You need the coil to supply spark to the engine. The little black box is the cdi. It tells the coil when to fire. The stock cdi has the coil and cdi as a 1 piece unit.

22.99 USA dollars
That would be like $30 CAD and then shipping on top in USD.
LOL no difference between a stock cdi and the super charged cdi, give your head a shake! The super charged cdi is a completely different unit with a better suited base timing and curve, when Rob tested the cdi's on the dyno he did not actually test or show the firing degrees nor did he test it on a high rpm engine which really didn't show or prove anything, Fact is that the super charged cdi has it's base timing upto 10 degrees btdc lower than stock depending on which one you use as the older more common cdi's are timed at 25 degrees btdc and the latter one's along with the TZ's are 20 degrees btdc and the super charged is at 15 degrees btdc, the final timing on a stock unit or TZ just climbs there is NO curve to accommodate high rpm as the higher the rpm goes the more retarded the timing should be and the super charged ends up at around 8 degrees btdc at anything above 8k where the stock unit's and TZ's can be well above 30 degrees btdc at or above 8k and this just beat's the crap out of the crank bearings, piston, wrist pin and bearing not to mention the highly increased risk of detonation.
