if you are keeping the standard intake plenum, and are willing to cut up the drivers side of engine bay, get pipework like this..(Gibson motorsport R31 GTSR)
If you just want a hassle free FMIC that doesn't involve any cutting of anything, then get a return flow cooler kit from BLITZ.
Looks like this..
If you want to spend less and still not cut any holes, then get a cooling pro/Just Jap/*insert other ebay kits here*
I sold an ARC return flow kit and replaced it with an R32 GTR core and Gibson motorsport type pipes.
