the 4 wire should work fine, it'd be perfect if it had the same slots in the tip but i don't think it's critical, some of the sensors that are in the crotch where the two pipes come together instead of having the common 4 slots on the sides of the tip, have a hole in the end of the tip and vent holes around the base for better flow through the sensor as it's pointing at the gas flow instead of the gas hitting the side of the sensor tip
all america wants is cold beer warm cat and a place to take a poop with a door on it
