NGK 97932 IZFR5L11 Laser Iridium Spark Plug, 14mm, 0.044 in Gap

The NGK 97932 Laser Iridium spark plug (IZFR5L11) is an OE-quality iridium spark plug built for modern, high-efficiency engines. It has a fine-wire iridium alloy center electrode and a platinum-tipped ground electrode. Together they give strong ignitability, a stable idle and a long service life. NGK is a leading original equipment spark plug supplier. This plug is a direct replacement for the original iridium plug in applications that call for it.

Key Features:

• Iridium alloy center electrode: Iridium is about six times denser than platinum and has a very high melting point. The fine wire tip delivers consistent spark energy and wears slowly.
• Platinum tip ground electrode: Unless the original design specifies otherwise, platinum protection on the ground electrode gives good ignitability and even wear, including in distributorless ignition systems.
• Solid copper core: The 98% pure copper core dissipates heat well and conducts efficiently across a wide heat range.
• High-grade alumina ceramic insulator: It helps resist dielectric punch-through and keeps the plug from overheating.
• Trivalent metal plating: The plating resists corrosion and seizing, so the plug installs and removes more easily.
• Resistor design: About 5K ohm of resistance helps suppress radio frequency interference.
