Blox Racing BXIM-40201-G2 Thermal Shield Intake Plenum Spacer Compatible with G35

Great service as shown and with hardware should have small tube sealer for installation

I have owned it for 6 months now with no issues. At this point in time I do not see a reason to buy a more expensive spacer. It works great, it hasn’t broke, and you can actually feel the gains in the mid to high end.

The circular spacer cracked and eventually broke. Sending a piece into my valve on cylinder 6. Not worth the headache of saving money for this cheap alternative. Learned my lesson

Great alternative to Motordyne and Z1 plenum spacers. No fitment issues and serves the exact same purpose at a fraction of the cost.

Installed this spacer in my 2007 M35x. The M has the same engine that's in the G35. Used RTV to set the six washer/spacers inside the plenum (don't forget them). I reset the ECU. My only other mod is new spark plugs. I haven't had the car dyno'd either before or after, so no clue as to the performance. I always use premium fuel. Using the OEM air intake. No difference in the sound. My butt dyno likes the performance though. The M/G is a great car if you can get your hands on one.
