Best O2? Heated or 1-wire?

[Warp6]

Is there a definite answer to which sensor type is best?

All new cars have heated, and last a lot longer. Just the expense is the downside I guess.

I've been looking for a heated leadproof o2 kit if anyone has seen them.

Caspers sells the heated kits. I would buy you a Denso O2 sensor, alot cheaper.

I have run heated O2s and currently have a one wire Denso. I was just curious if there's a definite proven advantage from one to the other.

We've always used the Casper's heated sensor kits. John has used various sensors over the years. I've never had one fail. We use ME16s now, so even if the sensors fail I'm not sure I'd care. We have EGT on the race car. The street car uses unleaded. It's all good. I never understood the guys who say heated sensors suck, but are content to keep pouring in OEM sensors at however many bucks each every time they turn around. Sounds like dogma to me. Whatever.
