Port/Gasket Matching on IM, Spacer and TB?
Getting ready to install the 3.7 IM & TB, MDX spacer and P2R spacer. Now I'm wondering if port matching all of this first would make a significant difference in gains and fuel economy.
I can see the inlet of the intake is quite a bit smaller than the throttle body and P2R spacer:
Downstream, the intake is ~2mm smaller than the MDX spacer, which is ~2mm smaller than the P2R thermal gasket. (not sure how the runners compare yet since I haven't removed the stock IM yet):
Any thoughts on whether it would be worthwhile to first get everything (including the runners) ported, polished and matched?
