I remember seeing some questions regarding the worth of the Lexus factory ignition system so I did some questioning of my own with Jacob Electronics. For those who aren't familar with Dr. Jacobs, he's one of the few actual electrical engineers working with aftermarket automobiles. I've used his Nitrous MasterMind & Omni-Pak ignitions more than once & his stuff performs like he says or your money back! I inquired as to an I.C.E. Pak ( Jacobs import ignition systems ) for the GS4 & was E-beamed back within an hour with the statement that it's development had been considered but that there wouldn't be enough performance gain for the customer to get his money's worth!! This is from a cutting edge company who sells only car electronics!!:eek: This tells me two things: 1. Jacob's is like Swift in that they can be trusted to be honest & forthright in their business & 2. That the Lexus ignition system is first rate as it comes from the factory. Put your performance money elsewhere in the GS!!

 

Thanks for your info, Mean Gene.
