NGK 5899 Laser Iridium Spark Plug IZFR5J - Replaces Quicksilver/Mercury 33-892567Q - Fits 2006 Mercury Outboard, 2007 Nissan Outboard

The NGK 5899 Laser Iridium Spark Plug (technical designation IZFR5J) is an iridium-tipped replacement spark plug built for reliable marine outboard ignition. The center electrode uses an iridium tip that NGK states is six times more durable than platinum, paired with a copper core for improved heat dissipation and conductivity. The ground electrode uses a nickel core with a standard ground configuration, and the insulator is a ceramic material rated at 5,000 ohms of resistance to help suppress ignition noise. NGK's high-grade ceramic insulator and copper core work together to resist overheating and support reliable engine starts, while every Laser Iridium plug is tested to NGK's quality and durability standards as an actual OE or equivalent replacement part.

This spark plug fits 2006 Mercury Outboards and 2007 Nissan Outboards, and it replaces Quicksilver / Mercury part number 33-892567Q. Each package contains one spark plug. Always check your engine's maintenance manual to confirm the correct spark plug for your specific engine, and only use the plug type recommended by your outboard's original equipment manufacturer, since using the wrong plug can reduce performance and fuel economy or cause engine damage.
