I bought plugs for my 2003 Silverado 5.3L back in the day and neve used them (NGK TR55IX 7164 iridium plugs), will they work in my 2005 sierra 4.8L?

I'm 99% sure they will but I figured I would ask. Reason is because Evo VIII plugs don't work in Evo IX due to head heights so I'm just double checking

Thanks
John

Ac delco plugs are the only plugs you should be putting back into your GM vehicle

i don't see why not. ngk site doesn't even list those plugs when i searched, but the one they list for 5.3 and 4.8 is the same

I just bought some AC delco plugs from autozone, should do the trick since I'm not after performance. I just wanted some on hand since I seafoamed my truck this weekend. I've heard horror stories of the plugs fouling out and other stuff, but didn't have any issues. I'm going after fuel mileage so I will probably replace them since I already bought them

Gotta agree. Can't go wrong with a 100k mile plug.

The NGK are the same plugs in this application.

Hmm well, I could return the AC delco because I have a receipt, but I bought the NGK like 4 years ago for my black truck and never used them

you can always buy another set of AC Delcos and throw the NGK's in that box and return em

at like walmart or something...

Yes, the NGKs will work perfectly fine. I work at an LS performance shop and we use NGK TR55s for the majority of our naturally aspirated builds. I have them in my LQ9 with the heads being decked .030"
