    Default Plugs and Wires???

    So I have read every post the search function could find relating to the selection of plug wires and plugs and everything I read seems to be about earlier models, say 2005 and earlier. I have a 2006 Silverado, 4x4 Ext Cab LT3 with the 5.3L V8. It just turned 70,000 so I thought it might be time for some new plugs and wires.

    From the posts I read the consensus on plugs seemed to be either AC Delco or NGK. Does the same hold true for my truck? Do type of plugs came stock in my truck, copper, platinum, iridium?

    For wires all summit shows are some Taylor's (cheapest), AC Delco which is obviously the factory option, and then Granatelli's which are by the far the most expensive but say they offer near 0 Ohms resistance. The Taylor's say they offer 500 Ohms resistance which doesnt seem to be much better than stock but they are much cheaper.

    What other options have you guys used? What do you suggest?

    As far as Wires,there are many to choose from,MSD,Taylor,JBA to name a few.IMO going with one of the ones I have Mention they will be a upgrade over Stock the one's,as far as Plug's I have gone with A/C Delco Iridium Plug's and JBA 8mm Wires,This has been a Very Good setup for me.

    This is exactly my point. I did all this research and decided to go with the AC Delco Iridium plugs and the MSD SuperConductor wires but when I search for my model year none of these appear to be available.

    IIRC, your 99 has the 5.3L 323ci engine and I have the 5.3L 325ci engine. Are the plugs and wires on these 2 engines interchangeable?

    What am I missing?
