OEM Upper Intake Manifold

alfredo24pr · 02-16-2015, 11:33 PM

For sale is a used OEM Upper Intake Manifold removed from my G37S Sedan. Switched to the M370 a while back. Kept it for a bit just in case, but I don't need it anymore.

Had about 35k miles.
$150 shipped via USPS Priority Mail.

why didn't you just get it ported? Also how do you like the M370 so far. get a tune yet

I thought the M370 would be better than getting it ported. After trying out the M370, I think getting it ported would have been cheaper and probably as efficient or better.

I'm tuned with all the bolt ons except headers. The M370 made me lose power throughout the entire powerband. Maybe it was a bad dyno day, but the tune managed to bring it back up.

Lose power? please explain. Did you get a tune with your stock mani and then switch to the m370 and lose power? better gains with the m370?

This is a dyno after installing the M370. No tune.

Blue Line: FI RHFC, Stillen Gen 3, and ARK Exhaust (on the stock manifold and no tune)

Red Line: same mods and M370 installed (still no tune)

This other dyno chart is with the same mods (including M370, but Uprev tuned)

Do you know if it will fit my 2009 370z base manual. Are they the same? Also when I change spark plugs is that the best time to change it out due to labor? thanks. checking into porting so I might be interested

It should fit...I don't think there is a difference between the g37/370z 6sp or 7sp manifolds. According to the info I found, it should fit on any VQ37VHR engine, including the 370Z & G37.

This manifold could be ported locally if you want to save money or you can send it to Z1 for a porting job. Here is some good info:

Not sure about the spark plugs.
