Focus Central 2 piece (even 3 piece if you can find one) is generally accepted as the standard, however people have reported the Ford Racing/Esslinger pulley to be good as well. Personally, I have the FC set waiting for a nice warm day in April to go in.

Very very much agreed. I've also heard of people having problems with the FC 2 piece with their A/C in summer, overheating the car.

I had the AFX on for 8 months now without any charging or cooling issues. I had a bunch of mods done all at once so can't say how much the UDP alone contributed but it is much better than before.

Overheating the car : the engine is too hot or the A/C is throwing hot air inside ???
(usually I speak french :D)

If I don't have A/C, it won't change anything for me ...

Its an underdrive pulley, it makes the water pump, alternator and a/c compressor turn less than normal.

I have the FC one for 2-3yrs now, still having the same battery. I will say just get whatever brand you like, they're almost the same.

I have a 2 peice Focus Central and I am actually taking them off and putting the stock ones back on. There was a big diff.

I never use my A/C anyway though. Even on +40 days. I miss heat :(. The fealing of touching a super hot shift knob. So hot in the car your back sticks to the seat. AHHHHHHHHHHHHHHH come back summer!!!!!!!!!!!!!!!!!
