COMP Cams Springs and Phaser Mods Required XFI Stage 3 Camshaft Set for Naturally Aspirated 2005-2010 4.6L 3V Mustang GTs.

The COMP Cams® XFI™ SPR (Springs and Phaser Mods Required) Camshafts are the best way to achieve the most horsepower and torque increases possible with the popular Ford 4.6L/5.4L Modular 3 Valve engines.

Available for both naturally aspirated and supercharged engines, these cam shaft sets are offered in three performance levels. Designed to work with a modified Ford variable cam timing (VCT) system, these camshafts are direct replacement components.

Working with the required COMP Cams® Cam Phaser Limiter Kit (Part# 5449; patent pending), these XFI™ SPR Cams optimize both low and high RPM performance. As noted by the COMP Cams® engineering staff during extensive dyno testing, these camshafts provided the biggest power and torque improvements of any cam series they’ve ever tested in the Ford Modular 3V engine.
