Will these coil packs improve my gas mileage?

While these Granatelli coil packs are designed to improve spark and engine performance, any gains in gas mileage would likely be minimal. The main benefit is a more consistent and reliable spark, especially in modified engines.

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

Refer to the manufacturer's instructions for the recommended spark plug gap. In general, it's a good idea to check and adjust the spark plug gap whenever you install new coil packs to ensure optimal performance.

Are these coil packs compatible with aftermarket ECUs?

These coil packs are designed to work with the factory ECU. If you're running an aftermarket ECU, confirm compatibility with the ECU manufacturer before installation.
