One of the most important pieces of the air-cooled Porsche's engine is the fan. This fan has the power to suck tremendous amounts of air past the various cooling fins, keeping the air-cooled car from blowing its head—both literally and figuratively.

After more than a quarter of a century of duty, the one on our 1984 Porsche 911 Carrera was looking a bit dingy. In addition to air, that fan also sucks in a ton of grime.

Some owners go whole-hog and polish the fan as well as its cast housing, but we decided to keep things stock-looking. Both parts simply spent some time in the bead blast cabinet. Since the center section of the fan itself is cadmium plated, we masked off that section with some aluminized duct tape.

The light coating of grease was simply blasted away, leaving us with two pieces that look nearly new. Like our valve covers, these should age nicely.

A side note about these fans: We had been told that they were no longer available from Porsche, but looks like they're back in stock.
