C&L TRUEFLOW INTAKE PLENUM FOR 02-04 MUSTANG GT

C&L Performance is extremely pleased to offer a truly unique product that is sure to excite all owners of 1996 to present 2 valve 4.6L Mustang vehicles. What we learned during the development and testing for this product is that everyone who has purchased an upgrade throttle body for one of these vehicles absolutely MUST use one of these new plenums to maximize horsepower on their vehicle. Instead of just making bold claims or unrealistic horsepower estimations, we enlisted the help of several independent dyno facilities to put this new product through rigorous testing and to prove exactly how much horsepower can be REALISTICALLY expected. Test results show our new plenum and 75mm TB combo gave a consistent 15-20 rear wheel HP and Torque gain pretty much throughout the power curve.

Realistically, the installation of this plenum and 75mm throttle body on very mildly modified vehicles will add at least 8 rear wheel horsepower, and it is possible to receive as much as 11-15 rear wheel horsepower and up to 20 ft/lb of torque on more heavily modified vehicles with a good combination of bolt-ons. Supercharged vehicles can expect even bigger gains, where improvements of between 15-25 HP should not be uncommon.

Something that cannot be stressed enough is that the performance of this product is STRONGLY dependent upon which throttle body is used. Although most people will commonly feel that a 75mm throttle body is overkill on a naturally aspirated 4.6L engine, our dyno testing, and the dyno testing of many others has proven otherwise. Prior to the release of this new plenum, even a 70mm throttle body was quite useless when using the factory upper intake plenum.
