Have read a few posts in the archives about upgrading from a three to a late-model six bladed fan for better cooling, and it wasn't clear to me at what point Porsche switched from the three to a six on the 944. Does anyone know which years have the six?

 

Cars with the late interior.

It's worth it.

 

So '85.5 and newer?

 

i put them on an'84na, fans/shroud.

87951

 

I did the swap for reduced noise. I'm not sure if they really cool any better than 3 blade...

 

I have one for sale if interested
