Does anyone know the difference between 163P and 168P Wiseco pistons?
Are the rings interchangeable?
Thanks, Koen
The Wiseco model 163 piston is a cast piston.
The Wiseco model 168 piston is a forged piston.
Both use the same black carbon L ring and square ring.
The 168 forged piston is the better of the two pistons.

Hi Allan, thanks for the information.
I am looking for a pair of piston rings yet. Hence the question of they are interchangeable.
I've bought long ago several sets wiseco rings from you.
It seems that there is a color difference of the piston rings.
Sometimes they are completely black and sometimes they have a silver colored side.
The black are sharp on the side, the silver are slightly rounded.
See the two different piston rings in the picture.
