Aluminum Cooler Thermostat Bungs for BMW E46 3 Series

Upgrade and safeguard your BMW with this Aluminum Cooler Thermostat Bung Adaptor, precision CNC machined from a single aluminum billet for durability and a precise, race-ready fit. Designed for diesel engines, it replaces faulty parts rather than the entire system, helping you keep your car on the road with minimal downtime. This adaptor is tailored to fit a wide range of BMW models and engine codes, ensuring a secure, reliable connection where it matters most.

Key benefits include temperature management that supports more efficient airflow and helps prevent inlet and turbo clogging, contributing to consistent performance in demanding conditions. The silver, corrosion-resistant finish not only looks the part but also stands up to the heat and vibration of daily driving and track sessions alike.

All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.

Benefits & Tips

• Use on diesel BMWs to help reduce inlet air temperatures and protect turbo components, potentially improving throttle response.
• Ideal as a maintenance upgrade when replacing aging or faulty inlet plumbing—focus on the adaptor, not the entire system.
• DIY-friendly upgrade for skilled installers; professional installation is highly recommended and no installation guidance is provided.
