AFR guage

power wire and ground and that's it. Make sure you install the bung at an angle so the condensation does not sit on the 02 sensor. Next your ready for tuning and then you have a peace of mind knowing how your motor is operating
That's what I wanted to hear. Will call Summit tomorrow and see if they'll match Ebag price.

I do run leaded race fuel on occasion, so it's gonna be tight where I weld the bung. Pretty sure I want it before the header evac tube. I measured my number 7 tube and it looks like about 34 or 35 inches. They suggest at least 36, if you run leaded fuel. Should be ok.
