Electronic Throttle Body A Premium Aluminum 6‑Terminal for Chevy GMC

Description

Product Overview

The A Premium electronic throttle body is engineered to provide a direct, responsive link between the accelerator pedal and the engine’s air intake system. Built from high‑grade aluminum, the housing offers a balance of strength and lightweight performance, reducing overall engine mass while maintaining durability under the high‑temperature conditions typical of modern powertrains. The internal throttle plate is precision‑machined to match OEM specifications, ensuring a seamless fit and function when installed as a replacement part.

Measuring a 2.56‑inch bore diameter, the throttle body delivers accurate airflow measurement across a wide range of engine speeds. The integrated throttle position sensor (TPS) communicates real‑time position data to the engine control unit (ECU), enabling fine‑tuned fuel delivery and ignition timing. Six female blade terminals provide a secure electrical connection, simplifying installation and reducing the risk of wiring errors. The design incorporates a flange‑mounting style that aligns with factory mounting points, allowing for a bolt‑on replacement without the need for custom brackets or adapters.

Compatibility is a core strength of this product. The part number APTHB040MF is cross‑referenced to a broad list of OEM part numbers, including 977‑315, 67‑3014, S20015, TB1033, and many others, covering a range of Chevrolet, GMC, Buick, and Pontiac vehicles equipped with the 2.4‑liter L4 engine. This extensive fitment ensures that owners of 2008‑2012 model year vehicles can rely on a single part to address throttle body wear, sensor failure, or performance degradation.

Beyond the mechanical and electrical specifications, the throttle body is designed with a gray and black finish that resists corrosion and matches the aesthetic of factory components. The internal surface is treated to minimize friction, promoting smoother throttle plate movement and extending the service life of the assembly. Each unit undergoes rigorous quality testing to verify voltage tolerance up to 5 volts, temperature resistance up to 205 °C, and measurement accuracy comparable to original equipment manufacturer (OEM) standards.

Usage

This throttle body is ideal for both daily drivers and performance‑oriented enthusiasts seeking to restore or enhance engine response. In everyday commuting, the precise airflow measurement helps maintain optimal fuel efficiency, while the rapid throttle response reduces lag during acceleration, providing a more engaging driving experience. For performance applications, the accurate TPS feedback enables aftermarket tuning solutions to extract additional horsepower without sacrificing reliability.

Installation is straightforward for qualified technicians or experienced DIY mechanics. The flange‑mount design aligns with existing bolt patterns, and the six‑terminal connector plugs directly into the vehicle’s wiring harness. No additional drilling or modification is required, minimizing installation time and reducing labor costs. The lightweight aluminum construction also contributes to a modest reduction in overall engine weight, which can be beneficial in vehicles where every kilogram matters.

Because the throttle body is built to withstand high temperatures, it performs reliably in a variety of climates—from hot desert environments where engine bay temperatures can exceed 120 °C, to colder regions where rapid warm‑up is essential for emissions compliance. The part’s durability ensures long‑term operation without frequent replacements, making it a cost‑effective solution for fleet vehicles, ride‑share cars, and personal automobiles alike.
