Comp Cams 2005-2010 Mustang 4.6L GT Cam Phaser Limiter Kit limits the movement of cam gear to no more than 20 degrees. Allowing more piston to valve clearance all while keeping wide-open throttle benefits of cam phasing.
What does the Phaser Limiter Kit do? These limiter plates replace the factory back-plate on the cam phaser. They have posts which extend into the cam gear's control chambers, limiting their movement to no more than 20 degrees. This gives more piston to valve clearance and lets you install bigger, more powerful camshafts while keeping safe piston to valve clearances. Keeping the movement to 20 degrees, all the wide-open throttle benefits are retained, since normal retard the cams see at wide-open is only around 9 degrees
Do I have to reprogram the computer? Yes, you MUST reprogram your engines computer for the engine to operate properly after installing the cam phase limiters. The guide lines are simple for reprogramming - just make sure that the maximum retard entered for any of the cam phaser tables and DTC strategies in your tuning software does not exceed 20 degrees.
Kits includes 2 limiter plates and installation tools
