Description
Built for U.S.-specific Porsche 911 3.0L conversion applications, this SSI stainless steel heat exchanger set includes both the left and right heat exchangers. This version is made with 15mm exhaust flanges and is intended for U.S. 3.0L conversion setups from 08/1979-07/1983 production.
Made from stainless steel, these heat exchangers offer improved corrosion resistance compared with standard mild steel exhaust components. They are a premium choice for Porsche 911 exhaust and heating system service where stainless steel construction, heater function, and the correct flange thickness are required.
Important Fitment Note: This is the U.S.-specific conversion version with 15mm flanges. For Euro-specific applications requiring 8mm flanges, use the correct 8mm flange version instead. Always confirm market version, engine size, production date, flange thickness, exhaust layout, muffler compatibility, and heater ducting before ordering.
