• OD 42mm, ID 39mm (OE version ID 29mm) for better flow
• Aluminum vanes inside for improved heat transfer
• Comes with loose flange for welding to sports exhaust
• Lightweight inner coils for optimal heater output

This high-performance heat exchanger (left side) is designed to improve the efficiency of your engine while maintaining good heater output. Featuring an OD of 42mm and an ID of 39mm (compared to the OE version’s ID of 29mm), the larger tubing reduces restriction and enhances airflow, making it ideal for high-performance motors.

Inside, the aluminum vanes promote superior heat transfer, while the lightweight inner coils ensure that the system can still produce effective cabin heating. The heat exchanger also comes with a loose flange for easy welding onto a sports exhaust (sold separately), making it a great choice for performance upgrades without sacrificing comfort.
