Electric Throttle Body 12601387 Fit Chevy Silverado Tahoe Escalade

In this review of the Electric Throttle Body 12601387 the bottom line is straightforward: it is a practical replacement for owners of late-model GM V8 trucks and SUVs who need a direct-fit electric throttle body that restores throttle response and can improve fuel economy. The reviewer finds this unit best for technicians or DIY mechanics working on Silverado, Tahoe, Suburban, Express, Avalanche, Camaro and Corvette models from the listed years because it replaces common OE numbers and installs without major modification.

Key Features

• Vehicle Compatibility: Covers a wide set of GM V8 applications so owners of Silverado, Tahoe, Escalade and other listed models can find a matching fit.
• OE Replacement Numbers: Replaces OE part numbers like 12601387 and 12629992 to simplify ordering and reduce compatibility guesswork.
• Aluminum Alloy Housing: The alloy housing offers corrosion resistance and helps the throttle body maintain structural integrity under engine bay heat.
• Integrated Throttle Position Sensor: Includes the throttle position sensor so you get the sensor feedback needed for stable idle and ECU control without sourcing extra components.
• Easy to Install: Designed for a direct bolt-on installation on supported models, which reduces labor time for routine replacement.
• Improved Airflow Efficiency: The design aims to maximize airflow and combustion efficiency, which can contribute to better fuel economy over time.

Who It's For

This throttle body is aimed at owners and mechanics of Chevrolet and GM V8 vehicles from approximately 2009 through 2015 who need a like-for-like replacement. It is most useful when the original throttle body shows wear, erratic idle, or when a failed throttle actuator triggers check engine codes.

Those who should look elsewhere include owners of vehicles outside the listed engine sizes or years, and anyone who requires a performance or aftermarket high-flow modification beyond OEM-equivalent parts. For extensively modified engines, a dedicated performance throttle body would be a better choice.

Pros & Cons

Pros

• Direct replacement for multiple OE numbers, making fitment straightforward for many GM V8 models.
• Aluminum alloy construction and included throttle position sensor add durability and convenience.
• Many customers report good value, easy installation, and restored rpm stability after fitting.

Cons

• Some users reported mixed long-term reliability, with a few failures after months in service.
