IK20G DENSO Genuine New Iridium Spark and 50 similar items

DENSO Iridium Spark Plug – IK20G Product Overview The DENSO IK20G is an OEM-grade Iridium Power spark plug designed for high-performance ignition, improved fuel efficiency, and strong combustion stability. It uses a fine iridium tip electrode to produce a stronger, more concentrated spark while requiring lower ignition voltage from the coil. This plug is commonly used in Japanese engines (especially Honda applications) and tuned or performance-oriented petrol engines where reliable ignition and durability are required. Product Specifications Specification Details Part Number IK20G Brand DENSO Product Type Iridium Power Spark Plug Thread Size M14 1.25 Reach 19 mm Hex Size 16 mm Electrode Type Fine Iridium Center Electrode Gasket Type Yes (Gasket Seat) Gap ~1.1 mm (factory preset) Heat Range 20 (standard mid-heat range) Terminal Solid Type Condition New Genuine DENSO Technical Details Iridium Fine Wire Technology The IK20G features a ultra-fine iridium center electrode that concentrates spark energy, improving ignition efficiency and throttle response. Stable High-Voltage Ignition Requires lower voltage to fire, reducing load on ignition coils and improving long-term reliability. Heat Resistance Longevity Iridium material provides excellent resistance to wear and high combustion temperatures, extending service life compared to conventional copper plugs. OEM Precision Design Built to factory specifications for consistent combustion performance and smooth engine operation under varying load conditions. Gasket Seat Design Ensures proper sealing in cylinder head to maintain compression and prevent gas leakage. Function Benefits Primary Function The spark plug ignites the air-fuel mixture inside the combustion chamber to produce engine power. Key Benefits Strong and consistent ignition performance Improved fuel efficiency and combustion quality Faster cold starts and smoother idling Reduced misfires and engine hesitation Long service life due to iridium tip Lower stress on ignition coil system Compatibility Application Notes The DENSO IK20G is widely used in: Make Application Honda Small engines, Life, Fit variants Japanese petrol engines OEM and light performance tuning applications Modified engines Mild performance upgrades requiring stable spark ?
