350Z Twin Plenum Twin Throttlebody Intake Manifold

Watch our Youtube video with this plenumon our 350Ztt!

In our pursuit for perfection, we quickly realized the the intake manifold on the VQ35 motor was not ideal for maximizing power.It comes in multiple pieces and is very restrictive.The runners at the front of the motor get less air then the runners at the back of the motor. This means that a lean condition can occur, which could destroy your motor.In order to address this situation, we designed an intake manifold that flows equally across all six cylinders.We also increased the volume in the plenum to maximize power.The Speed Force Racing intake manifold replaces the stock unit with a piece of art that performs even better then it looks.This intake is also perfect for direct port nitrous set-ups.Thsi si also the plenum that you will need to eclipse the 1000WHP barrier on the VQ motor.We have seen peak gains of 30ft/lbs of torque and 30 horsepower at the wheels on low boost (7.8psi)Forced Induction cars! The Speed Force Racing Intake Manifold for the 350Z and G35 is built entirely out of 5052 and 6061 aluminum.Each runner utilizes a velocity stack to maximize airflow and broaden your powerband.Each plenum is formed out of a flat sheet os .125 wall aluminum for superior strength.These intake manifolds are capable of withstanding 50+ psi of boost!Every SFR intake manifold comes with provisions for the stock components. We can weld bungs and fittings for direct vacuum connections,MAT sensors,etc…… for FI vehicles.
