Hi all checking my oil tonight and noticed my car has yellow injectors fitted what size are these mine is a 99 uk turbo are these the correct ones i gather different colours are the sizes but correct me if im wrong also ive been looking at sti inlet manifolds does these differ from normal turbos ie bigger bore or larger throttle bodies etc and are they a straight swop thanks

 

Injectors are 440cc mate, and they do come on as standard,
AFAIK manifolds are the same.

 

I can't see the benefit of swapping, the only inlet that will be of an improvement is one from a version 1 or 2. However this won't fit your car, if you are going to change your inlet you need to make sure it's a phase 2 one you use otherwise it won't fit your heads
