Can anyone tell me what this is for? I thought it was part of the SAI system, which i have removed. Ive got a powerbox fitted off of flame and hooked this up to the vacuum system, is it actually needed. If i block one end the revs drop a little, if i let it breath, it sucks in air and increases the revs a touch.




Cheers
Tom

i dont think it is EGR. the egr sits at the back of the inlet/under the inlet and is a big chunk of metal bolted to manifold...this is some sort of vacuum pipe and im almost 100% its SAI and not needed. The rest of the SAI is gonesville anyways...might just take it off and see how she runs.

I think (Although not 100%) Its part of your brake servo?And also it has something to do with the SAI.

I think you need it anyhow,So i would just leave it!
