Differnce between Blktop O2 and Redtop O2? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I had a Blktop SR and was sent a "Red/Black" top SR when I ordered my new motor.

The reason I'm unsure is because the engine had a redvalve cover on it, it also has the skinny type O2 sensor, however, it has the vents on the head like the Blktop heads.

I was wondering if there is a difference between swapping the O2 sensor from my blktop which is a fat type instead of using the Redtop skinny O2?

Connectors are the same didn't know if they read different, both are 3 wires.
