Question?? Help please
 

My mate is having a clear out he has a inlet manifold off new age Impreza. Now the question is. Is there a difference between WRX to STI
as some one asking wether it's a spec C? I'm not Familiar enough with them to know if there's a difference and how to spot. Thanks in advance. ;)

wrx has tgv tumblers that bolt to the inlet, STI has tumbler deletes (flaps removed) that also bolt on and spec c is a 1 piece manifold.

WRX is plain colour, STI/Spec C is red

Thanks that's a big help :D
