I am replacing my spark plug wires on my 2003 GMC Sierra. It has the 4.8 V8. I saw these wires on Ebay for a good price http://cgi.ebay.com/ebaymotors/ws/eB...m=200138029418
and was wondering if they would work for my truck.

Thanks

 

They look the same. Best thing to do would be to look up the AC Delco part # for plug wires for your truck and see if they match those. Or just call a parts store that sells AC Delco parts and tell them what you are looking at and see if they match the part number for your truck.
