I'm not sure if anyone is gonna know the answer to this question but here goes. I have a 2005 blazer and ordered ac delco spark plug wires. They gave 9746kk ac delco spark plug wires. When I look them up it says it for a blazer up to 2004. Do you think that would be a problem to use on a 2005 ? I looked at parts geek and they have 4 different sets of ac delco wires for a 2005 blazer all different prices. I'm not sure why other then 2 of the sets have something to do with X in the vin and the price. I don't think because my wires are for a 2004 it's a big deal but I could be wrong ? When I look on Amazon it shows up to 2005 I'm confused. Here's the info from Amazon. 1998-2005. The only reason I'm asking this question is because of all the misfiring and problems I'm having and I was thinking it might be something really stupid !

 

It is a listing issue due to the fact that the vast majority of sales were to fleet services.

 

I'm not sure what you mean. You say nothing changed so will they will be ok ? I just want to know if these wires are ok to be used on an 05 blazer or are not ok to be used on an 05 ?
