Will these coil packs improve my fuel economy?

A hotter spark can lead to more complete combustion, which may result in a slight improvement in fuel economy. However, results can vary depending on your driving style and other modifications.

Are these coil packs compatible with aftermarket ECUs?

These coil packs are designed as a direct replacement for the factory coils, so they should be compatible with most aftermarket ECUs that support the factory coil configuration. However, it's always a good idea to check with the ECU manufacturer to confirm compatibility.

What is the warranty on these coil packs?

Granatelli Motor Sports offers a one-year warranty on these coil packs. Refer to the manufacturer's warranty policy for specific details and limitations.
