Replace your old or worn engine cooling alternator fan with the EPS Upgrade fan. Our engine cooling fan features a unique hybrid fan blade pitch between the 911 and 964.

This upgraded design allows for increased airflow which improves cooling and engine temperature. Balanced, true, and made of high strength aluminum with a drop forged steel hub, this fan will far outlast the original magnesium fans from Porsche.

Remember, a damaged fan can cause premature failure of your alternator. Don't wait till it's too late.

EPS has manufactured an all aluminum precision injected molded upgraded replacement alternator fan housing for the 911. Our replacement fan housing is much more durable than its magnesium predecessor, and due to its precise manufacturing, you can expect a direct fit with no modifications needed.

The heat and vibration found in the engine compartment of an early 911 create a harsh environment, and the original Alternator Fan Housing often falls victim to its environment. The aluminum replacement Alternator Fan Housing from EPS offers better resistance to corrosion and longer service life than the magnesium original while providing superior electrical conductivity.

*NOTE: On 78-79 Porsche 911 SC you will also need to replace the fan to an EPS fan.
