The Denso 3461 SXU22HCR11S Iridium Long Life Spark Plug is engineered for superior performance and longevity, making it a top choice for vehicle maintenance. This spark plug features a 0.7mm fine wire iridium center electrode that is laser-welded to a platinum-tipped ground electrode, designed to withstand extreme temperatures exceeding 4000 degrees Fahrenheit and ensure consistent, reliable ignition. Constructed with a purified alumina powder insulator, the SXU22HCR11S offers exceptional strength and thermal conductivity, while the five-rib design prevents flashover. The machine-rolled threads are specifically implemented to prevent seizing or cross-threading during installation and removal, simplifying the maintenance process. Each plug is 100% pre-fired to guarantee the highest quality and optimal performance straight out of the box. Denso iridium long-life spark plugs are recognized for their extended service life, typically offering between 80,000 to 100,000 miles of reliable operation. They are often chosen as original equipment for luxury vehicle manufacturers, including GM, Toyota, Honda, and Mitsubishi. This plug utilizes a copper-glass seal that bonds the center electrode and insulator, ensuring a gas-tight seal critical for efficient combustion.
