Does anyone knw if I can fit 98 automatic base prelude 02 sensors on a 97 type Sh 5speed ???

 

I assume that you can, but look around and check out part numbers for both. If you can't find it, call Honda.

 

You should be fine using them, the computer will adjust to the new o2 sensors.

 

X2 on what 1G said, can't go wrong if you cross-reference the numbers. Places like NAPA and RockAuto have online cross-reference of parts (I prefer RockAuto) or you could call Honda, they should be able to answer that. If they're anything like the 4th gen ones be prepared to shell out $80+ for a new one (crazy, right?).
