SSi HVAC Heater Control Unit Housing

SSi HVAC Heater Control Unit Housings for Classic Porsche

When it comes to restoring or maintaining the cabin climate system on a vintage Porsche, few components are as overlooked — or as critical — as the heater control unit housing. This small but essential part serves as the structural enclosure for the heater control mechanism, directing warm air flow into the cabin and providing the mounting framework for the control cable and associated hardware. On classic air-cooled Porsches, these housings are directly integrated into the heat exchanger system and are subject to the same harsh conditions: road salt, condensation, exhaust heat, and decades of thermal cycling.

SSi has been a trusted name in Porsche specialty parts since its founding in California in 1976. Originally a U.S. company, SSi became part of the JP Group a/s family of brands in 2013, joining the same parent as the well-known DANSK exhaust line and moving production to Denmark. This heritage informs SSi's approach to every part they manufacture: a commitment to OEM fitment, durable materials, and the specific needs of Porsche enthusiasts who refuse to compromise on quality.

SSi's HVAC Heater Control Unit Housings are purpose-built for classic Porsche applications, including the iconic 911, 912, and 930 model lines spanning the 1960s through the late 1980s. These housings are designed as direct OE-style replacements, meaning they cross-reference directly against original Porsche part numbers and drop in without modification. Notably, SSi's heater components are constructed from stainless steel — a meaningful upgrade over the original parts, which were notoriously prone to corrosion from moisture, salt, and exhaust-related grime buildup.

The original heater control boxes found on air-cooled Porsches were a well-documented weak point in the climate system. Salt, condensation, and water caused them to rust prematurely, and finding quality replacements became increasingly difficult as the cars aged. SSi stepped in to fill that gap, offering properly engineered housings that restore the integrity of the heater control assembly and support the full range of ancillary components — including gaskets, clamping bolts, and control cables — needed for a complete repair.

Whether you're executing a full rotisserie restoration on a numbers-matching 911 or simply replacing a failed component on a well-loved daily driver, SSi's heater control unit housings provide the fit, finish, and durability that Porsche owners expect. Their OE cross-reference compatibility makes parts identification straightforward, and their construction from quality stainless steel means the repair is likely to outlast the original component by a significant margin.
