COMP Cams Mustang XFI (NSR) BG Stage 1, 3V

XFI NSR (NO SPRINGS REQUIRED) FORD 4.6L/5.4L MODULAR 3V CAMS
The COMP Cams XFI NSR (No Springs Required) Cam Sets for Ford 4.6L/5.4L Modular 3 Valve 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 one cam set is designed to maximize mid-range power and torque, while stage two maximizes top end horsepower.

SOHC-(Blower Grind, Stage 1) Excellent mid-range cam for bolt-on blowers with stock boost levels. Great power gains above 4700 rpm, compatible with stock springs. Best with stock gears.
