vette o2's vs. extensions
 

well as it read, which in yall's opinion is better denso vette rears vs extensions with either new denso's for my car or my over 100k stockers that work just fine , this is for my longtube header install thanks guys all opinions appreciated!

i would say just get the vette o2s.. thats what im runnin.. no probs.. i believe u can possibly pop a code for o2 heaters with extensions.

well how long have u had them on and what brand are u using?

I got O2 heaters code on both vette O2s and w/ stock O2s and extensions.

^ If you are still running with stock tune, there is a flash calibration to correct false heater codes.

To the OP, buy the Corvette sensors. Your 100K sensors probably aren't switching as fast as they did when they were new. I'm sure extentions work, but they are another connection that could eventually fail.

No stock tune. I don't know what calibration you're talking about however I know you can tune out the error code. With that you're still not fixing problem.

vette o2s, have the slow switching/heating codes deleted
