OVERVIEW

This is the genuine Toyota port fuel injector for the FA20 and FA24 engines. Both engines use Toyota's D-4S system, which pairs four direct injectors with four port injectors. This part is the port injector, which sprays fuel into the intake runner and helps keep the intake valves clean. Clogged or failing port injectors cause rough idle, misfires, lean codes and hesitation at light throttle. The engine uses four, and replacing all four as a set keeps fuel delivery even across the cylinders. This part does not replace the direct injectors.

FEATURES

• Genuine Toyota Part: The factory port injector, with exact factory flow, spray pattern and fit.
• Built by Denso: Made by Denso, the original equipment manufacturer of this injector.
• Shared Platform Part: The same injector is used on the FR-S, 86, GR86 and both generations of BRZ.
• No Tuning Required: Stock flow rate, so it installs on a stock ECU calibration.
• Direct Replacement: Plugs into the factory harness and fuel rail with no modification.
