Description
Built for Porsche 911 performance and custom conversion applications, this SSI stainless steel heat exchanger set includes both the left and right heat exchangers. This version features 41mm outside inlet tubing and is intended for Porsche 911 models using a 964 / 993 3.6L engine conversion setup.
The stainless steel construction provides improved corrosion resistance compared with standard mild steel exhaust components, making this set a strong choice for high-performance custom builds, engine conversion projects, and long-term exhaust system service.
Important Fitment Note: This heat exchanger set is for Porsche 911 applications with a 964 / 993 3.6L engine conversion. Major modification to the engine tinware is required when installing on 3.6L engines. This is not a standard bolt-on replacement for original engine configurations. Always confirm engine conversion details, exhaust layout, inlet size, tinware clearance, muffler compatibility, heater ducting, and required fabrication before ordering.
