Description
The Mishimoto MMIG-LS1-9708 is a direct-fit ignition coil built specifically for GM LS1 and LS6 engines, engineered as a coil-on-plug (COP) replacement that restores the strong, consistent spark these V8s depend on. Offered as a set of 8 (with single units also available), this Mishimoto ignition coil is designed and tested to meet or exceed OEM GM performance specifications, making it a straightforward upgrade path for anyone whose ignition system is showing its age.
A weak ignition coil can lead to misfiring, rough idling, poor gas mileage, and even damage to the catalytic converter, so keeping fuel, air, compression, and spark performing as intended is the foundation of a healthy LS engine before any power upgrades are considered. This Mishimoto ignition coil set refreshes the distributorless ignition system, improving engine startup and idle while restoring the reliable spark that stock and modified vehicles alike depend on. The coil’s phenolic resin outer shell is built to hold up in the high-temperature environment of the engine bay, and each set is backed by the Mishimoto Lifetime Warranty for long-term peace of mind. It’s a practical, no-guesswork way to address one of the most common causes of LS engine driveability complaints.
