Another spark plug thread

[doylee4693]

Searched 2003 tahoe spark plug with no results, searched spark plug and got a million different results, mostly for other hears.. no stickies on the very popular topic.. so here I am. What spark plugs is everyome using in their 2003 Tahoe (flex fuel if that matters). I know these trucks are sensative to which plugs they use. Thanks for the help, I feel this really should be a sticky.

Technically the iridium plugs came standard, but later on GM spec'd the double platinums (41962). Some of the guys have a part number for the iridiums that can be used if you want more life out of them. Personally the 41962s I put in at 100K miles will last forever for me.
