does anyone here have a jacobs ignition system, ive been looking at getteing the mileage master or street performer systems and i was wondering if anybody has any input on these, they are kinda spendy so i just wanna know if they are worth it and how do they compare with MSD?

 

Jacobs- not worth it (on the 3.0)- I hardly noticed a difference at all. I got mine for real cheap from a friend so I didnt feel as bad. I was warned that it wouldnt make any difference with my engine. That was my experience anyway...

 

A couple years ago I did try a Jacobs system on my 3VZ. Idle was a bit smoother but no noticeable gain in power and no gain in fuel economy. I sent it back.

 

hey thabks for th ereplys but i have a 22rte, im mainly lookin for somthin to increase gas mileage.
