Ilmor 41-114 GDI Spark Plug
The Ilmor 41-114 GDI Spark Plug is designed for select Ilmor gasoline direct-injection marine engines used in MasterCraft inboard boats. Built to handle the higher cylinder pressures and precise ignition requirements of GDI technology, this plug provides consistent spark delivery for reliable starting, smooth acceleration, efficient combustion, and strong performance under load.
Direct-injected marine engines depend on the correct spark plug specification to maintain proper combustion characteristics. Worn or fouled plugs can contribute to rough idle, hesitation, misfires, difficult starting, or reduced power. Installing the correct Ilmor 41-114 replacement during scheduled maintenance helps keep the ignition system operating as designed.
This spark plug is an excellent choice for routine service on compatible Ilmor-powered MasterCraft wake, surf, and ski boats. Its durable construction is suited to the heat and demanding operating cycles encountered during watersports, cruising, and extended periods of low-speed operation.

Maintain Proper GDI Engine Performance
Spark plugs are especially important in gasoline direct-injection engines, where combustion depends on precise fuel delivery and ignition timing. Replacing worn plugs at the recommended service interval can help prevent misfires, maintain acceleration, and preserve the performance expected from an Ilmor-powered MasterCraft.
Important Fitment Note: MasterCraft used multiple Ilmor engine packages across the same boat models and model years. Boat model alone should not be used to determine compatibility. Verify Ilmor 41-114 against your engine model, serial number, or original spark plug specification before ordering.
