I been reading a few posts here and there and i've read that a pathfinder throttle body which is hard to find, works real well on the 4th gens, is it installable without any major modifications? does it just replace the stock throttle body? anyone mind helpin out with some info here?

 

What other mods are you planning that necessitates a PathfinderTB?

The all-motor section has good info on this BTW.
