How many o2 sensors?

[StreetSoldier185]

This may be a dumb question but how many o2 sensors does the fourth gen have? i can only see 3....one in each header and one right before my cat....and which one would an o2 sim go on? Thanks

I wouldn't, your manifold o2s are pretty important when it comes to tuning, etc. They keep your air/fuel ratio in check.

uh, i disagree
I think it would be fine for him to replace his manifold o2 sensors with new ones. You are supposed to do it what, every 60,k miles?
Unless you have a valid reason?

I think he meant new O2s

you should have one after the cat and thats the one you want to use the sim on. i would get a casper electronic sim. we have a sticy over that product
