Since over 90% of the mixture is ignited by the leading plugs, there'd be minimal gain for the extra hassle. The trailing plugs are really only there to ignite the left-over mixture not ignited due to the long skinny shape of the combustion chamber, helping fuel economy and emissions.

Honestly, your gains will be minimal. All I discovered is a smoother idle and slightly better throttle response. IMO for the price for the stock ignition system is excellent more than up to task. If your car is highly modified or pushing higher than normal boost levels then I guess I can justify all that money for one.
