With the factory PCM options are a bit limited in what can be done for ignition system improvements.

The 3800 uses a waste spark ignition system where two cylinders each share one coil. Because of this your coil options are a bit limited unless you want to perform surgery on your ignition control module.

You can switch to aftermarket coils to improve the spark of the factory ignition system.

The L67 and L32 engines are equipped with hotter coils than the L36 or L26 engines. These can be used to improve the performance of the factory ignition as well.

L67 and L32 coils can be identified by the blue tab located on the bottom of the coils.
