I have no idea, I thought it was going on Nick's Escort . As I said it allows you to do the above, so providing that the rest of your car's ignition system is up to scratch then it is beneficial. The extent of how this is measured is only a couple of bhp and mpg, but it is just a belt and braces job that the ignition is as good as you can get it. The stronger spark is less prone to boost blow-out though, so is highly recommended on a car running big psi .
