Description
The Mishimoto MMIG-LSHS-9908 is a direct-fit set of 8 ignition coils engineered specifically for 1999-2007 GM L-series V8 engines that use heatsink-style coils. Built as a Mishimoto ignition coil replacement for the LR4, LM7, LQ4, LQ9, L59, and L33 engine codes, this coil-on-plug (COP) set is designed to restore consistent spark across every cylinder and is backed by the Mishimoto Lifetime Warranty.
A properly running engine depends on fuel, air, compression, and spark, and weak spark from a tired ignition system can cause misfiring, rough idling, poor gas mileage, and even damage to your catalytic converter. This Mishimoto ignition coil set is designed and tested to meet or exceed OEM GM performance specifications, helping improve engine startup, idle, and overall performance. Each coil in this set of Mishimoto ignition parts uses a high-quality phenolic resin outer shell for durability in high-temperature underhood environments, refreshing the ignition system so it delivers strong, reliable spark whether your vehicle is stock or modified. The set replaces GM part numbers 12563293, 19418992, 10457730, D585, and 19005218, making it a straightforward swap for worn factory coils.
