing and part number; facelift BRZ applications can differ by transmission. A disposable replacement remains another option.

THE WHOLE JOB

Plan the installation.

Follow the manufacturer’s fitting and cleaning instructions. Seat the element correctly and inspect the airbox seal. Include the correct cleaning supplies in your ownership budget.
