Re: ping KENN re 99f150

lmfao

I CALL BULLSHIT u have the wrong plug nice try pp is for a coil that fires backwards a single platnim will work since only 1 side of the electrode will burn

school out

It's called a wasted spark system..... and PG plugs aren't available from Ford.... school's not out, you just played hookey.

lmfao

u go dork

"PP" Indicates it is a double platinum plug, i.e., platinum on both the center and outer electrode. Ford recommends these for replacement in engines with waste spark ignition. The plugs installed at the factory are single platinum plugs, but there are two different types. One with platinum on the center electrode and one with platinum on the outer electrode. You only really need platinum on one electrode, but it has to be the proper electrode for the polarity of the spark. For waste spark ignitions half the plugs have the spark jump from the center electrode to the outer electrode, and the other half have it jump from the outer electrode to the center. In a factory situation, they can install the proper single platinum plug in the proper location. For after market, it is just easier to sell double platinum plugs. That way you don't have to worry about mixing them up, and you don't have to stock two different plugs for each applications.
