Improved Performance For Ford Mustang

Boost your Mustang’s performance with the Ford Performance Improvement Intake Manifold, designed specifically for the 1996-2004 Mustang GT. Built with brand-new tooling, this composite manifold offers a direct OE fit and is manufactured to the exact standards of the original part used in Ford’s 2001-2004 GT 4.6L 2V Mustangs. What sets it apart is a series of engineering enhancements: a larger bell mouth, shorter and more rounded runners, and a deeper plenum. Together, these features optimize airflow to your engine, promoting better throttle response and delivering more power when you hop on the accelerator. Each part is precision-crafted to ensure you’re getting top-tier performance straight from Ford's engineering.

For Power Improvement Heads

This manifold upgrade is ideal for drivers performing a PI (Performance Improvement) head swap on older Mustang models, specifically the 1996-1998 4.6L engines. With this intake manifold, you get an affordable yet highly effective alternative to costly aftermarket parts, providing an OE fit that makes installation straightforward. However, for those with 1999-2000 Mustang GTs, an additional alternator bracket from a 2001-2004 GT will be needed for proper fitment, along with a few specific gaskets for a reliable seal. Plus, the intake features a durable composite plastic body with a corrosion-resistant aluminum crossover, giving you a balance of lightweight construction and resilience. While this manifold is recommended for off-road use only, it’s an excellent upgrade for dedicated Mustang enthusiasts looking to make the most out of their rides.
