• 100% platinum 0.8mm ground electrode reduces wear under severe driving or race conditions.
• Ultra-fine 0.4mm diameter iridium alloy center electrode reduces voltage requirements, greatly improving ignition performance.
• Special hardened insulator is 20% stronger for hardcore racing applications.
• Patented self-cleaning electrode design ensures consistent performance.

Why buy this product? The Denso IRE01-35 HP Iridium Spark Plug is engineered for extreme conditions, featuring a silicone oil-coated insulator to repel moisture and carbon buildup. It handles extreme compression and boost levels, making it ideal for racing. Machine-rolled threads prevent seizing or cross-threading during installation and removal. Each spark plug is 100% pre-fired to assure the highest quality possible. Additionally, the purified alumina powder insulator provides exceptional strength and thermal conductivity, while the five rib insulator prevents flashover. The copper-glass seal bonds the center electrode and insulator for a gas-tight seal, ensuring maximum efficiency and longevity. For automotive use only, do not use in aircraft.
