Ngk CR9EIX Iridium spark plugs Details Wrench size 16,0 mm Thread diameter 10,0 mm Thread Length 19,0 mm Spark gap 0,8 mm Resistance interference free, 5 kOhm Iridium spark plugs from NGK currently represent the highest quality technological solution. IRIDIUM. The fine-wire design produces a consistent and stable spark that refines the electrodynamics of the Plasmacore ignition event. Because of that, iridium spark plugs have the greatest durability and allows you to get the most possible use out of them. Iridium Spark Plugs. Iridium spark plugs are among the most technologically advanced spark plugs available on the market today. It is welded on in a special process using a laser. Iridium composition of the spark plug provides a high melting point and great strength, and provides excellent wear resistance and durability. Download Spec Sheet Where to Buy Part Finder. (IW06 has no resistor.) FREE Shipping. The same plug may be specified for several different engines, requiring a different gap for each. Because iridium is costly, iridium spark plug manufacturers reduce the diameter of the center electrode to as little as .4mm. Iridium Long Life Plug - Patented Iridium Alloy Plug (90% Ir) with Platinum Ground Strap. How Long Will My Iridium Spark Plugs Last? Iridium radioisotopes are used in some radioisotope thermoelectric generators. Since iridium is expensive, iridium spark plug manufacturers reduce the diameter of the central electrode to 0.4 mm. As a result, less voltage is required (not more than 5000v). You must have guessed that iridium is harder than platinum. 1. Iridium IX® plugs are an excellent upgrade from standard nickel plugs.
