i know Picco triton and werks have a number 5 plug. Wasn’t sure if there the same but I thought they might be the same. I’ve had werks triton Picco 5 they look same pretty much but wasn’t sure but thought they might be.

as far as alpha all the alpha plugs I’ve had are a different shape to them then the werks Picco triton 5 plugs so I’m pretty sure there different factory plugs. They might work in Picco but not sure but the body of them does look different.

I know some people use os p3 in picco.
I’ve used the Picco 5 plugs in a couple tritons.
