COMP Cams Camshaft Set XFI SPR Stage 3 For Supercharged Engines 4.6L 3V GT 2005-2010

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.
