which is better for my 91 civic si? the jacobs ice pack , or msd 6A ignition??

 

i dont know about jacobs but i had the msd and i think it worked pretty well.

 

A well maintaned OEM system puts out around 40,000 volts as it is. Sooo, your probably better off with just sticking with stock, and spending your money on something that will give you a gain. Honda's ignition system are way above most other manufactors(sp). Unless your going ALL MOTOR or FI with alot psi...

Using an aftermarket ignition systems, without the above mentioned. Just turns it into more eye candy, rather then a real performance gain... hehehe

Anyway, it's your car and $$$$, so it's up to you on on how to spend it...

 

imo, keep with the stock unless your car is heavily modified...then go with the MSD unit.
