Look in the HELP section of your local parts store.

 

I bought the accel cap/rotor/wires/plugs for 99 bucks. The wires last a long time if you can keep them off your headers/manifolds. I don't like their spark plugs. They are about 1.4 inch shorter than the stock plugs....but they seem to work.

One time, they sent me the wrong size rotor. So don't get the accel "package" deal.

If you want to go "all out" Get Pulstar plugs and magnecor wires. Those two will cost you about $300 for 8 plugs and 8 wires. But I have heard, from very reliable sources, that they are really good. I am getting them when I do my tuneup next spring.

 

I put these http://www.nology.com/hot.htmlwires with their profire coil on my bike. It helped it start and idle better imo but I couldn't notice any top end power increase. I'd try it on the dodge in hopes of maybe enhancing efficiency slightly but it's some spendy stuff by the time you get enough for a V8.

They also have some silver core plugs if some rich guinee pig wants to try them and get back to me on all the hp it gave you.
