Description

NGK 93018 LMAR7CI-8 Laser Iridium Spark Plug – Ultra-Premium Performance

Restore factory fuel economy, eliminate low-RPM hesitation, and ensure dependable ignition with the NGK LMAR7CI-8 (Stock #93018) Laser Iridium Spark Plug. Highly demanded across Sri Lanka, this ultra-premium, long-reach plug is the original factory-fitted specification for the country’s most popular modern Japanese import (JDM) hatchbacks, microvans, and lightweight commercial trucks.

The Laser Iridium advantage

The LMAR7CI-8 represents the pinnacle of spark plug technology, combining a laser-welded iridium-tipped center electrode with a platinum chip on the ground electrode. Iridium is one of the hardest precious metals in existence, boasting an extremely high melting point. This provides unmatched resistance to spark wear, extending the plug’s service life up to 100,000 km while maintaining a stable, hot spark.

Designed with a high-efficiency bi-hex/narrow-threaded long reach, this plug positions the spark at the absolute optimal location in the combustion chamber. This reduces ignition system voltage requirements, eliminates cold-start hesitation, and optimizes fuel consumption—which is vital for modern, highly efficient three-cylinder engines.
