O2 sensor advice
Guys the guy who made my dump pipe made a big bung port. It's a large screw in port bigger than 20c piece.
Stock o2 sensor doesn't fit. Should I
A. Get the stock one fitted by exhaust shop by adding or modding the bung?
B. I thought about getting an aftermarket 4 wire that is screw in but have no idea. Bosch has universal ones but I guess I gotta check the size of the bolt. Is there issues if I cut and solder the Bosch universal 4 wire into the stock plug.
C. Some people said go wide and but if I install this can the car be driven or does it need to be tuned again
