Will these coil packs improve my fuel economy?

While Granatelli coil packs are designed to improve combustion, leading to better engine efficiency, actual fuel economy improvements can vary based on driving conditions and other modifications to your vehicle. Expect slightly better MPG, but don't count on huge gains.

Are these coil packs direct replacements for my factory coils?

Yes, the Granatelli Malevolent Coil Packs are designed as direct replacements for your factory coils on GM LT engines. Remove the old ones, plug these in, and you're good to go.

Do I need any special tools to install these?

No special tools are required for installation. You'll need basic hand tools to access and remove the factory coils, but the Granatelli coil packs install using the same mounting points and connectors.
