need to find out what the stock spark plugs and wires are and dont know how to find out that information

 

stock plugs are champion RC12YC as far as the wires i'm not sure but they are 7mm wires i think

ps post up sum pics of your truck i would to see it i also have a 4x2

 

 

what would happen if i put 8mm or 8.5mm wires on my truck

 

nothing, it would look high performance though, i have MSD 8.5 super conductors, its fast...looking

 

With larger than 7mm, you will probably not be able to fit them in the stock wire holders. You'd have to get new ones.

Other than that, nothing is wrong with larger wires. Might even help the engine run a bit better depending on your other upgrades.

 

i would go bigger and then down the road put a big coil to macth the wires


nice truck thats for the pic

 

champions are the stock plugs and the wires are mopar. but who makes their wires? your guess is as good as mine!! i replaced my wires with stock mopar wires couple years ago, if i remember correctly they were about $40. all i ever use in my truck is stock champion plugs. hope that helps!!
