Performance Distributors GM LS/VORTEC SOS Coils - Manual (Page 9)

Forced induction and higher cylinder pressures make it
harder for the spark to jump the gap, so whether you have
a factory-supercharged engine (like our LSA) that’s had
the boost turned up, or added a supercharger to a
naturally-aspirated engine, these coils are good insurance
against performance-robbing misfires.
Our experiences with Performance Distributors’ SOS coil
packs have been great, overall. Our CTS-V made more
power with them than we expected, plus the drivability of
the car is great. Always remember to do your research
when upgrading your ignition system or any component of
your car in general – it will help you out immensely and
you might even learn a few tips and tricks that will help
you understand how the system/component works with
the engine.
