hi, i just got my two first mods for my car, true duel exhaust sytem and a K&N CAI. now im lookin for something else that isnt to costly but'll give me the most bang for my buck. should i get a underdrive pully? or would you guys have any other suggestions?

honestly man if ur plugs havent been changed in a while id go get some bosch 2 prongers i could tell a huge difference in my cars acceleration and btw you have catalitic converters or no?

Gears, t-lock, and underdrivers........ Stay with autolite, motorcraft, or NGK copper plugs.

Listen to Shiner. He knows what he's talking about.
Plugs don't add significant HP. and by significant in this case I mean more than 1 hp.

Warning: Bosch platinum plus are probably the worst thing you can put in your mustang.
