Quick 02 Sensor question

Ill keep it simple. Are the fat and skinny O2 sensors interchangeable?

no. they are different.

I have posted links before.

62 = skinny O2.
late blacktop E5/j4 whatever = phatty

thanks alot.

what if i had a redtop (skinny) and i wanted a turbo elbow that used a fat…can i just buy a fatty for my redtop? or do i do something else?
