Little tune up mods

Can any on direct me to a good website to order some good ignition mods I could do.Running on stock motor not knowing what I can really do.I just bought a set of plugs(champion).Need to know what wires and rotor and so on.TIA

I hr later and still nothing??

i don't know a good site but everything i've heard says that cherokees hate modified ignition setups.

MSD plug wires, for sure ... they have WAAAY lower resisitance.
Any cap and rotor with brass connections.
Run 0.040 - 0.045" plug gap.
Remove the vent on the cap and plug it with Silicone.
Put a small bead of silicone on the cap base.
This combination is working great on my '98.

I like Beldin (maybe Belden) from NAPA for wires. They have some 7mm lifetime wires for something like $25. Work great so far.

I just a cap and rotor with brass connections like keener mentioned. I leave the plug gap stock, .035 I believe.

Stock plugs for me. I would rather change them every year for $20 than spend $60 on a set that stays in my jeep for longer.
