Best way to fire 16 passive coils?

Coil primary resistance is 0.42 ohms. When connecting them in parralel, the resistance goes even less.

V3040P max current is 21A and continuous current is 17A.

Here's the datasheet for the coils: http://www.bosch-motorsport.de/media/catalog_resources/Twin_Single_Fire_Coil_2x1_Datasheet_51_en_2778159755pdf.pdf

Any ideas how I should/can fire these?

You can make a box of transistors and use the TC chips I reccomended.

And no issues from such a small primary resistance?

I feel like lucky bastard driving these doubled on stock igbt's :D

I meant to use 12 IGBTS, two IGBTS being run by a single ignition channel through a TC chip

You mean 16 IGBT's I think :) Yes, that's what I meant.

Too bad these coils cannot be wired in series due to having common +12v supply, not separate..
