What is the difference between NGK Laser Iridium and standard Iridium IX plugs?
What is the difference between NGK Laser Iridium and standard Iridium IX plugs?
NGK Laser Iridium plugs are custom-engineered for specific vehicle manufacturers as direct Original Equipment (OE) replacements. They feature a laser-welded Iridium center electrode and a Platinum pad on the ground electrode to deliver maximum, 80,000+ mile longevity. By contrast, Iridium IX is a performance aftermarket upgrade designed primarily for older vehicles, featuring a standard nickel ground electrode and a shorter lifespan.
Do I need to gap my new Laser Iridium spark plugs before installing them?
Do I need to gap my new Laser Iridium spark plugs before installing them?
No. NGK Laser Iridium spark plugs are precision pre-gapped at the factory to match the exact specifications of the vehicle they were designed for. Attempting to manually adjust the gap with a traditional coin-style gapping tool can easily snap or fatally damage the ultra-fine, delicate Iridium center electrode.
Should I use anti-seize compound or grease on the spark plug threads?
Should I use anti-seize compound or grease on the spark plug threads?
No. NGK spark plugs feature a special trivalent metal plating applied at the factory, which provides outstanding anti‑corrosion and anti‑seizing properties right out of the box. Applying additional anti‑seize paste acts as a lubricant, which alters torque wrench readings and can easily lead to over‑tightening and snapping the plug inside your cylinder head.
How often should NGK Laser Iridium spark plugs be replaced?
How often should NGK Laser Iridium spark plugs be replaced?
Because they utilise highly durable dual precious metals (Iridium and Platinum), these plugs offer superior wear resistance compared to standard copper or platinum plugs. Under normal driving conditions, Laser Iridium spark plugs are designed to last between 80,000 and 100,000 miles. However, you should always refer to your vehicle owner's manual for the specific replacement interval recommended for your engine.
