Try this:
Take a set of Champion Plugs (Truck or regular) and a set of
Autolites...measure the resistance from tip to center electrode and
note the variance between plugs. I had a person contact me with his
findings and the Champion's were all about 15-20% in variance between
each other...the Autolites were about 2-5%. I didn't quite believe it
so I tried it myself...the Autolites were within 2-5% and the Truck
Plugs (picked up from local parts house) were more than 10-15% in
variance (at minimum). This tells me that the plugs are not built under
stringent quality checks like the Autolites. (Yes...I checked a set of
AC Delco's as well...they're also within 2-5%.)
Personally, I ran the Truck Plugs in my '97 V6 (before any serious
modifications) and they ran fine for about the first month. Then,
performance started to lag a bit so I pulled them out and put the
Autolites in...performance came back. I've even tried them in my wife's
'94 Jeep GC (4.0L) and found similar results as well (she runs AC "Rapid
Fires").
While the Champions are by no means worse than the stock plugs...there
is some QC issues with their plugs even in the higher grade line (Truck
Plugs).
That's my 2-cents worth.

Here's a description of Champion's Truck Plug for what it's worth:
Champion Truck PlugT was designed specifically for pickup trucks and
sport
utility vehicles. Features include a black glazed, zirconia-enhanced
ceramic
insulator which offers 40% more strength than other spark plugs. This
provides durability under rough driving conditions. The massive copper
cored
center and ground electrodes are 20% larger than ordinary spark plugs.
This
design allows the plug to thrive in the rough environments of trucks and
sport utility vehicles. Tests have shown substantial increase in
electrode
life over standard designs in truck engines. The plug carries a
three-years/unlimited mileage warranty. When you want a no-compromise
spark
plug for a truck or sport utility vehicle, Champion Truck Plug is the
only
choice.
It may be a big joke. I personally didn't have any problems with them
and
will put them back in my truck for just that reason.
