VQ35HR / VQ37VHR Ported & Ceramic-Coated Throttle Bodies – G37, 370Z

Improve airflow and throttle response on your VQ35HR or VQ37VHR engine with our fully ported and polished throttle bodies, built for the Infiniti G37, Nissan 370Z, 2007+ G35 Sedan, and 2007+ 350Z HR. These are precision-modified to remove airflow restrictions that hold these engines back from making efficient power.

Each throttle body is ported 2–3mm and the internal surfaces are polished for smoother, faster airflow. Pair this with tuning and supporting mods and expect 6–10 HP gains plus noticeably sharper throttle response.
