This new intake plenum replaces the upper half of the 2003-2006 Infiniti G35 Sedan and 2003-2007 G35 Coupe factory intake manifold. This plenum bolts directly up to your G35 with zero modifications. ** Engine cover may not fit **
This plenum increases the volume to the middle and more importantly the front cylinders. The factory plenum utilizes a very aggressive angle as it caps off the front cylinders. This new plenum equalizes the flow to all cylinders, while also increasing the total plenum volume. This plenum also uses a very versatile plastic to achieve a smooth interior for superior flow properties. The plastic also allows a lighter overall weight, by about 3 lbs. The overall temperatures of the plenum have also decreased by about 50 degrees farenheit. This helps with heat soak problems and to help lower air intake temperatures.
This plenum has shown a solid peak gain of 14 rwhp and a consistent gain throughout the RPM range. When matched up with high flow cats, they together have shown peak gains of 20 rwhp.
The plenum still retains all factory mounting points and also includes all necessary new hardware. The plenum also includes a permanently adhered flange gasket that is to be used with the factory gasket as well as a new throttle body gasket.
