Variants & Setup

Larger bore sizes (38-40mm) suit more heavily modified engines with supporting cam/head/injector work, while 32-34mm is a milder upgrade over stock; an oversized throttle body without matching engine work can hurt low-end response. Match bore size to your build with your tuner's input.

Installation & Package

Installation replaces the stock throttle body and typically needs ECU remapping/fuel tuning to run correctly, especially at larger bore sizes - done by an experienced mechanic/tuner. Package includes the throttle body with CNC-ported intake; your stock injector and sensors are normally transferred over.

Summary

HPSP Racing oval CNC-ported throttle body for Y16/Y16ZR, available in 32-40mm bore options.

Important Notes

A larger throttle body changes fuelling and usually needs a tune/remap to run properly and avoid a flat spot or rich/lean condition - budget for tuning alongside the part. Confirm your Y16ZR variant/year before ordering.
