The Atomic
EFI outshines the competition in
ease of installation and
performance! The MSD annular ring
injection design produces an
air/fuel charge with much better
mixture as well as an even
distribution among the cylinders
that our competition cannot match.
Better AFRs equal better idle
quality, better starting, and better
overall drivability throughout the
rpm range. You and your engine will
be glad when you Go Atomic.
