Compared the 2 side by side - Dont look the same... plug connector is... I replaced the front one about 1 yr ago - looked the same. p/n's match. Car is a 98 SVT. Has anyone recently replaced the upper O2 sensor with a BOSCH pn 13115, and found it dramtically differnet than the orig? TIA, Lee 98 Black SVT

The Bosch 13115 has the correct plug end, threads etc... just looks a LOT different... I am going to try it & will post later.. Lee 98 Black SVT
