Ford built a great car in the 2005-2010 S197 Mustang, but with a little help from COMP Cams it can sound and perform like a real "hot rod". The Thumpr Ford 3 Valve Cam Sets for 4.6L/5.4L Modular 3 Valve Engines deliver a great idle with excellent power. Good mid-range torque & power gains above 4500 rpm. Compatible with stock valve springs, converter & gears, and requires cam phaser upgrade & custom tuning.These cams will turn your naturally aspirated or blower-equipped Ford 3 valve engine into a performance machine with a minimum of installation difficulty; only requiring the addition of the COMP Cams Cam Phaser Limiter Kit (#5449) and computer tuning. The COMP Cams Cam Phaser Limiter Kit (#5449) safely modifies the factory variable cam timing (VCT) system allowing for the use of aggressive camshaft lobe technology without sacrificing the benefits of the VCT. Extensive testing of these new camshaft combinations has confirmed repeatable power gains of 25+ rear wheel horsepower with no sacrifices in long term durability.

Product Benefits
  • Delivers an aggressive "thumping" exhaust idle
  • Generous power gains in the middle & upper rpm range
