Description

NGK 7789 KR7AI Laser Iridium Spark Plug – Ultra-Premium Performance

Restore original engine power, secure immediate cold starts, and maximize fuel efficiency with the NGK KR7AI (Stock #7789) Laser Iridium Spark Plug. As an ultra-premium replacement plug, the KR7AI is highly sought after in Sri Lanka for imported Japanese Domestic Market (JDM) compact cars, microvans, and lightweight trucks.

The Laser Iridium Advantage

Designed for modern, high-revving small engines, this plug features an Iridium-tipped center electrode. Iridium is one of the hardest metals on earth, possessing an extremely high melting point that provides unmatched durability and wear resistance over a long service life.

The ultra-fine center electrode design reduces the ignition voltage requirement, creating a incredibly stable, concentrated spark. This leads to cleaner combustion, smoother idling, and optimized fuel economy—critical benefits under demanding, stop-and-go Sri Lankan city driving conditions.
