Description
The Mishimoto MMIG-LS1-97 is a single coil-on-plug (COP) ignition coil engineered as a direct-fit, standard-replacement unit for GM LS1 and LS6 engines. Housed in a high-quality phenolic resin outer shell built to hold up in high-temperature engine bay environments, this coil is designed and tested to meet or exceed OEM GM performance specifications, and it’s backed by the Mishimoto Lifetime Warranty.
A properly running engine depends on fuel, air, compression, and spark working together, and before chasing more power out of an LS engine it pays to confirm every one of those systems is performing as intended. A weak spark from a tired ignition coil can lead to misfiring, rough idling, poor gas mileage, and even damage to the catalytic converter. This Mishimoto ignition coil refreshes the ignition system to help ensure a strong spark on both stock and modified vehicles, improving engine startup, idle quality, and overall restored performance. It’s available as this single unit or as part of a set of 8, giving owners flexibility whether they need to replace one coil or refresh the entire ignition system.
