Show original supplier description
The Denso IKH01-24 Iridium Racing Spark Plug is engineered for demanding performance applications, offering enhanced ignition and longevity over factory plugs. Its construction features a ultra-fine 0.4mm diameter iridium alloy center electrode, which reduces voltage requirements for superior ignition performance. This is complemented by a 0.8mm fine wire pure platinum ground electrode designed to reduce wear during severe driving or racing conditions. Built for extreme environments, this spark plug boasts a special hardened insulator that is 20% stronger, making it suitable for hard-core racing applications. It also features a patented self-cleaning electrode design and a silicone oil-coated insulator to actively repel moisture and carbon buildup. The design can handle extreme compression and boost levels, making it ideal for modified engines. Installation is aided by machine-rolled threads that prevent seizing or cross-threading. Each plug is 100% pre-fired to ensure the highest quality. The purified alumina powder insulator provides exceptional strength and thermal conductivity, while a five-rib insulator prevents flashover. A copper-glass seal ensures a gas-tight connection between the center electrode and the insulator. The plug is pre-gapped to 0.7mm and includes a resistor value of 5k Ohm. This Denso spark plug is specifically recommended for 2018+ Audi RS3 8V and 2018+ Audi TTRS 8V models, offering a direct replacement for OEM part number 06K 905 601 M.
