What Type of Spark Plugs?

[Jack W]

'05 5.7 with 143,*** miles. Never had to change plugs but now I think I'll need a tune-up. What type of plug is recommended for this engine? Copper?

Pull one and replace with same.

More than likely the original are Champion plugs

OP, this is the plug that originally came in your 5.7L Hemi.

Will putting in Platinum plugs screw with the 'puter?

The early engines tend to not like anything but the coppers but it's your truck.

I ran Autolite Platinums in my old 04 with no problems at all
