im due for my tune-up soon. i dont remember what i put in last time. my question is which plugs and wires do you guys reccomend for the best over all perfromance?? im looking around for good stuff, i just want my rig to run its best like everyone here who loves thier rigs.. thanks guys...

 

I use Champion plugs and have never had any issues.

 

I get my stuff from Napa,life time warranty on plug wires.

 

any specific plugs and wires from them. and are the plugs pre-gapped??

 

which model plugs????. i know champion has a huge line up of plugs.

 

plugs will go buy your year,wires just ask for the better life time warranty ones.

 

plugs are 87-90 4.0 liter RC-9YC , 91-99 are RC-12LYC gap is.035 on all.

 

Mike beat me to it.

 

i run champion oem coppers (gapped to .035) w/ msd wires.

 

the autolite plugs/wires

 

I just swapped in some NGK plugs, I think they're the V2's, and am SUPER impressed, I just run cheapo wires for now, I'm gonna swap in some MSD or Accel wires and run an Accel coil pretty soon.
