Show original supplier description
The Trick Flow Specialties TFS-51800001 is a high-flow upper intake plenum engineered to enhance performance for Ford 4.6L 2-valve modular engines. Its multi-port fuel injection style and 75mm throttle body bore size are optimized for operation within an RPM range of idle to 5,500. Specifically designed for 1996 through 2004 Ford Mustang models equipped with the 4.6L 2V engine, this Trick Flow upper plenum is engineered for a direct fit and ease of installation. A key design feature is its ability to fit under the stock hood, ensuring a clean installation without requiring modifications to the factory setup. The plenum includes a brass 3/8”-18 NPT x 5/8” hose fitting for necessary connections. This upper plenum is compatible with throttle bodies up to 75mm. The product is the top section of the intake only. Based on forum discussions and product descriptions, this intake is considered an upgrade from the stock PI intake and is part of performance-oriented combinations, often paired with Trick Flow throttle bodies and cylinder heads to maximize power gains.
