will the arc oil catch tank for the 350Z fit on the G35? i got a pretty good deal on one so i wanted to know... also whats the benefit of having one?

 

I don't really know a lot about this mod on our cars, but I do know a few people who have oil catch cans... and they only got them because they had oil building up in their intake pipe and some would drip down to the filter(potentially fouling the MAF Sensor). I know O'Scottie from 6MT has one on his car, maybe you could talk to him and get some feedback on if he actually catches any oil in it.

If you don't have that oily-intake problem, I'd probably save the money or spend it on other more important mods.
