Anyone here have the part number for a blacktop SR20DET’s o2 sensor?

I searched online and it says that it’s a 95 300zx TT O2 sensor. However, the 95 Z32 has 3 O2 sensors.

Any help is appreciated. Thanks

John

I belive its an 86 300zx Turbo O2 sensor. I know it is for a redtop, is the blacktop a skinny O2 as well or is it a big ass fuka? I can’t remember now.

No redtop is the skinny one from 87 300zx turbo

Blacktop is the fatty, its different.

It’s got 3 wires… and it looks rather thick
