Spec C Manifold and fuel rail
I'm not sure who can help me with this question but will throw it out there
Some of you will know that the Spec C manifold is a one piece unit, unlike the STI manifold which comes in 3 different pieces.
It comes with the TGV delete, which improves flow.
I've been informed by various sources that the spec c unit unlike the STi one will only accept the OEM fuel rails and no other aftermarket rails.
Without having a spec c manifold, i can't test this theory.
Can anyone confirm this?
Thanks
