Sweet thanks. I just ordered it.it should be in next week.

 

You will need either an inch-lbs torque wrench or a leather glove and a nut driver. If you have either, the hardest part is out of the way.

 

OT, 03 base, were u on bimmer forums? i feel like i remember that name when i had my bimmer and always saw u in the kills section lol

 

I have a 03 g35 6MT, how do I know if I have a REVUP engine? I read the forum but couldn't find where to find it. I seen a post about a rev light at the dashboard, I don't have one so does that mean I don't have a REVUP engine? Would just the 5/16" ISO Thermal Plenum Spacers work then? I would buy the MREV2 but not if it won't work.

 

Rev ups were only available on the 05-06 models so you won't benefit from the MREV2. So get a spacer and install that puppy.

 

So being in California where it's minimum of 60 degrees and tops 95 where I live, should I get the 5/16" ISO Thermal Plenum Spacers then?

 

^Yes

 

i realize this is an old *** thread but instead of me making a new one ill just add to this one quickly, i live in NYC my 06 G35x is my daily driver, im looking into MD 5/16 Iso thermal and the copper . . . what do u recommend ?
Thanks

 

Since you see all 4 seasons, you could either get the full package (Copper ISO thermal kit w/spacer) or just do the plenum spacer by itself which is the cheapest. You would want to keep the ability to run engine coolant to the plenum to keep the throttle body from freezing in the winter. The gains from using aramid gaskets and bypassing the coolant are small and can only be noticed on a dyno.

 

Hey guys, I have a 2003 sedan and i was playing on getting a 5/16 plenum spacer and I live in Colorado. Do I need anything else like a thermal kit with it??

 

As said above, the thermal kit is just another bonus to keep air intake temps a bit cooler. You could run it but it is not necessary at all.

 

Another question. I have an 05 auto. Any benefits to installing an mrev2 or just go with the spacer?

 

^Cost outweighs the benefit so just go with the spacer. Unless cash isn't an issue

 

Great, thank you!

 

So it won't affect the car if I don't get it?
