Question

NEED TO ORDER ONE JUST. NEED UPPER STREAM THE ONE I KEEP FINDING ARE DOWN STREAM. BEST PLACE TO LOOK FOR ONE

Answer 1

This should be available most auto part stores, the front even though it is a air fuel ratio they still call it oxygen sensor , the between the two not only is it in price , the upstream or A/F is your wide band means the reading is fast , the down stream you don't need that fast of a response, that why they use oxygen sensor which is narrow bad means slow.
