Variants & Setup

32mm matches the factory-standard Y15ZR/LC150 bore and needs no extra tuning; 34-40mm are performance upsizes that increase airflow but typically require ECU remapping/fuel tuning and a matching intake manifold to run correctly - not a bolt-on-and-forget upgrade.

Installation & Package

Installation replaces the stock throttle body and connects to the factory injector wiring; ECU tuning is recommended after fitting sizes above 32mm. Package includes 1x throttle body unit in the selected size; injectors/sensors beyond the body itself are not confirmed included.

Summary

HPSP Racing Oval Double-Injector CNC Throttle Body for Y15ZR/LC150/RS150, available from 32mm to 40mm bore.

Important Notes

Confirm your engine uses the oval intake port (Y15/LC150/RS150 family) before ordering, as intake port shape must match. Larger bore sizes are for tuned/modified engines - fitting an oversize throttle body without proper tuning can hurt drivability.
