going to buy a GT40 intake tomorrow and it comes with TB...do they still use the egr spacer like the stock intake uses. or will I have to get one of them to match the throttle body
Typically you want the EGR spacer to be the same size as the TB. I think the stock one is 60MM and the factory opening on the GT-40 is 65MM. If you're on a budget the factory spacer can be opened up to the correct size.
