2000GT4.6

You can argue about what are "boltons", but the generally accepted version of full boltons is:

Manifolds, midpipe, catback, some sort of CAI or filter, MAF, inlet tube, throttle body, plenum, underdrive pulleys, tune (arguable) and gears.

You can argue that cams are a bolton part, but people will say they have cam's in addition to full boltons.

haha I consider my car to be a full bolt on +. Bolt ons I would consider anything that you bolt on to the out side of the engine without having to tear into it or upgrade the engine to handle it.

Well i say ive got full bolt ons and thats becuase i have every possible (legitimate) 4.6 engine mod other than forced induction, N20, or ripping apart the engine (heads, cams, pistons) Hmm i guess i still need an alluminum driveshaft and a lightning MAF but i do have a ported MAF and the lightning one would be pointless becuase im not pulling in enough air for that to be effective.
