Top Anti fouling Platinum Plug

NGK 5899 Laser Platinum Spark Plug - IZFR5J, 4 Pack

Provides high ignitability and longer service life compared to conventional nickel spark plugs.
Provides stable idling, superior anti-fouling, improved fuel efficiency and lower emissions.
High-grade pure alumina ceramic and 98% pure copper core prevents spark plug from overheating.
Actual OE or equivalent replacement spark plug.

Double platinum point pad on center and ground electrode offer excellent durability and consistent voltage demands to help reduce wear on ignition system.
The same performance as your GM vehicle's original factory component.
Spark plug distributor boot shape and materials provide proper fit, installation, and water-tight seal.
Pure copper core results in cooler electrode temperature for maximized durability and fouling resistance.

MAXIMUM PERFORMANCE: Every Platinum spark plug is necked-down center electrode fires quicker and cleaner, with less voltage for easier starts and quicker acceleration..
IMPROVED DURABILITY: Our spark plugs are platinum-to-platinum firing for superior durability and super conductive Yttrium enhanced ground electrode provides superior heat transfer.
CONSTRUCTION: These spark plugs are platinum enhanced high nickel alloy side electrode maintains precision gap and assures virtually no gap erosion for longer plug life.
FUEL EFFICIENCY: The Autolite Platinum automotive replacement spark plug works to optimize engine performance for a longer life and improved fuel economy..
AUTOLITE ADVANTAGE: Autolite has been producing spark plugs since 1936 making it one of the most trusted and reliable brands for your OE replacement spark plugs needs.
