This Hitachi throttle body features a 75mm diameter throttle bore, which allows for efficient airflow and improved engine responsiveness. The OEM-style electrical connectors make for easy installation, ensuring a hassle-free replacement process. The SX-4128 Throttle Body is a direct fit for your Toyota Tundra, requiring no modifications to your vehicle's existing fuel injection system.

3. Performance: The throttle body can help improve your engine's performance by optimizing airflow and fuel delivery.

4. Long-Lasting: OEM parts are usually built to last, providing durability and longevity.

1. Price: OEM parts tend to be more expensive compared to aftermarket alternatives.
