After many failed sensors. I now use a spark plug anti fouler ( 18mm x 1.5 thread )from the HELP section at the auto parts store, weld one into the left and right collectors and be done. This will prolong the life of the sensor,as it keeps water/ moisture from hitting the ceramic cell. and has no effect on afr accuracy.



This might be true if you are using a bosh type sensor but a true NTK sensor needs to be in the stream the correct depth. The sensors are killed by the lead in the fuel which attaches to them. The sensor should be mounted high with its face mounted downn in a way to not let moisture sit in it.
