[s-cars] //S4cylinder, almost again!

Just be happy that the tip didn't wind up creating a short like it did in my
car one time and toast the ignition coil.

I almost turned my name back to "Angry Jim" today. On the way home, as soon
as I started to slow down and down shift for the toll booth heading west on
the Atlantic City Expressway, I lost a cylinder and it sounded like I had a
lifter collapse. So I babied it to the rest stop and checked it out. It
wasn't a fuel injector and I always keep spare POS's in the glove box. I
swapped them out and it made no joy. So I jumped in the car and drove it
slow. I made it home and immediately pulled the coil pack cover and started
pulling plugs. Of course you find the culprit in the last thing you do. I
started at #5 and made it all the way to #2 with the plugs looking perfect.
#1 was missing the entire center electrode and the body was very loose from
the rest of the plug. I fished around the top of the piston for any magnetic
bits and installed another plug. Now this is the exact same thing that
happened to the previous owner of my S4 when it was the complete Lehmann
engine. Except that time it
 was #4 cylinder. Is there another alternative to the Bosch F5DPOR plug? I
think these plugs work great, but at the price for these things, who needs
to replace them every few thousand miles? These plugs were brand new and I
have about 5000 miles on this engine build. I dodged a bullet this time. The
center electrode disintegrated and after I installed the new plug, a test
drive confirmed that everything was back to normal.
