Detailed Description
Spark Plug; Plug Number: IZFR6K-11S;
NGK Laser Iridium spark plugs offer the best combination of performance and longevity. Engineered specifically for OE applications, Laser Iridium spark plugs are tested to the highest standards to ensure quality and durability. Iridium tipped center electrode provides durability six times harder than platinum. NGKs high grade pure alumina ceramic and 98 percent pure copper core prevents the spark plug from overheating while providing reliable starts. Most Laser Iridium spark plugs feature a platinum pad on the ground electrode for even wear in distributor less ignition systems
- ACTUAL OE or EQUIVALENT DESIGN: OEM quality construction fine wire iridium alloy center electrode provides consistent performance
- IRIDIUM ALLOY CENTER ELECTRODE: Iridium's density (6x that of platinum) and extremely high melting point is perfect for modern high efficiency engines
- PLATINUM TIP GROUND ELECTRODE: Unless OE specified, platinum protection at the ground electrode provides excellent ignitability and service life
- SOLID COPPER CORE: 98 percent pure copper core offers superior heat dissipation, conductivity and ultra wide heat ranges
- TRIVALENT METAL PLATING: Delivers superior anti-corrosion and anti-seizing properties, ensuring ease of installation and removal
- RECOMMENDED USAGE: Best for vehicles with OE fine wire iridium alloy plugs
This state of the art laser welding procedure brings plug manufacturing to the highest level. NGK Spark Plugs, the leader in advanced spark plug technology, has now struck another milestone in the construction of iridium plugs. In the quest for extended wear, lower resistance with increased efficiency, NGK now produces iridium spark plugs featuring our laser-welded technology. Once again, NGK is leading the way, bonding iridium tips with computer guided laser welders.
- Lasers are used for pin point precision welds, reducing excess debris. The reduction of debris decreases the required voltage to bridge the spark gap.
- Iridium disk welded on the center electrode and platinum disk welded on ground electrode reduces the wear rate on both of these surfaces.
- Ensures great durability and long life.
- Iridium tip is six (6) times harder than platinum.
