VQ35DE Ported, Polished, & Ceramic-Coated Throttle Body – 350Z / G35

Increase airflow and throttle response on your VQ35DE engine with our ported and polished throttle body, designed for all 2003–2006 Nissan 350Z and Infiniti G35 models, including both DE and RevUp engines. This upgrade removes factory restrictions and allows your VQ to pull air more efficiently across the entire RPM range.

Each throttle body is ported 2–3mm over stock and the internal surfaces are polished to reduce turbulence and improve air velocity. With proper tuning and supporting mods, expect 5-10 HP gains along with a sharper, quicker throttle response.
