Trick Flow Upper Plenum for 1996-2004 4.6L 2V Mustangs.Better airflow equals more power. More horsepower starts with more air, as much as 100 CFM of additional air over stock with a Trick Flow High-Flow upper plenum. Made for 1996-2004 4.6L 2V powered Ford cars and trucks, the aluminum plenums have been raised 3/4 in. to enhance airflow yet still fit under a stock hood. They work with stock sensors, are compatible with throttle bodies up to 75mm, and come in silver, black, and natural finishes.
I installed the Trick Flow upper plenum along with a 70 mm throttle body on my 04 mustang gt and the throttle response is much better than before with the factory setup.The quality of the Trick Flow pieces are of good and I'm well pleased with my purchase from cjpony parts.
