Mallory HyFire IVC CD Ignitions

Mallory's HyFire IVC CD ignitions give you a hot, race-ready spark, and protect your engine against over-rev with two proportional rev limiters. With their capacitive discharge (CD) system, they give you a stable, uniform spark throughout your engine's rpm range, with no high rpm drop-off like other boxes. The programmable rev limiters give you a high rpm limit, and the other is a staging rpm limit. The limiters are adjustable from 1,000 to 12,000 rpm in 100 rpm increments--no chips or modules to buy. Compatible with most electronic and magnetic trigger systems, they also feature a bypass function that allows you to quickly and easily revert back to your standard ignition.
