4.7 Spark Plugs....

[Murphy Slaw]

I bought my '05 with 70,000 miles and always wondered if the plugs had been changed. It ran good and started good, idled smooth and stuff. Not very quick, but it's a small V8 and a Quad Cab 4X4 and I came from a Toyota 4 banger so....

Today was a sunny day off, so I decided to dig in, at 125,000 miles.

I'm convinced these are original plugs. They all looked just like this one.

Unreal.....

yeah, those have some mileage on them.

Hope you replaced them with the copper core plug!
