Brand new in factory box with all hardware and instructions, including permanently adhered flange gasket that is to be used with the factory gasket as well as a new throttle body gasket.
A direct replacement for the factory upper plenum.
Has shown a solid peak gain of 14rwhp and a consistent gain throughout the entire RPM range on 03-04 (non Rev-Up).
Works with all aftermarket intakes. Retains all factory mounting points.
DOES NOT work with plenum spacers. The upper plenum works in a similar fashion to the plenum spacer by increasing volume in the plenum and flow to the front cylinders. It cannot be used with a plenum spacer because the center of the Kinetix Upper Plenum rests on the lower plenum. Without that support, the suction into the cylinder could break and collapse the plenum. The use of a spacer does void the Kinetix Lifetime Warranty.
Allows use of stock strut bar and engine cover. Engine cover may not fit with the Infiniti FX35 and G35.
Versatile and strong, composite plastic construction.
170% improvement in heat resistance, up to 500 degrees F.
Lowers operating temperatures by approximately 50 degrees F.

Equalizes flow to all cylinders. Factory plenum utilizes a very aggressive angle and caps off the front cylinders.
