Toyota 3S engines use a pentalobe style security bit for securing the IACV (idle air control valve) actuator to the throttle body. To clean and adust this small part you need the correct size bit. We sell the entire kit in an 8pc set, although the 3S engine only requires one specific size.
- Fine-tune your idle speed on 3S Gen4/5 engines
- Clean sticky IACV valves
