NGK 4772 Iridium IX Spark Plug - DR9EIX, 4 Pack - 4772
The improved throttle response, superior anti-fouling and high-ignitability makes Iridium IX ideal for the performance enthusiast. Iridiums extremely high melting point is perfectly suited to todays high-temperature engines, delivering outstanding acceleration, fuel efficiency and durability. Fine iridium tip ensures high durability and a consistently stable spark. Trivalent metal plating for superior anti-corrosion and anti-seizing properties.
Tapered-cut ground electrode improves ignitability and reduces quenching
98% pure copper core and high-grade alumina silicate ceramic insulator increases heat dissipation for reliable starts and prevents spark plug from overheating
Cold-rolled threads to prevent cross-threading and damage to cylinder heads
Trivalent plating eliminates need for anti-seize
Quantity: 4 per package
