NGK Spark Plug & Iridium Spark Plugs – Replacement for Gasoline & Gas Engines
We are a professional wholesale supplier of genuine NGK spark plugs, offering a complete range of NGK iridium spark plugs and NGK Laser Iridium spark plugs for automotive, motorcycle, and small engine applications.
The NGK Laser Iridium spark plug represents the pinnacle of NGK’s OE technology. It features a laser-welded iridium center electrode and a platinum disc on the ground electrode, providing exceptional wear resistance and a long service life — typically up to 100,000 km — while maintaining a stable spark gap. This makes it the ideal choice for modern high-compression and turbocharged engines that demand precise ignition timing and high thermal durability.
For a wide range of standard and performance applications, the NGK Iridium IX spark plug (often referred to as NGK iridium spark plugs) delivers a significant upgrade over conventional nickel plugs. The ultra-fine 0.6 mm iridium center electrode reduces the required voltage, improves throttle response and contributes to lower fuel consumption and emissions. It is a popular choice among workshops looking to offer premium replacement options with visible performance gains.
Both series use high-purity alumina ceramic insulators for excellent dielectric strength and thermal conductivity, and are built with precision-rolled threads and anti-seize coatings for trouble-free installation. Covering engine families such as Toyota’s 1ZR, 2ZR, 3ZR, 2TR, 1KD, 2KD and many more, our inventory ensures a perfect NGK spark plug replacement for virtually any mainstream vehicle.
