MOSFET (N&P)

If you use NPN like the TIP12x that introduces new safety hazard, due to igniters being wired hot, as discussed above with You-Tube video.

There is no harm in using a strong FET, it has lower drop than the NPN or smaller FETs. Igniters will burst more reliably, less chance of a dud, when you turn them on hard and fast.
