roduct Overview:

This is a TD04L6 twin-scroll turbocharger from Mitsubishi Heavy Industries, engineered to OEM specifications for GM’s 2.0L LTG turbocharged Ecotec engine used across a wide range of Buick, Chevrolet, and Cadillac models. It restores factory boost pressure, throttle response, and power delivery for vehicles suffering from turbo lag, power loss, unusual whining/grinding noise, oil leaks, or a fully failed unit — common wear points as these engines reach higher mileage.

Key Features:

OEM-Matched Fitment: Manufactured to match the mounting configuration and flange dimensions of the original 12688476 turbocharger for a direct, no-modification bolt-on replacement.
Genuine MHI TD04L6 Twin-Scroll Platform: The factory-fitment turbo design used across GM’s 2.0L LTG engine lineup, known for a strong balance of daily-driving reliability and boost response, manufactured by MHI in Japan.
Twin-Scroll Design: Separates exhaust pulses from different cylinder banks for improved spool response and reduced turbo lag versus single-scroll designs.
Complete, Ready-to-Install Unit: Supplied as a full turbocharger assembly for direct replacement.
Restores Lost Power & Efficiency: Addresses common failure symptoms — severe power loss under acceleration, blue/white exhaust smoke, and unusual turbo noise.
Broad Multi-Brand Coverage: A single turbo model supports numerous Buick, Chevrolet, and Cadillac vehicles sharing the LTG engine, useful for sellers serving diverse GM-platform customers.
Warranty: Typically 1-year manufacturer warranty (confirm specific terms with your supplier).

Before You Buy:

Please confirm the part number stamped on your original turbocharger (12688476 vs. the closely related 12682937/12663028/12649944/12653326/12658628/12674684 family) against your vehicle’s exact model, trim, and production year, since GM’s LTG 2.0T turbo applications span many badge-shared vehicles with closely related part number variants. We also recommend diagnosing the root cause of any prior turbo failure (e.g., oil supply issues) before installation, and recommend professional installation. Let us know your vehicle’s VIN if you’d like help verifying exact compatibility before ordering.
