Show original supplier description
It is primarily used on fuel-injected engines to improve airflow and power output across a broad RPM range, making it ideal for street and moderate performance applications. Crafted from durable aluminum, this intake manifold features a natural satin finish that combines strength and corrosion resistance with an attractive look, ensuring consistent performance and longevity. It has an operating RPM range from 1,500 to 6,500 RPM and is equipped with EGR. Injectors, fuel rails, and throttle body are not included, though no aftermarket fuel rail is required. Runners are included and removable. Specifically designed for the 1999-2004 Mustang GT with two-valve heads, modifications may be necessary for other 4.6L applications. The product information notes that stock cams only rev to 5,400 RPM, and aftermarket cams are recommended for maximum benefit. Installation is described as straightforward for experienced mechanics familiar with EFI systems, not requiring drilling or extensive modifications on compatible engines. The product includes a 12-month limited worldwide warranty.
