04 Cobra's w/Prochamber come in please.

[Speednut]

I search but theres no answer that i found I am installing the o/r Prochamber w/ stock headers, and I know I need the MIL eliminators but do I need the 02 Extensions?

 

[GetBitBiatch]

you shouldn't need the O2 extensions. you only need those if you are going to be using long tube headers

 

[DitchTehFish]

I'm pretty sure you do need them considering you have an 04.

 

[adamb258]

yup 04 guys need 'em

 

[HPCobra04]

I just got mils and I was perfectly fine

If the MIL's and 02 sensor wires are long enough you may not need the extensions for the rear. The front 02 sensors you will be fine with, they need nothing.

u do need the O2 extensions, had the MAC o/r h pipe and the back two inputs where the O2 sensors go are way back near the beginning of the catback exhaust so you need the extensions to reach em or else youre cars going to have the check engine light on all the time. and that shit gets annoying. my car ran real lean also with the o/r h pipe might need a tune maybe?
