【Improved Fuel Efficiency, Lower Emissions and Quicker starts】Iridium spark plug offers better engine idle stability and smoother performance, allows for smaller, more efficient electrode designs for improved cold starting and quicker acceleration.
【Double Iridium Spark Plugs】Most of replacement plugs are only used cooper/iridium only, Jectam's is used the Double-Iridium same like original one. Every component either matches or improves on the OE design to ensure fast and easy installation with superior permance and reliability and provide more service life.
【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.
【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
