MSD Iridium Tip Spark Plugs

MSD Iridium Tip Spark Plugs are built to improve combustion efficiency and deliver strong, consistent ignition for street, strip and trail engines. Each plug has an iridium center tip. Iridium is a very hard material that promotes a strong spark and holds up well to wear. These performance spark plugs suit high-output street engines, hot rods, muscle cars, trucks, SUVs and sport compacts.

Key Features:

• Iridium center tip: Promotes a strong spark and long service life.
• Copper center core: Helps draw heat away from the tip.
• Yttrium-enhanced ground strap: The strap is machine-ground to handle the heat of high-horsepower ignition systems. It also exposes more of the flame for more complete combustion.
• Proprietary ceramic insulator: Improves the dielectric strength of the plug housing. The spark is forced to jump the gap, even under high cylinder pressure, instead of leaking through the housing.
• Wide application range: The line is offered in a variety of thread, reach, seat and heat range configurations. Choose the plug type that matches your engine's requirements.

MSD drew on its motorsports experience to design these plugs. Its work in NASCAR and NHRA gave it insight into high-RPM endurance and spark isolation. Whether you are upgrading an existing ignition setup or maintaining a performance build, MSD iridium spark plugs give you a dependable, high-quality ignition upgrade.
