Electronic Throttle Body for Chevrolet Silverado 2006-2008 - Direct

In this review the focus is a direct-replacement electronic throttle body designed for a range of GM V8 vehicles from the mid 2000s. The bottom line: this unit is aimed at owners who need a reliable, OEM-style replacement that restores throttle response and idle control without complicated modifications. The reviewer found it to be a solid, easy-to-install option for Silverado, Sierra, Yukon, Escalade and several other models, delivering the primary benefit of fit and function for those swapping a failing factory part.

Key Features

• Vehicle compatibility: Covers many GM models and years so buyers can match the unit to Silverado, Sierra, Yukon, Escalade and related vehicles with the specified V8 engines.
• OEM replacement numbers: Replaces common OE part numbers such as 12580760 and 12679524, simplifying parts matching for repairs.
• Material and finish: Aluminum alloy housing with a gray and black finish offers a durable, corrosion resistant body for long service life.
• Integrated sensors: Includes a throttle position sensor and a six-pin female blade connector for plug-and-play electrical connection on compatible harnesses.
• Fuel efficiency benefit: Designed to maximize airflow efficiency which can contribute to improved combustion and better fuel economy when installed correctly.
• Build quality: Reinforced, heat-resistant materials provide abrasion and corrosion resistance for extended durability under engine bay conditions.

Who It's For

This part is best for owners or independent shops repairing mid 2000s GM trucks and SUVs with 4.8L, 5.3L, 6.0L or 6.2L engines who need a direct-replacement throttle body that matches OE mounting and connector style. It suits drivers who want to restore proper idle control, throttle response, or who have a throttle body fault code and want a reliable repair.

It is less appropriate for vehicles outside the listed model years and engines, or for anyone seeking a performance-modified throttle body with larger bore or custom tuning features. Buyers who need dealer-level calibration services should verify compatibility with their vehicle before purchase.
