Airaid Kit Replacement Filter - 720-478

The Airaid 720-478 Kit Replacement Filter is a direct-fit performance air filter designed as a replacement for Airaid cold air intake and intake kit systems. If you've already invested in an Airaid intake kit and your filter has reached the end of its service life — or if you simply want a fresh, high-flow filter on hand — the 720-478 keeps your induction system performing the way Airaid intended without the need to replace the entire kit.

Key Features & Benefits

Fitment

The Airaid 720-478 is a replacement filter intended to pair with specific Airaid intake kit applications.

Q: Is this a washable, reusable filter or a disposable filter?

A: Airaid filters are designed to be cleaned and re-oiled for continued use rather than discarded after a single service cycle, which is a hallmark of Airaid's filter lineup.
