Plugs for '94 Tbird 4.6.
From http://www.motorcraft.com/catalog.do :
AWSF32P Suppressor Spark Plug PLATINUM
AWSF32C Suppressor Copper Plug
I've run both at one time and another. Only wished to replace a set.
They no longer seem to be available. I call around, actually pick
up a pair of the Motorcraft "replacement parts" for AWSF32P (#SP493).
The AWSF32P has 3/4 " of thread. The #SP493 has about twice that.
To look at 'em side by side (I always do before replacing), it appears
the bottom of the plug would thread about 3/4 " deeper into the head,
possibly resulting in collision with a piston.
Does anyone have any idea what Unnatural Acts dear Motorcraft is
committing with replacement parts?
It runs me ragged, trying to make some sense of their craziness.
