Hey quick question, does it matter if the FI HFC's were sold to a MT g37? Looking on craigslist and found one for cheap but idk if they are interchangeable, I got a g37x 7at sedan and wanted to know if anybody here knows if they would fit my car.

 

if its just the HFCs, they are all the same (6MT/Auto/Coupe Sedan RWD AWD)

 

ok thanks

 

My understanding is that the FI HFCs are slightly different diameter for coupe (2.5") and sedan (2.25"), but both will work with either, and that is the only difference.

If you have a 2.5" CBE, the coupe HFCs may provide less rasp since they are also 2.5", but that's about it.

RWD/AWD/6MT/Auto don't make any difference

 

This is a better answer than I gave earlier I only considered fitment (i.e. they all fit), not sound quality.
