Why buy new when you can restore?
Do the 5.3's burn up plugs or what? AC Delco's don't last?how much were they?? and let me know how they work out for you...i want to upgrade mine too!I was gonna change my spark plugs, but the engine is still frikkin hot as fWONk.

From everything I've been hearing and reading, thats one of the few plugs that actually do good in these 5.3 Chevy engines. They sell for $7.99 a peice at Advance, but I got them for $5.10 each since I had a 20% off coupon.![]()

I've been hearing that regular copper core plugs don't last. The only recommended replacements are iridium or platinum.
