Review on 🔌 Champion Copper Plus 439 Spark Plug: High-Performance Pack of 4 by Michael Moonin

Bought these for my 2004 Dodge Ram 1500 4.7 V8 that uses the same plugs. The truck gave me the cylinder misfire code, and it was tuning time anyway. I decided to change the spark plugs along with the ignition coils, so I bought these. They came with a .040" gap (spec for this engine) and I checked with a gap tool. In the picture you can see one of the old spark plugs (original for the engine) on the left and the new one on the right. So far the truck works without it Codes flawless and even seems a bit more responsive, I recommend them.
