[Kev-iVT]

Ive got a 4-1 manifold that came off my bros ek that im gonna try an fit to my crx. I know that the lambda sensors have to be fitted up near the mounting flange at the head just wonderin which pipes they need to be fitted into? Ive got 2 m18x 1.5 nuts already an ill weld them in after i know which runners to drill.

It doesn't really matter. I'd put it on 3 and 4 and fit them from the left side. This way, they won't get in radiators way.
