Porsche 928
1978 – 1995 A/C Compressor Load Reduction Relay
Additional 1978 – 1986 Auxiliary Fan ON with A/C On
• Three Products Offered:
1. 16 Valve Engines: 1978 – 1984 & 1985 – 1986 Euro: $225 + shipping
2. 32-Valve 1985 – 1986: $225 + shipping
3. 32-valve 1987 S4/GT – 1995 GTS (A/C Head Relay Load Reduction Only): $195 + shipping

Compressor Relay Load Reduction = Longer Internal A/C Control Head Relay Life
- Don’t wait for the internal relay to fail
- Reduced current load (high current flows through kit’s external relay)
- Higher voltage at compressor clutch due to reduced length of circuit wiring (less voltage drop).

1978 – 1986 Auxiliary Fan ON with A/C On keeps engine cooler and increases A/C cooling in many cases.

1987 and newer 928s have dual electric fans electronically controlled to increase cooling capacity as needed for A/C and engine cooling, so no additional features are required.
