Rockauto has the AC41-101 for $5.30/eaIts a 2004 vp 4.3gxi-e. Yeah, I'm not crazy about champion plugs. The ones I have now are pretty expensive. Just as much as factory plugs.
BTW...ditch the Clymer manual and get an OEM one.I think I'll just stick with that plug. The rebate will make an even sweeter deal. It's identical to the densa branded plug recommended in my Clymer manual.
