NGK Laser Iridium Spark Plug (LZFR5CI-11), Box of 4, for Select Chrysler, Dodge, Jeep, Ram, Fiat 2008-2020

Fits select 2008-2020 Chrysler, Dodge, Fiat, Jeep, and Ram vehicles (including 300, Challenger, Charger, Grand Cherokee, and Ram 1500).

NGK Laser Iridium spark plugs represent the pinnacle of OE-replacement ignition technology. Designed to meet the exact specifications of original equipment manufacturers, the LZFR5CI-11 features a laser-welded iridium-tipped center electrode. This construction provides a more stable spark and superior durability compared to standard platinum plugs, effectively resisting electrical erosion over a longer service life.

These plugs are engineered for modern distributorless ignition systems, featuring a platinum pad on the ground electrode to ensure even wear across both terminals. The high-grade pure alumina silicate ceramic insulator and 98% pure copper core facilitate rapid heat dissipation, preventing pre-ignition and fouling under heavy loads or high-temperature operating conditions.

• Laser-Welded Iridium Tip: Six times harder than platinum for extreme durability and a focused, reliable spark.
• Platinum Ground Electrode: Provides consistent gap retention and uniform wear in waste-spark systems.
• Copper Core: Superior heat removal capabilities to prevent the plug from overheating.
• Trivalent Metal Plating: Delivers superior anti-corrosion and anti-seizing properties for easier removal.
• Triple Seals: Eliminates the risk of combustion gas leakage through the shell.
• High-Grade Ceramic: Pure alumina silicate insulator offers high dielectric strength and thermal conductivity.
