I didn't know they made them, but i have used their plugs for years with no problems. Seems like a good product based on my usage with spark plugs but I don't know anything about their 02's? Anyone using them with luck?

 

Just going trough a problem with the wifes Durango and Denso O2s. Apparently it doesn't like them. My Z71 doesn't like Bosch.

For what it's worth, Standard Motor Products makes many OEM sensors and they make all of GM's.

If you buy them, ask if you can return them if the car won't tolerate them. If they say no, get something else.

Personally I only use Standard and will be replacing the Denso's with Standard in a couple of days when they get here from Summit.

 

i put them in my 97z a few months back and have not a single problem whats so ever
