What are the best plugs and wires for a 98' 4.0?

 

Champion copper plugs and Belden wires

 

stock Champion Copper plugs and 8.5 magnacor wires

 

I had a performance gain when I put the champions in gapped to .040 and msd wires.

 

Champion copper plugs gapped to 035

Plenty of good quality wire options to choose from........just stay away from cheap wires!

 

What parts store carry the champions....and wires range from $15-$31-82....kind of a gap from the $31-$82...Bosch was 31 msd was 82...are the Bosch wires worth it?

 

I found that the dealers wires were cheaper than the "premium" wire sets at Advance/O'Reilly etc. I picked up a set of Mopar wires for under $50. Exact same as the original ones too.

Figure that the original wires lasted 200K miles. Never had good luck with auto-store wires. At all...

 

I love my NGK wires. Same good quality as Belden but they're actually numbered! Helps the tard in all of us. I see them on sale up here for around $24 I think, US prices I guess should be around that.

Champion or NGK copper plugs at 0.035". I wouldn't bother with changing gap unless you've done some upgrades... In which case you should already know what kind of plugs to run lol

 

Hmm makes me think magnacor wires where over kill now....
