See If This Product Fits Your Vehicle
Upgrade your 2003–2004 Ford Mustang Mach 1 4.6L with the JLT Ram Air Intake system. Designed with a large 4.25" roto-molded plastic intake tube, this kit provides unrestricted airflow while resisting engine heat for consistent cold air delivery. The Mach 1-specific ABS heat shield blocks engine heat and is compatible with the factory shaker system, ensuring peak performance during low-speed and idle conditions.
The kit includes a high-flow, reusable S&B 4x9" cotton gauze air filter with red oiled finish to maximize airflow and protect your engine. Installation is straightforward with heavy-duty clamps and all included hardware, and the intake works with both 80mm and 90mm MAF sensors. Expect gains of 10–14 RWHP over stock, with optimal airflow and throttle response for track or street driving.
