Size of 1999 Audi A4 Quatter O2 Sensor?
Hey i'm looking to replace my Upstream o2 sensor (before the catalytic converter) with a universal o2 sensor. When i shop for one there are multiple sized length for the o2 sensor, between 5.9 and 6.3 inches, id like to know what one is the correct size to use.
Thanks.
Thanks.
