Are these Ignition Modules worth the money. I think MSD has one for around 200 bucks for my 96 dakota 5.2L. What do that actually do?

 

A module no it is not worth it on a stock EFI. Just get a high performance coil, high per. wires, autolite 3923 plugs. High per. cap and rotor. And your ignition system us as good as it is going to get.

 

What about My 89 3.9l. Is there even any kind of performance products out there for it. Also can someone explain how to change the cap and rotor ive never dealt with any of that kinda stuff.

 

Nevermind. Dang that's too easy. I feel like a retard... LOL

 

crazy is right unless your running at least mild intake and a cam and bigger injectors its just a waste of money you'll get gains but there not enough to be worth the money you would have to spend on it. if you do decide to upgrade that stuff the 6a box is great i had one for the iroc-z i used to have you can feel the difference. i should have never sold that car lol
