Set of 4 NGK 94124 Laser Iridium Spark Plugs ILKAR7L11

Set of 4 NGK 94124 Laser Iridium Spark Plugs ILKAR7L11

Premium Laser Iridium Technology

NGK Laser Iridium series spark plugs represent the pinnacle of ignition system component development. The design uses a combination of two precious metals: a central electrode with an iridium tip and a side electrode with a platinum pad. Laser welding ensures an ultra-strong bond of materials, guaranteeing a stable spark even in extreme engine operating conditions. Iridium has an extremely high melting point, making these plugs highly resistant to electrical erosion and wear.

Combustion Efficiency and Fuel Economy

Thanks to the ultra-thin central electrode, the required voltage to break the spark gap is reduced. This contributes to faster and better ignition of the fuel-air mixture, which directly affects the smooth operation of the engine at idle and responsiveness during acceleration. Improved combustion allows for optimized fuel consumption and minimizes harmful emissions into the atmosphere. The use of a platinum plate on the grounding electrode prevents premature burnout, maintaining a constant gap throughout the service life.

Reliable Protection and Durability

The plugs are equipped with a special metal coating that has anti-corrosion properties and prevents the plug from "sticking" to the cylinder head. The five-rib ceramic insulator effectively prevents current leakage and sparking on the outer surface. Internal glass powder seals ensure absolute tightness, eliminating gas leakage from the combustion chamber. The high thermal conductivity of the copper core contributes to rapid heat dissipation, protecting the plug from overheating and pre-ignition.

Wide Applicability and Compatibility

This set of plugs is specifically designed for modern engines with high compression ratios. NGK 94124 (ILKAR7L11) plugs are the original choice for a number of Japanese cars. They are fully compatible with the engines of the following models:

• Mazda CX-5 (produced 2013-2015)

• Mazda 3 (produced 2012-2016)

• Mazda 6 (produced 2014-2016) The plugs meet the strict requirements of manufacturers for heat range and geometric parameters, ensuring the correct operation of the engine management systems.
