COMP Cams Camshaft Set XFI NSR Stage 1 For Supercharged Engines 4.6L 3V GT 2005-2010

The COMP Cams XFI NSR (No Springs Required) Cam Sets for Ford 4.6L/5.4L Modular 3V Engines are the first truly "drop-in installation" camshafts ever created for this popular application - striking the perfect balance of performance versus installation difficulty.

Offered for both naturally aspirated and supercharger-equipped engines these cam sets require no additional computer re-tuning; however testing has shown that mild tuning can result in power gains even greater than the normal 25 rear wheel horsepower.

These camshafts are fully compatible with the factory variable cam timing (VCT) system and are designed to operate in the stock RPM range. The stage 1 cam set is designed to maximize mid-range power and torque.
