While it is true that the stock airbox system on the GTR is excellent, through careful testing we were able to develop a system that adds significant mid-range torque and horsepower while improving boost response.

The Harman Motive Intake System draws cool air by placing large conical filters inside the front bumper. It completely replaces the stock airboxes and MAF housings.

Installation requires removal of the front bumper. The Nissan bumper is well made and easy to remove/install. No cutting or permanent modifications are required for the installation of this intake system.

The Harman Motive intake sounds incredible on the GT-R. By placing the filters outside the engine bay, air induction and bypass (blow-off valve) can be heard during aggressive acceleration and shifting. However, the intake is quiet during cruise and does not have an annoying "sucking" sound during normal driving.

On the dyno, Harman Motive's intake system made +8WHP and +18TQ while improving spool by 300rpm. All testing was performed on the same car on the same day, they never removed the car from the dyno. Tests were performed with the hood closed and the vehicle fully warmed up. You can see a decrease in intake temperatures throughout the run with the Harman intake - an impressive result given the excellent engineering of the stock airbox.
