I am looking to modify my Explorer and only have found cat back exhausts, CAI's and high flow filters commonly available for hp/tq increase. Has anyone used parts for the Mustang GT on their 4.6L 3 valve such as cam, intakes, heads and forced induction?

 

Most of the Mustang stuff will make more power, but move the powerband into the higher rpms and will cost low end torque. Supercharging like the Roushcharger will make a big difference!!

 

Turbo, supercharge or spray will work with spray being the least expensive at the start. The engine will do fine if the spray is used in moderation.
