Rock auto shows two part numbers for oxygen sensors...which one is good for the SC? Does it vary by year? I'm currently looking for sensors for my 95 chameleon.

The numbers from rock auto are DY703 or DY698.

Thanks folks!

scratch that, I found the answer.

DY703 is the SC-specific O2 sensor.

DY698 is for n/a 3.8L cars.

Do they share the same lead length?

Do they share the same lead length?

I want to say yes because the motorcraft website doesn't list distinctions between pass and driver side. I also recall the only time I had to worry about lengths was when I had to get 02 sensors for a set of kooks headers, but even then it was the same length for both sides (just longer than stock).

if you hadn't bought them yet you may want to consider some ntk's
they last a little longer than the bosch
