【Iridium Spark Plug】The precious metal iridium in iridium spark plugs has the characteristics of high melting point, high strength and high hardness, Use of high-quality iridium spark plugs, its central electrode using fine iridium, to achieve a more superior ignition, significantly improved sensitivity, iridium spark plugs can make a stable jump fire, improve engine running stability and smoothness, while due to the hardness of iridium, making more durable than ordinary spark plugs.
【Improved Fuel Efficiency, Lower Emissions and Quicker starts】Iridium offers better engine idle stability and smoother performance,allows for smaller, more efficient electrode designs for improved cold starting and quicker acceleration.
【One Piece Suppressor Seal】One piece suppressor seal blocks radio frequencies that can affect vehicle electronics.Suppressor seal meters spark energy for longer electrode life and seals against combustion leakage
【Replaces Part Number】DCPR8EIX 6546 97181
【Long Service Life】Iridium Spark Plugs are engineered for original equipment and replacement applications. Every component either matches or improves on the OE design to ensure fast and easy installation with superior performance and reliability and provide long service life.
