Denso VKH20Y 5639 Spark Plug Iridium Tough Replaces 267700-4540

VKH20Y | 1 - Earthed Electrode | Tightening Torque (Nm): 22 | Diamiter (mm) : 14 | Thread Length (mm): 26.5 Built-in, Highly Reliable Resistor: All specification types include an embedded, highly reliable, monolithic resistor to eliminate electromagnetic noise interference from all kinds of electronic devices. Platinum-tipped Ground Electrode: The ground electrode has a platinum tip. This moderates electrode wear and insures high durability. By greatly minimizing electrode wear, DENSO improved mileage and extended the plug’s useful life. Longevity providing peace of mind and safety when using IRIDIUM TOUGH. Highly Corrosion Resistant: The insulator housing is plated with burnished nickel the same as racing plugs, resulting in high corrosion resistance. (VKA and VKB excluded). Fine Diameter Ultra-fine Iridium Center Electrode: Using DENSO’s iridium alloy having a very high melting point, the tip of the center electrode can be shaped very thin and fine, reducing spark voltage requirements and greatly improving ignitability. Trust DENSO as the market leaders in spark plug technology, imagined, designed, and manufactured with incredible precision in Japan. Over 6 Billion DENSO Plugs Produced to date!
