86-7023 CR6HS Spark Plug, spark plugs are made to last longer and operate well. These spark plugs feature high alumina ceramics for improved heat transfer and electrical insulation. The solid copper core improves heat transmission and sparks transfer, while the longer insulator nose minimizes fouling and misfiring. Key Features: Trivalent metal plating has excellent corrosion and anti-seizing capabilities. Corrugated ribs prevent flashover. Constructed of high-quality materials that are technologically advanced A longer insulator nose avoids fouling and misfiring. They are not prone to carbon buildup or pre-ignition. Alumina silicate ceramic insulator with exceptional strength and heat transmission The copper core assists in heat dissipation Triple seals prevent leaking Specifications: Brand: Autowares SKU: 86-7023 UPC: 087295070239 Weight: 0.15 LBS Manufacturer Part Number (MPN): 7023 Thread Diameter: 10mm Thread Pitch: 1.0mm Seat Type: Gasket Reach: 12.7mm (1/2") Hex Size: 5/8" (16mm) Terminal Type: Threaded Stud Overall Height: ISO Center Electrode Material: Nickel Type: Standard Size: 2.5mm Resistor: Yes Projection: Non-Projected Heat Range: 6
