Set of four NGK (7963) Laser Platinum Resistor spark plugs.
Over time, the electrode on spark plugs wears away, causing a larger gap to form and resulting
in a weak spark. Excess carbon can also build up and negatively effect performance. Using
these factory spec plugs can help restore mileage and performance to your engine and smooth
out poor idle.
We also recommend changing spark plugs more often on vehicles with ugraded performance
software or turbochargers.
NGK extreme life plug. By using the highest platinum content in the industry, NGK has created an
extremely long life spark plug. Laser welded platinum tip on center electrode andplatinum tip on
the ground electrode. The center electrode is taper cut which aids in focusing the spark while
reducing the voltage necessary to start the combustion process, this will provide better throttle
response, improve efficiency and allow a smoother idle. Stainless steel washer reduces plug
*Note: If you are replacing any part of your ignition system on a higher milage vehicle, it is also
best to replace other worn out and serviceable components such as your coil packs or plug wires.
Be sure to search under your model vehicle to see other replacement part options.
