Analyst Opinion (Expert Opinion)

• The spark plugs market is undergoing a critical transformation driven by technological evolution and shifting consumer expectations. Traditional copper plugs, despite being cost-effective, are rapidly losing ground to iridium and platinum variants, which now dominate over 70% of premium replacement segments worldwide. This shift is not just preference but necessity—consider Toyota’s adoption of iridium spark plugs across its hybrid lineup, which underscores the material’s unmatched durability and consistent performance under demanding conditions.
• Moreover, the advent of hybrid and mild-hybrid vehicles challenges spark plug manufacturers to rethink traditional designs. Plug failure rates in hybrids tend to spike due to intermittent engine use, yet most existing products lack this nuanced engineering. Companies like NGK are beginning to pioneer hybrid-specific plugs, but the innovation pipeline remains shallow relative to the pace of electrification.
