Plenum spacer - 1/2'' or 5/16'' for an 03 coupe?
Here are my gains for the 1/2" MD spacer with ISO Thermal Kit. I had no loss in power on my 2003 G35C 5AT.

this is probably a stupid question ( ^_^ ) but with the iso thermal what if you're lazy and don't want to frig around with opening/closing the valve when it goes below/above 55deg. F.........should you just leave it open or closed?

I thought the air intake blocks the CCV so you've got to bob and duck and twist like a contortionist to reach it?

You, my inquisitive friend are stuck between a jelly bean and a marshmellow.
Motordyne affords a fine alternative for extra power. However, like everything else . . . You need to apply a bit of effort to reap the profits.
