NGK Spark Plugs L, P, R, T, U, X, Y, Z per Unit

• Price per UNIT.

• High-grade silicate ceramic creates a stronger insulator to reduce dielectric punch-through.
• Cold-rolled threads prevents cross-threading and damage to cylinder heads.
• 98% pure copper core increased heat dissipation for reliable starts, prevents spark plug overheating.
• Marine-specific resistor prevents RFI interference with electronics.
• Trivalent plating resists corrosion (especially in saltwater environments); no anti-seize required.
