i think i may have a problem. i have bbk long tube headers and the o2 sensor when i unplug it the female end is at the top of my trans. do i need extentions for o2 on the fronts? i dont think the o2 sensors will work and im very fusterated. answer quick please

01BlueCobraVert

you need extensions for the front O2's

i have rear o2 extentions and mil eleminators do i need front o2 extentions

JimboGT01

I thought that if you have a tuner you can turn them off?
Do you still have to put them in after doin the LT's?

01BlueCobraVert

You can turn the rears off. The front ones control the A/F ratios

01BlueCobraVert

Did you actually need them on the rear ones? I have my BBK's going on and I purchased the extensions only for the front.

Yeah, I'm pretty sure you will need 02 extensions.

5speedstang

you only need 02 extentions for the fronts the mil eliminators make a resistance for the rear 02s that tells the comp that they are running fine. just long tubes i am finding out are a pita

lt's are on their way. i ordered steeda o2 extensions, i am going to turn off the rears with the sct. will there still be a hole in the exhaust were the rear o2 sensors are supposed to go?

thats pretty half fast pfftt BBK... ever since i got the BBK xpipe i could wait to get that junk off my car.....I always hated BBK, they so cheap and dont even include everything needed, the headers should have come WITH extensions
