Can someone let me know if there is a difference between the AU Fairmont V8 manifold and the XR8 one.

I have the tickford cold air system from an XR8, K&N airfilter as well as extractors and exhaust, this was supposed to be the difference between the power outputs of these 2 cars (Series1) but I was wondering if getting the XR8 tickford manifold would make any difference?

Cheers.

They are the same inlet manifold.

The series one XR8 and the Fairmont V8 are the same in all respects with the exception of the headers and the exhaust (and possibly EEC tuning).
