Oil Cooler Adapter Extension for VW Golf VR6 / TDI – High-Performance External Cooler Solution

This oil cooler adapter extension is specifically designed for the installation of an external oil cooler on VW VR6 and TDI engines. It ensures a precise and reliable connection between the engine block and the oil cooler cap, making it ideal for performance upgrades, turbocharged builds, and motorsport applications.

• Compatibility: Made for VW Golf MK3 / MK4 VR6 and various VW TDI engines
• Required: Must be used in combination with the appropriate aluminum oil cooler cap
• Material: High-strength, corrosion-resistant CNC-machined aluminum for perfect fit and durability
• Applications: Ideal for motorsport, turbo builds, track cars, and high-performance TDI setups
• Function: Extends and offsets the oil cooler port to allow clean and effective routing of external oil cooling systems
• Heat & pressure resistant – built to withstand extreme thermal and mechanical loads

Why use an oil cooler adapter extension?

On heavily tuned VR6 or TDI engines, oil temperatures rise significantly – especially with turbochargers or during aggressive driving. An external oil cooler provides better thermal management and improves engine longevity. This adapter extension provides the necessary space and alignment to install such systems cleanly, avoiding fitment issues with manifolds or turbo setups.

Installation note:

This adapter must be used together with a matching aluminum oil cooler cap. It mounts between the engine block and oil cooler housing. For proper sealing and fit, new O-rings and professional installation are strongly recommended.

Main advantages:

• Allows safe installation of external oil coolers on VR6 and TDI engines
• Perfect for high-performance builds, tuning projects, and motorsport use
• Made from durable high-grade aluminum – vibration and pressure resistant
• Helps reduce oil temperatures and increase engine reliability
• Precisely manufactured for easy, hassle-free installation

Note: Not compatible with engines that do not support the aluminum oil cooler cap. Please check fitment before installation.
