Eisenmann Stainless Heat Exchanger Set 38mm - Porsche 911 F-Model / Carrera 2.7

Factory 911 heat exchangers were mild steel, and most have rotted through by now. The Eisenmann Stainless Heat Exchanger Set replaces them with stainless units that will outlast the car, with a 38mm header diameter for stock and mildly built engines.

Cabin heat works as designed, and the flat-six breathes better.
