From my experience with Bosche O2's a 5 wire is a wide band unit while a 4 wire is not. I've used the 5 wire in some of the turbo cars I've built in the past in order to log the air fuel to tune AEM and other stand alone ecu's with.
Bosche also make "universal" 4 wire O2's that come with a good length of wire that I might give a try. You just connect your plug to the new O2 wire with the supplied splice connector. I've used them in everything from BMW's to Honda's with great success.
Partsgeek.com has them for the up and down stream for most years boxsters. Prices are $44-$64.

I had planned to use the universal sensor, but have read some problems on Porsches. I don't know how true they are, but its only 100.00 ea for the bosch plug and play ones that are boxster specific. I can't imagine the heater issue being a big concern, but I am trying to cover all of the bases.
