They are generic Champions, and the gapping has been inconsistent on
everybody that I've heard checked them after removal.
The Champion Truck Plugs are good, and standard Autolites are "decent" also,
but I've never like the performance and durability of the standard
Champions.
I'm not running the +4's... they wern't available Dec '97 when I replaced
'em... I'd be curious... the design seems to have potential, but so did the
Splitfire... but I have yet to see definitive proof that the Splitfires are
worth the money.
If nothing else, the design of the +4's elminiates the need to attempt
'indexing' the plugs so the side electrode does not interfere with flame
propogation.
