350z g35 Intake Manifold Set

If you have ever look at the Motordyne MREV2 and thought “does it really work?”. Well… the simple answer is: YES. But we here at Shift Tech Performance thought we would take it a step further with additional machining and some cosmetic options. This 350z g35 Intake Manifold will add power and efficiency to both the vq35de and especially on the rev-up engines. Pick up both our Shift Tech Performance Lower and V2 Upper together as a package and save big!



350z or G35 Lower Intake Manifold

The two front runner are machined down on the 350z g35 Intake Manifold to promote better air supply to the front two cylinders which are typically starved of air. Even without a plenum spacer, you will experience a substantial increase in throttle response, low/mid range hp and torque, and a small bump in overall hp on the top end.




350z or G35 V2 Upper Intake Manifold

Shift Tech Performance took a unique approach to the V2 upper 350z g35 Intake Manifold. By machining down the center support pillars and rounding everything off, we are just removing 6 additional obstacles that inhibit air flow. Grinding off the cast flashing and pitting out of the neck and underside of the cover is also completed to ensure you get the utmost efficiency from your plenum. The V2 upgrade includes a ported neck and custom flange, welded seamlessly in the OEM position, that allows you to run the larger 75mm throttle body as if it was originally designed for it. No step down in diameter to meet the oem flange and a clocked over throttle body that can cause the corner to hit the underside of the hood with many owners. This takes the proven power increase seen with the larger throttle body via the adapter flanges, and maximizes the efficiency to give you the unsurpassed edge vs any other build options! The V2 upper will come with the optional throttle body and wire harness adapter so it is all Plug ‘N Play, no tune required, through strongly recommended for best results. This is an amazing options for cleaning up your engine bay and unlocking unmatched performance for any vq35de Or rev-up engine in your 350z or G35!
