This OEM-style throttle body from BUSIDN is engineered as a direct-fit replacement for multiple GM applications, carrying equivalent part numbers (12671379, 12659491, 67-3053, S20417, TB1271). Built from high-grade aluminum with ABS components and an integrated electronic actuator, it restores precise intake airflow control after a faulty or degraded original unit. The information below explains compatibility, installation considerations and the practical benefits you can expect from this replacement part.

Which vehicles and engines will this BUSIDN throttle body fit?

This throttle body matches several GM models and years that use 1.4L–1.6L inline-4 engines. Always verify the part number on your original throttle body before ordering to ensure an accurate match.

• Chevrolet Cruze L4 1.4L (2017–2019) and Cruze L4 1.6L (2019)
• Chevrolet Equinox L4 1.5L (2018–2020)
• Chevrolet Malibu L4 1.5L (2016–2020)
• GMC Terrain L4 1.5L (2018–2020)
• Buick Encore L4 1.4L (2016–2018)

How does this replacement compare to an original equipment unit?

The BUSIDN throttle body is manufactured to match the mechanical and electrical interfaces of the original part, enabling plug-and-play installation in compatible models. Materials include cast aluminum and ABS housings to meet durability expectations, while the electronic actuator replicates factory-controlled throttle operation.

• Includes common OEM part numbers for cross-reference
• Direct-mount design maintains original bolt pattern and connectors
• Aluminum construction resists corrosion and heat exposure

What should I know before installation?

Installation is straightforward for mechanically experienced technicians and DIYers comfortable with intake components and throttle calibration. After mounting, some vehicles require a throttle relearn or ECU reset; consult the vehicle service manual or a scan tool for exact procedures.

• Confirm your original part number matches one of the listed references
• Disconnect the battery and follow safety procedures before removal
• Perform throttle relearn/Electronic Control Unit reset if recommended

What performance or drivability differences can I expect?

Replacing a failing throttle body restores the throttle plate’s responsiveness and helps the engine maintain correct idle and acceleration behavior. While not a performance upgrade, a properly functioning unit contributes to consistent throttle response and smoother driving under normal conditions.

• Helps restore steady idle and consistent acceleration feel
• Reduces throttle hesitation linked to worn or stuck plates
• Ensures proper communication with engine control systems

Who is this for: The BUSIDN 12671379 throttle body suits vehicle owners and independent shops looking for a budget-conscious, direct-fit replacement for GM 1.4–1.6L engines. It is appropriate for those replacing a faulty factory throttle body, addressing throttle-related error codes, or eliminating idle and response issues. If you need exact fitment, double-check your vehicle year, engine size and the original throttle body part number before purchasing.
