I must argue this point though Will! I've been using a Bosch O2 Sensor in my 92 EGRLess for about two years now w/o any ill effects too. Now granted, it may be because it IS
an EGRlesss engine & that this engine runs hotter than any other NA 3800 too. Maybe it'* got to do with how much heat the engine puts out throught the exhaust? I know this is true in most Fords, as their CATS are hotter than just about anybody others I've found. I know too my exhaust is quite hot due to the CAT removal too & a straight pipe installed in it'* place. Just something to think about.....
