1990 Ford Mustang 5.0L 02 sensors work great! Perfect fit!
Replaced both 02 sensors on my 1990 Mustang 5.0L . Worked great, perfect replacement. The check engine light went away. Engine was running better enough to lower my idle(adjusted screw) down to 600 rpms without the car dieing. Have had them on for over a week now, and still no issues. Shipping was fast too! Received earlier than stated by USPS originally. Looking at the 02 socket on the website though, it will work from driver side 02 sensor but passenger side is a very tight fit and never tried it but used something similar. I had to get a narrower socket to fit. Just a recommendation, some people just use an adjustable wrench.
