Product Description

The Roush 402099 Cold Air Intake Kit is a purpose-built performance upgrade designed for naturally aspirated 2005-2009 Ford Mustang models with the 4.6L V8 engine. By replacing the restrictive factory airbox with a tuned intake system featuring an oiled, washable filter and high-flow tube, this kit helps your Mustang breathe cooler, denser air - translating into improved throttle response, increased airflow, and a more aggressive induction sound.

Installation is straightforward: the system uses the existing mounting points and hardware, eliminating the need for PCM recalibration or modifications to the vehicle. Every component is engineered using OEM CAD data for precise fit and finish. The Roush intake enhances both the look and performance of your engine bay, making it an ideal upgrade for street, weekend performance, or enthusiast-level builds. Note that this kit does not fit ROUSHcharged® vehicles and may have emissions legality limitations depending on model year and state requirements - always check local laws before installation.
