Show original supplier description
This kit replaces the stock throttle body with a larger 70mm unit, providing a 10mm increase in outer diameter and a substantial 36.1% greater area at the blade compared to the factory 60mm throttle body. Crafted from a CNC billet aluminum adapter plate, the kit ensures durability and precise fitment. It includes a Nisformance Plug & Play adapter harness for straightforward installation. The design features a very low merge angle between the throttle body bore and the intake manifold inlet, promoting a smooth transition and minimizing turbulence for optimal airflow. It promises improved throttle response and driveability characteristics, with proven dyno and track gains to support its performance claims. This product is part of Engineered Parts Solutions and Tuning, LLC's research and development for high-output Nissan/Infiniti vehicles.
