VCTR Performance BMW B48 G-Series Oil Cooler Kit

Overview

The B48TU platform builds oil temperature quickly under sustained hard use or in warm ambient conditions. This oil cooler kit adds an additional heat exchange circuit to keep oil temperatures more stable during performance driving.

Why Upgrade?

• Improved oil temperature management for the B48TU under sustained load
• Reduces thermal stress on engine oil during hard driving
• Complete kit — all required fittings and connections included
• Wide G-series B48TU platform fitment

Engineering Focus

Complete oil cooler kit for B48TU applications across multiple G-series chassis. Includes oil cooler core and all lines and fittings for installation.

Built for the Drive, Not Just the Dyno

Oil temperature is the metric a track day actually punishes — a hot lap is fine, three hot laps back to back is where the factory cooling system runs out of margin. A dedicated cooler is cheap insurance against the kind of thermal stress that shortens an engine's life long before it shows up as a power number.
