Iridium Spark Plugs
Iridium Spark Plugs are engineered to offer excellent engine idling stability and a smooth performance.
Iridium offers excellent engine idle stability and smooth performance One-piece suppressor seal blocks radio frequencies that can affect vehicle electronics Suppressor seal meters spark energy for long electrode life and seal against combustion leakage
Platinum Spark Plugs
Platinum spark plugs are designed to deliver long-lasting performance and maximize durability.
One-piece, fired-in suppressor seal blends three glass types for a gas-tight seal Helps reduce radio frequency and engine interference, regulate spark plug energy and seal against compression pressures for long life Double platinum point pad on center and ground electrode offers durability and consistent voltage demands to help reduce wear on ignition system Pure copper core results in cooler electrode temperature for durability and superior fouling resistance
RAPIDFIRE Spark Plugs
RAPIDFIRE spark plugs are made with ribless insulators to help optimize plug-to-boot seal.
Solid-state suppressor with two-piece glass and brass seal Helps reduce radio frequency interference, regulate spark energy for long electrode life and protect against high combustion pressures Pure copper core provides great heat transfer and helps maximize plug durability Platinum on center electrode enables superior spark characteristics and helps reduce voltage requirements of the ignition system Ribless insulator provides a great plug to boot seal
Conventional Spark Plugs
Designed with a high-quality copper core, these spark plugs help deliver reliable performance.
Black onyx coating helps prevent corrosion Copper core provides great heat transfer and helps maximize plug durability Ribbed suppressor seal extends resistance and helps prevent spark “flash over” and misfires Nickel-chrome alloy sheathing helps prevent corrosion on center electrode Available for use in marine applications
Iridium allows for small, efficient electrode designs for reliable cold starting and quick acceleration
Iridium fine-wire electrode helps burn away carbon deposits on the tip of the plug as they form
One piece suppressor seal helps block radio frequencies that can affect vehicle electronics
Suppressor seal meters spark energy for long electrode life and helps prevent combustion leakage
