As the title says, who can tell me what is the O2 I want for my 98 LS1? It's been running pretty crappy after the tune. I dynoed at 390 on a Mustang Dyno. Seems to run great under WOT but "misfires" at lower RPM's. My mileage is only around 19 mpg.

Thanks!

I have had good luck with the bosch 13111's, also they are longer so no need for the o2 extensions.

Go with NGKs. I had bad luck w/ Bosch/Densos/Delcos.

Denso o2 sensors are the best in my opinion if you get the ones for the corvette rears the cord length is like 44 inches or something ridiculous. This is what i run on my car they work great.
