Best Platinum Spark Plugs

Bosch Automotive (8165) OE Fine Wire Double Platinum Spark Plug - Single

Laser welded Platinum inlay ground electrode provides 3X longer service life compared to standard copper plugs.
Fine wire Platinum firing pin for better ignitability and performance.
Unique 360 continuous laser weld fuses corrosion resistant Platinum firing pin to base.
Nickel-plated rolled threads provide superior resistance to corrosion and do not require anti-seize for installation.
Bosch Double Platinum spark plugs are pre-gapped at the factory and do not require a gap adjustment prior to installation.

G-Power Platinum Alloy Spark Plugs offer superior performance with improved fuel efficiency, lower emissions, and quicker starts.
0.6mm laser welded fine Platinum tip reduces required voltage ensuring high durability and a consistently stable spark.
Special configurations are used for the insulator noses to improve throttle response and prevent fouling with corrugated ribs on insulator to prevent flashover.
Platinum alloy ground and center electrode for greater spark while ensuring precise gap during the life of the plug.
Trivalent Metal Plating offers superior anti corrosion and anti seizing properties while the triple gasket seal eliminates combustion gas leakage.

EXTENDED CHANGE INTERVAL: The Autolite Iridium XP automotive replacement spark plug is engineered to last for up to 100,000 miles depending on engine type making it one of the most durable spark plugs on the market today.
FUEL EFFICIENCY: These spark plugs utilize a 0.6mm finewire iridium centerwire tip design with laser welded technology for maximum fuel efficiency. Our finewire electrodes produce more focused and consistent ignitability resulting in less fuel consumption.
OPTIMAL PERFORMANCE: This replacement iridium spark plug provides better durability and a more focused ignition for better overall ignitabilty and optimal performance.
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 plug needs.
CONSTRUCTION: Every iridium spark plug comes with a platinum protected ground wire for maximum efficiency in all ignition types including DIS systems and a V-trimmed ground electrode for improved ignitability.
