【Iridium Spark Plugs】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
【Replacement spark plugs】Whether the spark plug needs to be replaced, take it out to check the color of the burn, the gap between the electrodes, whether the gap between the porcelain body and the metal shell is leaking, etc. If you find that the car is difficult to start in a cool state, there is obvious driving frustration, idling jitter, or engine acceleration performance declines, you should check the spark plugs in time. May be caused by aging spark plugs.
