You'll recognise
the 7AL-2 Plus Ignition
Control, as its predecessor
is the most popular ignition
control used in drag racing.
The "Plus" model updates the
original 7AL-2 with improved
internal components plus our
engineers added a 2-Step Rev
Control and a useful
diagnostic LED. Racers will
be happy to see that the
updated components up the
voltage output and spark
energy! Over 50% more spark
energy in fact! Visually,
you'll notice the two
terminal strips that allow
for easier wiring in your
race car. The LED over the
power connections will come
in handy for troubleshooting
as it flashes only when the
coil fires. That way you know
that the coil, the trigger
source and ignitio n are all
y. The mounting pattern is
the same as the 7AL-2 and is
supplied with vibration
mounts and a few rpm modules.
NOTE: MSD 7 Series
Ignitions are not compatible
with distributorless systems.
