O2 Sensor - possible cheap replacement??
Does anyone know if these would work properly and how difficult they would be to install? Thanks.

That one is a universal 3 wire O2 sensor. As long as the original O2 is a 3 wire, it will work great. You’ll have to reuse the existing wire connector and it requires a little bit of splicing.
If you want to go even cheaper, you can replace the 3 wire with a single wire O2. The only differences are the 2 heater wires. The signal wire is the same. The heater wires are only there to heat up the sensor during a cold start. This will make the engine a little more environmentally friendly before the exhaust gases have a chance to bring the O2 sensor up to operating temperature. Essentially the heater is a more or less useless option.

Do we use a three wire O2 sensor (the S4's)? Are most of the Bosch O2 sensors the same but with different connectors? If so, does anyone know the Bosch part number of an O2 sensor that we can splice into our cars that will work properly? I think the Bosch OE number is 13918 and the Bosch universal is 15735 but are there others that will work and be less expensive? Thanks.

Anybody know what to do with the 4th wire if you get a 4-wire? Just ground it to anything?

So in essence, a 3 wire is the same as a 1 wire except is has a heater. The signal is processed the same way for both sensors. The 4 wire ones are totally different from the 1 and 3....... and the 5 wire (Wide Band) are even more different that all of the other ones.

Hmm... I thought I'd read on Bosch's site that 1 wire is signal (grounded to exhaust), 2 wire is signal and ground, 3 wire is 1 wire plus heater, 4 wire is 2 wire plus heater.

You wouldn't happen to have any ideas on the Boxster ones, would you? It's a 3-wire too so would it be the same size threads, etc. as the 928?
Thanks for the fantastic info Garth!
