And i have to change 2, each on the exhaust headers.

just wondering if other make oxygen sensor make will do the job as well?

hey man.. from what i've heard(from experts).. just grab the cheap one.. they're just as good... universal Walkers(the brand) seems to be good enought.. go with that. so you can save some cent for a good car wash
