The diameter of the ignition end of the center electrode is close to 0.6MM, the ignition is stronger, the combustion is cleaner, the fuel saving is obvious, and it has a strong anti-interference effect, and the service life is 3-5 times that of a general spark plug. NGK G-Power Platinum Spark Plug Set 8PCS. 7090 BKR5EGP. 8 x SKP7090 / 7090, BKR5EGP, BKR 5 EGP - NGK G-Power Platinum Spark Plug. Spark Plug - Set... Misfire could be caused by improper fuel/air mixture in the cylinder. Overheated The insulator nose appears bleached white electrode melted Cause:Pre-ignition,insufficient cooling,low octane gasoline and thin fuel mixture are used. 【Super Durability】:Trivalent Metal Plating offers superior anti corrosion and anti seizing properties while the high performance gasket seal eliminates combustion gas leakage Action:Avoid using lead gasoline,or change touse a hotter type of spark plug Snapklik.co : 68395074AA Transfer Case Control odule Copatible While the engine accelerates,it operates in a high speed,heavy load condition,the temperature of spark plug increase further,then conductivity of the lead compound formed on the insulator surface increases,therefore causing the misfiring of spark plug. An engine with adequate compression and proper fuel/air mixture may fail to properly ignite the fuel charge in one or more serveral ways,depending on the condiction of the spark plugs. Stability: laser welded fine copper tip reduces required voltage ensuring high durability and a consistently stable spark However,the problem is more comonly caused by faulty ignition. Buy NGK 7090 BKR5EGP G-Power Spark Plug, Pack of 4 Online at desertcart It shows the spark plug is suitable for engine. 【Increased conductivity】: Increased conductivity and heat control for good overall. It ensures outstanding dielectric mechanical strength of insulator. Cause:Overheating Action:Regarding to type of spark plug,change to install a colder type of spark plug or higher heat range of spark plug. Analysis of the Cause for Abmormal Combustion The proper servcing of spark plugs can help make the differnce in good engine performance and fuel economy. 【Note】:Please use amazonconfirmedfit to check compatibility before Purchasing. Feature Iridium Tip-Better than OE 360° continuous laser welded center electrode create reliable resistance to thermal shock occurred in new generation engines. 0.6mm Ultra fine wire iridium center electrode provide better ignitability 【Reduce the risk】:Updated design reduce the risk of breaking off during working Lead Pollution The color of the insulator appears powder white,yellow,yellowish,brown,green and black Cause:When an engine operate in low load speed,the 4 ethyl lead in gasoine deposit on the nose of insulator.
