Product Description

The NGK Iridium IX spark plug, part number 3520, is a high-performance ignition component designed to provide superior ignitability and engine efficiency. This plug features an ultra-fine 0.6mm iridium center electrode that ensures high durability and a consistently stable spark, even in demanding operating conditions. The iridium alloy used possesses an extremely high melting point, making it well-suited for high-efficiency, modern engines. The plug is designed with a tapered-cut ground electrode, which reduces quenching and promotes a more complete combustion burn. This design helps improve throttle response, cold-start performance, and overall fuel efficiency. The spark plug is constructed with a solid copper core for enhanced heat dissipation and includes trivalent metal plating on the shell, providing excellent anti-corrosion and anti-seizing properties that facilitate easier installation and removal. This plug is engineered for performance-oriented applications or as a durable upgrade from standard nickel alloy spark plugs. Please verify fitment for your specific application before purchasing.

Key Features

• Ultra-fine 0.6mm iridium tip for stable ignition
