Description
The Denso K20TXR Multi-Ground Spark Plug - 5063 is a dependable OE-style replacement spark plug designed for consistent ignition performance, reduced fouling, and long-lasting durability. Featuring two ground electrodes, this plug is built to improve wear resistance and maintain reliable spark delivery over its service life.
Its fully projected insulator helps reduce carbon fouling, while the machine-rolled threads help prevent seizing or cross-threading during installation and removal. Denso’s high-purity alumina insulator provides excellent thermal conductivity and strength, and the copper-glass seal creates a gas-tight bond between the center electrode and insulator. Pre-fired for quality assurance, the K20TXR is a solid replacement choice for a wide range of BMW, Audi, Porsche, Volkswagen, Mini, Saab, Cadillac, Suzuki, Daewoo, and Saturn applications.
