Product Description

The AIRAID 720-128 Universal Oval Air Filter is a high-performance replacement designed for custom intake systems or as an upgrade where a direct vehicle-specific filter isn't available. It uses a premium multi-layer combination of cotton gauze and synthetic media to maximize airflow while still capturing dirt and debris effectively for engine protection. Its washable, reusable design helps lower long-term maintenance costs compared to disposable paper filters.

This universal clamp-on filter with a 4.5" (114 mm) inside diameter flange and tapered oval shape fits many aftermarket intake tubes and custom applications - just confirm flange size and space clearance before purchase. Installation is straightforward with basic tools, and the flexible frame helps adapt to diverse mounting scenarios. Backed by AIRAID's No-Hassle Lifetime Limited Warranty and proudly made in the USA, the 720-128 offers durable performance and enhanced airflow potential for a wide range of performance builds.
