The premium-quality air distribution housing with evaporator core (HVAC component) designed for Porsche vehicles. This unit is part of the heating, ventilation & air-conditioning (HVAC) system that directs cooled air from the evaporator into the cabin and supports climate control performance.
The air distribution housing with evaporator receives refrigerant-cooled air from the A/C system and routes this conditioned air into the vehicle cabin. The integrated evaporator cools and dehumidifies incoming airflow before it travels through ducts and vents. This ensures efficient cooling performance and contributes directly to occupant comfort, especially in warmer conditions.
• Application: Center-mounted air distribution and evaporator housing unit in the HVAC system (right-hand drive cars in many listings). It replaces the original Porsche part 99657390101 and is designed to fit directly into the factory climate control assembly.
• Function: In operation, the evaporator core inside the MAHLE housing absorbs heat from the incoming cabin air as refrigerant circulates through it. The housing channels this cooled air through the HVAC blower and into the passenger compartment at controlled rates. A quality housing ensures proper fitment, stable mounting of the evaporator core, and reliable airflow distribution - all critical to effective climate control.
An air distribution housing and evaporator assembly that is worn, clogged, cracked, or inefficient can result in:
• Reduced cooling performance or inability to reach target cabin temperatures.
• Moisture buildup or odours as the evaporator becomes less effective.
• Higher HVAC system strain, leading to increased wear on blower motor or compressor.
Replacing this component with a MAHLE-quality HVAC housing restores airflow integrity and cooling efficiency, helping maintain occupant comfort and system reliability.
Consider replacing if you notice:
• Weak or inconsistent A/C airflow
• Unusual noises from the HVAC box
• Reduced cooling or warm air output
• Refrigerant or moisture leaks around the housing
• During major climate control servicing

The Rennline HVAC control panel is CNC milled from a billet aluminum block and anodized for a classic and elegant dash upgrade. Whether you're trying to clean up the dash on your early 911, or backdating the dash on your G-body car, these HVAC controls are sure to do the job. Featuring simplified markings and updated micro LED indicators, the unit pairs very well with our I12 Billet HVAC Knobs (not included but available separately). OEM plastic units are prone to scratching and fading, while these units are proven to stand the test of time. Installs easily to factory control mechanism.
Note: If installing in a 74-89 car, the dash must be backdated as these controls are smaller than the later controls.

What This Product Does
The clamp retains the water drain sleeve at its connection within the ventilation assembly. It is retaining hardware for the drainage connection, rather than a heater coolant hose, blower or fresh-air housing.
Functions
- Holds the drain sleeve at its attachment point.
- Supports reassembly of the ventilation drainage connection during repair or restoration.
Technical Details
- Product identification: 99951214502.
- Brand: OE Match.
- Component: hose clamp for the water drain sleeve.
- Assembly context: ventilation and heating system.
- Diagram position varies with model and production period.
Symptoms of Fault
Inspect the clamp if the sleeve is loose or there is seepage around its connection. Check the sleeve and adjoining fitting too: damage to either can require attention independently of the clamp.
Why Replacement Matters
A damaged or corroded clamp may no longer retain the sleeve correctly. Renewing defective retaining hardware allows the connection to be secured during reassembly. OE Match focuses on Porsche replacement applications, with specification checks and sample evaluation forming part of its development process.
FAQs
Should a corroded clamp be renewed?
Replace it if corrosion or damage prevents correct fastening. Inspect the adjoining sleeve before reassembly.
How should compatibility be checked?
Compare part number 99951214502 with the original component and confirm the vehicle application. The diagram references identify different positions for this clamp across the listed assemblies.
