MERCURY 92-858064K01 Marine SAE 90 High Performance Gear Lube, 1 Quart

NGK NGK iridium plugs represent the ultimate evolution of spark plug technology and performance. The iridium center electrode is both stronger and harder than platinum. This tapered cut iridium center electrode reduces the voltage requirement for spark. This allows for a brighter, stronger spark from your existing ignition system. A platinum tipped ground electrode further contributes toward the extreme longevity of this plug.

Tapered-cut ground electrode improves ignitability and reduces quenching
98% pure copper core increases heat dissipation for more reliable starts and prevents spark plug from overheating
High-grade alumina silicate ceramic insulator for superior strength and heat transfer
Iridium is six times more durable than platinum
