A-Premium Electronic Throttle Body 6-Pin Plug — Direct-Fit Aluminum with Integrated TPS

The A-Premium Electronic Throttle Body with 6-pin plug is a direct-fit replacement that restores throttle response and supports engine control systems on select GM, Hummer, Saab and related models.

If your vehicle is showing rough idle, inconsistent acceleration, or diagnostic trouble codes pointing to the throttle assembly, this A-Premium electronic throttle body offers an OE-style solution. Built from aluminum and engineered to the same mounting and electrical specifications as factory units, it’s intended to match fitment and function on a long list of 4.2L, 3.5L, 3.7L and 5.3L engines. The unit includes the throttle position sensor and uses an electronic control design that works with modern engine management systems; idle air control is handled by the vehicle’s ECU, so a separate IAC motor is not included.

What vehicles will this throttle body fit?

This throttle body fits many GM-based platforms and allied brands produced in the early-to-mid 2000s. Verify compatibility by cross-referencing your part number or vehicle year, make and engine size before ordering.

• Chevrolet: Colorado (2004–2007), Impala (2006–2007), Monte Carlo (2006–2007), Trailblazer (2002–2007), Trailblazer EXT (2003–2006).
• GMC: Canyon (2004–2007), Envoy and Envoy XL (2002–2007), Envoy XUV (2004–2005).
• Buick, Hummer, Isuzu, Oldsmobile, Pontiac, Saab: Rainier, H3, Ascender, i-350, Bravada, Grand Prix, 9-7x across the specified years and engine displacements.
• Reference numbers covered: 12568580, 25312095, 8-12568-580-0, TB1022, ETB0075 and others for cross-checking.

How is this throttle body constructed and what are the key specs?

Manufactured with an aluminum housing and precision-machined bore, the assembly is designed for durability and consistent airflow. It carries an integrated throttle position sensor and uses a male pin-style electrical terminal configuration.

• Bore diameter: 3.03 inches for correct airflow matching.
• Terminal gender/type: male pin contacts; terminal quantity matches vehicle harness expectations.
• Materials: corrosion-resistant aluminum housing for long service life.
• Includes throttle position sensor; gasket and idle air control motor are not included.

Will installation require any special steps or recalibration?

Installation follows typical throttle-body replacement procedures, but many modern vehicles require an electronic relearn so the ECU can adapt to the new assembly. That relearn may be performed with scan tools or by following a vehicle-specific ignition/idle sequence.

• Expect basic removal and reinstallation using standard hand tools.
• Plan for a throttle-position or idle relearn procedure after installation.
• Verify electrical connector pinout and secure a clean mating surface; gasket not included.

What performance or ownership assurances come with this product?

A-Premium supplies this throttle body with quality control checks and a one-year unlimited-mileage warranty. It’s produced to closely match OE electrical and mechanical features to minimize installation troubles and help restore drivability.

• One-year unlimited-mileage guarantee from A-Premium for peace of mind.
