What spark plugs to go with in Mild 05' 4.8 V8 silverado? E3, iridium, platinum?
Looking for thoughts on E3, They didnt work well in my old 95 jeep I got some fouling and missing.
HP TV showed E3 dyno prove they work and lower emissions. But it is TV cant believe it all.
NGK tr55IX, I know they are pricey but I want good plugs for MPG & HP.
Truck is just bolt ons for now

I got over 120k out of my stock iridiums plugs, new iridium plugs cost 80 bucks that's peace of mind knowing I can get 120k again. So you do the math.. I'm running tr6 now because of the H/C. You cant beat the stock plugs for the dependablity..

The stock ac delco or stock ngk will do just fine or go to an ngk tr55. Never been a fan of the Bosch plugs, seen them start misfiring with in 10k-20k miles in some vehicles. I cannot ever bring myself to spend 80 on iridium plugs, way over priced.
