Will these coil packs improve my fuel economy?

Potentially, yes. More efficient combustion can result in a slight improvement in fuel economy, especially if your old coils were weak or failing. However, don't expect a huge change.

Do I need to change the spark plug gap when installing these?

Refer to the manufacturer's instructions for recommended spark plug gap. In general, it's a good idea to check and adjust the gap whenever you replace your coils or plugs.

Are these coil packs CARB-certified?

These coil packs are not CARB-certified. Check your local regulations regarding emissions-related modifications.
