Brand new in factory box with all hardware and instructions.
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.
works with all OEM and aftermarket intake systems which bolt to the stock throttle body location. 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.
170% improvement in heat resistance, up to 500 degrees F.
Lowers operating temperatures by approximately 50 degrees F.
20% more volume than factory.
Completely smooth underside with no flow restrictions.
Equalizes flow to all cylinders. Factory plenum utilizes a very aggressive angle and caps off the front cylinders.
3lbs. lighter than factory plenum.
Made in the USA!
No drilling, cutting, or modification necessary.

Lifetime Warranty on NA (naturally aspirated) applications and FI (supercharged and turbocharged) applications up to 15psi.
