O2 sensor
Fit great. Only complaint is the plug wire is a little long. I had to ziptie the excess out of the way of the steering shaft. Thanks 1A Auto!

Customer Q&A
Ask a question to 1A Auto customers who purchased the product
can this be used on either the upstream or downstream?
S W June 21, 2017
I bought this item for Upstream use only, sensor prongs or 02 sensor itself might be to big or to small for the downstream application
