Product Description

The Roush Performance Replacement Air Filter (089999-00006) is a dry cotton gauze conical filter designed as a direct replacement for the air filter element used in compatible Roush Performance cold air intake systems for the Ford Mustang and F-150. It replaces Roush's own filter part number 131550-9601R-S and fits a wide range of Roush CAI kits spanning the 2015-2026 model year range across 2.3L EcoBoost, 2.7L EcoBoost, 3.5L EcoBoost, 3.7L V6, and 5.0L V8 applications. The dry filter design requires no oiling, simplifying maintenance while keeping the intake system performing at its rated airflow capacity.

The cotton gauze media is supported by inner and outer wire mesh layers for long-term shape retention and durability. The filter is fully washable and reusable, making it a cost-effective long-term replacement over disposable paper filters. At 6 in. in diameter and 9 in. tall, the conical design maintains a high-flow surface area to minimize restriction at wide-open throttle. A clamp is included for installation. Always verify your specific Roush Cold Air Intake kit number before ordering to confirm this filter is the correct replacement for your application.
