After looking at both im leaning more towards the MS for the reasons you said and i really dont wanna replace my harness.
Im also trying to research if using a aftermarket setup and tuneing it will give me the results i want.
Is there something that makes the spartan2 better then the Innovate WB? What is the easiest way to install the WB in the exhaust?
Can i replace a O2 with the WB sensor or do i need both O2's?
I hope the wb are placed before the cat convertersI was recently looking into WBs to replace my old one. So so many issues/complaints with all the Innovate's. I ended up doing dual 14point7 ADV 3 and they are very nice. My two replaced my rear O2 sensors on my car.
