new spark plugs for 2007 5.3 silverado
 

6 bucks isn't bad for a quality plug. I wouldn't put in a inferior plug just to save 10 or 15 dollars

I didn't realize 6 bucks a plug was a good price. I'll pay it but I won't like it. I'm 63 years old. the last time I bought a spark plug it was
47 cents champion n series for a 440cu.in. dodge charger

Guess that's for ac delco iridium plugs? 6$ ain't bad at all, but you can substitute those for the ngk tr55 plugs at oriellys for around 2$ a plug. They last about 50k vs 100k for the ac delco plugs

Rock auto will give you choices on the parts you want to purchase. They mail them to you and there is a shipping fee associated, but as suggested try other parts stores if you fell the price is too high.
