WAI ETBW237 Electronic Throttle Body Assembly

The WAI ETBW237 is a direct-fit electronic throttle body (ETB) designed to restore proper engine airflow management and throttle response. WAI Global manufactures this unit to meet OE form, fit, and function, making it a reliable replacement for a worn or failed original throttle body.

The electronic throttle body is a critical component of the Electronic Throttle Control (ETC) system. It regulates the volume of air entering the engine by opening and closing an internal butterfly valve in response to signals from the Engine Control Module (ECM), replacing the traditional mechanical cable linkage with precise electronic control.

Key Features:

• Direct OE replacement — engineered to match original specifications for a straightforward installation
• Integrated throttle position sensor (TPS) for accurate real-time feedback to the ECM
• Internal butterfly valve and bore sized to OEM specification for proper airflow
• Built-in return spring ensures fail-safe throttle closure
• Compatible with OEM wiring harness connectors — no modification required
• Supports factory cruise control, traction control, and stability control integration

A failing throttle body can cause rough idling, hesitation, poor acceleration, and illuminated check engine lights. The WAI ETBW237 restores proper throttle calibration and engine performance to OE standards.
