$$, but a good project to sink your teeth into<ul><li><a href="http://cgi.ebay.de/ZUNDSPULE-AUDI-S4-S6-S2-RS2-TURBO-5ZYL_W0QQitemZ310054531897QQcmdZViewItem?hash=item 310054531897&amp;_trkparms=72%3A445%7C39%3A1%7C65%3A12 &amp;_trksid=p3286.c0.m14">http://cgi.ebay.de/ZUNDSPULE-AUDI-S4-S6-S2-RS2-TU

So not a good project for anyone. The 12v runs on waste spark. So it uses 3 coils to drive 6 cylinders. If you wired these up somehow you wouldn't gain anything because you're still running on waste spark. You'd need an aftermarket management system to run the coil on plug ignition system for it to do anything worth while. Even then it'd be a complete waste of money..

You'd also have to remember that those wouldn't even fit the 12v at all. The individual coils would interfear with the fuel rail, injectors, valve covers, and intake manifold as they connect directly to the plugs.

to geek out on.
