Simplistic Garage Complete 75mm Throttle Body Kit (HR/VHR2003) VQ35HR/VQ37VHR G35 07-08 350z G37FX37 370Z Infiniti Q50 Q60

This kit is designed to increase the throttle body diameter for the VQ35HR and VQ37VHR engines from 60mm to 75mm.
The bigger diameter bore and allows for greater airflow into the engine which produces a wider power band and better throttle response. Dynographs have shown peak whp gains of 6 hp and 11 wtq, while showing more significant gains in the top end of up to 10 horsepower past the peak. Additionally, the torque curve is much more consistent throughout the rpm range.
This adapter is designed to provide sufficient mating surface area while using the minimum amount of material to remain as lightweight as possible.
Additionally, the bore is bell shaped to match the bigger throttle body and is 5mm bigger than the factory intake diameter to allow for smooth airflow through the product, as well as accommodating those who have ported intakes.
The adapter is precision machined from 6061 aluminum and is 1/2 inch thick.
For off-road use only and to be installed by a professional.
