KR9CI NGK Iridium Spark Plug | Genuine NGK Spark Plug

Product Description

NGK Iridium Spark Plug Part Number: KR9CI

Iridium NGK spark plugs offer a longer service life than a standard nickel-tipped spark plug: while nickel-alloy plugs offer a service life of roughly 20,000-40,000km, NGK Iridium IX spark plugs offer a service life of up to 60,000km, so fewer replacements are needed over time despite the higher initial cost.

Precious-metal spark plugs like the NGK Iridium IX also offer higher ignitability, achieved with an exposed fine-tip centre electrode that promotes superior flame growth compared with a standard spark plug. Iridium has a much higher melting point (2410C) than nickel (1453C), allowing the centre electrode diameter to be reduced from 2.5mm to 0.6mm a smaller electrode mass that reduces the impedance to flame progress, helping acceleration, fuel consumption and idle quality.

Key Features

• Fine iridium-tipped centre electrode for a slow wear rate and stable idle
• Longer service life than standard nickel plugs
• Trivalent metal plating provides superior anti-corrosion and anti-seizing properties
• Corrugated ribs reduce the risk of flashover
• Pure alumina silicate ceramic insulator, providing superior strength and better heat transfer
• Copper core aids in heat removal
• Triple seals prevent leakage
