2001+ Ignition Coil Rail Upgrade...

Does anyone know of any upgrades for the ignition coil rail on the 2001+ TJ's?

or if any company out there has something in the works for Higher Engergy?

Strange I was only thinking about this a couple of days ago---I know nothing but perhaps replacing the rail with individual coil packs--maybe splitfire ?? and using the factory trigger set up--I realy dunno-- I'm guessin a good auto sparks would be the shot ---???
How much do the OE coil rails cost in the US as a point of interest ??

I too am wanting to know if there are any upgrades/mods for the coil packs.. Perhaps individual coils like on the durango/dakota's 4.7l v8? I have a 01 durango as well with that engine and thats what it runs. they are 30$ each at auto zone though.

Not sure how you would get the computer to work with this setup though..

Any thoughts on any other ideas?

Do all other wranglers with a 4.0l newer than the 2001 have the same 3 pack rail system??


Thanks for any comments...

You probably are not asking for the 2.4L but if you are you can get MSD 8229 or MSD 8239. My 2003 Wrangler SE takes the 8239 (flat connector terminals)

The rail (which is one ignition coil per every two spark plugs, so three ignition coils total) is already putting out a much hotter spark than is required to reliably ignite the fuel. Older model cars could benefit by hotter sparks and aftermarket ignitions but the current batch of TJs have, really, some pretty good ignition systems right from the factory. It has to so it can reliably pass the smog tests for no less than five years as mandated by the Feds. If I were you, I wouldn't waste my money looking for a better ignition, you'll get better returns from your money if put elsewhere.
