Hi,
I don't think the amount of 'smoke' is any "indictator" of whether it's doing a better job of B12 or not. I think it's just a property of the chemicals in the fluid.
BTW, I clicked on your link and was impressed with your engine setup ...esp. the K+N filter system.
Can you remember what "part number" or "product code" that K+N setup is?. Does it have a 'hole' for the air temperature sensor?
Thanx,
Gerry
