TF035HM Turbocharger | OEM 49135-07850

Product Overview:

This is a TF035HM turbocharger from Mitsubishi Heavy Industries, engineered to OEM specifications for the Roewe W5’s 1.8L turbocharged 15S4G engine. Using VGT (variable geometry turbine) technology, it optimizes boost pressure across the RPM range, delivering consistent power output (rated around 162 PS) and helping restore factory throttle response and fuel economy for vehicles suffering from turbo lag, power loss, unusual noise, or a fully failed unit.

Key Features:

• OEM-Matched Fitment: Manufactured to match the mounting configuration and flange dimensions of the original 49135-07850 turbocharger for a direct bolt-on replacement.
• Genuine MHI TF035HM Platform: The factory-fitment turbo design used specifically on Roewe’s 15S4G 1.8T engine.
• VGT (Variable Geometry Turbine) Technology: Adjustable vane positioning optimizes boost delivery across the RPM range for smoother, more responsive power.
• High-Grade Turbine Wheel Material: K18 material turbine wheel construction for durability at extreme operating temperatures (up to 950°C).
• Water-Cooled Bearing Housing: Improves thermal management and extends service life versus air-cooled designs.
• Restores Lost Power & Efficiency: Addresses common failure symptoms — reduced power, whistling noise, boost leaks, and check-engine codes.
• Recirculation Valve Available Separately: A matching boost recirculation valve/diverter valve service kit is available for this turbo model if only that component needs replacement rather than the full unit.
• Warranty: Typically 1-year manufacturer warranty (confirm specific terms with your supplier/listing).

Before You Buy:

Please confirm the part number stamped on your original turbocharger (49135-07850 vs. the closely related 49135-07870/07880/07970/07971/07980 variants) against your Roewe W5’s exact production year, since these numbers represent a family of closely related but distinct revisions. Let us know your vehicle’s VIN or engine serial number if you’d like help verifying exact compatibility before ordering.
