Why wouldn't you just get the Skunk2 intake manifold.
1. Its already made to fit up to the gsr
2. It's just as good or better then the Type R intake manifold
and 3. Why waste money trying to get the Type R intake manifold to fit up to the gsr??

I have the Skunk2 intake manifold on my gsr and it's definetly worth getting. I noticed a very good high end power gain from it.
