Its a stock 5.3 litre in my dd truck. I've noticed some decrease in fuel mileage over the last year or so, I guess its time for plugs & wires. Already picked up a set of delco wires but I'm not sure what plugs to run. There seems to be too many choices. Any suggestions?

Those are the ones I use ^^^^^^^^^^

 

I also use tr55

 

Stock ones.

 

I run the stock AC Delco. They are just as good.

 

Yup, Delcos or TR55's stock replacement plugs always work best in a stock truck. They've lasted you this long, why not buy another set of those.

 

The stockers are no longer available. I don't remember the model # but I pulled one last week and went looking for them & found out that they are no longer available.

 

That's BS!! No more Delcos?

 

They have to be in some way or form, I dont think the new trucks would run very well on hopes and dreams.
