Denso iridium racing spark plugs feature a special hardened insulator that is 20% stronger for hard core racing applications. 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. Patented self-cleaning electrode design. Silicone oil coated insulator to repel moisture and carbon buildup. Handles extreme compression and boost levels. Machine rolled threads prevent seizing or cross threading during installation and removal. 100% pre-fired to assure the highest quality possible. Purified alumina powder insulator provides exceptional strength and thermal conductivity. Five rib insulator prevents flashover. Copper-glass seal bonds center electrode and insulator for a gas-tight seal. (Requires purchase of qty. 4)

Disclaimer:
Qualified Manufacturer Declared Replacement Part means any aftermarket part intended to replace an original
equipment emissions related part and which is functionally identical to the original equipment part in all respects which
in any way affect emissions (including durability), or a consolidated part, that has been evaluated and declared by the
manufacturer to meet this definition and carry this categorization and designation label. This manufacturer has declared
in writing that it has documentation, based upon sound engineering judgment, indicating the replacement part does
not reduce the effectiveness of any required emission control device and it does not cause the modified vehicle/engine/
equipment to exceed applicable emissions standards for that make/model/year fitment(s) advertised
