Put some lightning in your engine bay with FM's LS3 coil upgrade.

Note: for cars with a Hydra or other standalone ECU that can control sequential ignition using four individual coils. Currently, the FM221 does not support this feature. While all generations of the Hydra can run the Big Spark, we only have good base maps for 2.7.

High combustion pressures created by forced induction or high compression pistons can overwhelm the spark created by the stock ignition. Inexpensive coil-on-plug conversions don't supply the extra energy required to cope with this.

The coils used on GM LS3 engines - such as the ones found in the Corvette - produce a very high-energy spark. Team these coils up with the included race plugs and never worry about spark misfires again. Since each coil fires a single cylinder, this also means the coils have more time to recharge at high RPM.

We have customers running this setup up to 35 psi boost with a good plug gap, water injection, & no misfires.

This version does not include coils. You can source coils yourself from a junkyard or a GM dealer. You will need Corvette LS2 or LS3 coils, the bracket cannot accomodate some of the larger versions. Includes coil brackets, GM connectors, custom plug wires with a lifetime warranty, a new ground strap, a set of four race plugs and various electrical parts for the wiring as well as instructions for wiring. The VVT version includes new stainless lines for the VVT oil feed. Not compatible with the EGR plumbing.

The kits vary depending on the year of your head. If you have swapped for a different engine, make sure you buy the kit for the engine you are using.
