Im at a 100,000 clicks on the 06 DTS. Car runs great but thought i better change plugs. I went to napa for the ac delco 41-987....they told me the number
has been "super ceded" by the ac delco 41-810...does this sound right? Dont want to go through all the work and find out i dont have the right plug in there.
Thanks guys.

Completely different plug.

Not that I'm a fan of AutoZone, but look at the specs:

Thanks guys,,, I took them back to napa and got the 41-987s at another parts store...they told me at napa the 41-987s weren't available any more. Seems they dont always know what they're talking about. Thanks again for the help.

So much for "Napa know how".

I had a chance to change out the plugs...100,000 miles on the old ones and they didn't look that bad. The job was not as hard as i thought it would be. About 3 hours total...but i work pretty slow. Glad its done...hope the new plugs hold up for another 100,000. Thanks again for the info.
