2 piece spark plugs???
I was just watching a show, Truck U and they mentioned that Ford Truck motors use 2 piece spark plugs! I had never heard this but from what they were saying, over time due to heat and cooling they will contract and expaned. This will allow carbon build up and make it increadably difficult to get the plugs out over time. Basically they were saying that they will break and then you will need to take it to a shop to get it out or carbon will drop into the cylinder. They suggested that the sooner you get the stock plugs out of the motor the better.
So my question is, is this true? And if so, what plugs are you all using?
Thanks in advance
