New IGN1A Coils! These are a great upgrade from stock LS coil's. We use these on 3 of our personal car's with great results. These are the same coil/fitment as Holley, Fueltech, Haltech, DIY, etc.
***Smart Coils must be triggered on with an rpm output. Wiring them with constant ignition on power with the engine nit running WILL damage and weaken them.***
