- Temperature-resistant silicone seal
- Validated with 200+ hours of vibration testing and 1000+ hours of extreme heat and cold operational testing, plus on-vehicle testing
- Sealed ball bearings limit airflow leakage and reduce mass air-flow reading errors
Quick facts
- Part: Standard Ignition S20121 fuel injection throttle body
- Fits: 2001-2003 Lexus ES300 V6 3.0L
