Yup - happens all the time. The worst culprits were the Autolite plugs -
seen many of them practically falling apart - right outta the box. They can
look good on the outside, but be trash on the inside. (Funny - same company
does Fram oil filters - seen too many of them rattle around inside - right
outta the box too - QC anyone ???)
Let's do some fun math.....
If you think about it - it's a wonder they work at all... let's say you're
running @ 4000RPM - each spark plug would be firing 500 x / min - thats
roughly 8 x/ sec - in a filthy, high-pressure atmosphere. Add that to the
fact that most older cars are tuned overly rich and have somewhat worn rings.
Lets say you do 10,000 freeway miles per year - thats somewhere in the
nieghborhood of 5 million precise "sparks" needed between annual plug change.
Let's see YOU hold up like that ! <G>
