Built for Boosted McLaren V8s Pushing Beyond 1,000 HP
The factory McLaren ignition system was engineered around a stock 562 HP. Push past 1,000 HP and the OEM coils start dropping spark — misfires, lean events, and a long list of frustrations that get expensive fast. Cannonball Garage’s CSO Ignition System Upgrade was built to solve that, holding clean ignition output well past 1,300 HP.
Direct Bolt-In Replacement
Drops straight onto the factory connectors with custom-molded coil boots that guarantee a precise seal. No splicing. No adapters. No reflashing. Pull the OEM coils, drop the kit in, and go.
Engineered for Tuned M-Engines
Designed specifically around the M838T and M840T V8 twin turbo platforms. If you’re running a tune, methanol injection, larger turbos, or a built short block — this is the ignition layer those mods need.
