NGK Spark Plug - DCPR7E Part No.: 37-DCPR7E Key Features: Copper Core: NGK uses copper wire in place of the iron cores found in many conventional plugs, helping to dissipate heat more efficiently and cool both the electrode and insulator tip. High-Performance Compatibility: With a raised pre-ignition rating, this spark plug offers better heat conduction and extended engine life, designed specifically for high-performance engines. For Twin Cam Models: For 1999 and newer Harley-Davidson Twin Cam models, this spark plug is one heat range hotter than the standard DCPR7E plug. Specifications: Heat Range: 7 (optimized for moderate temperature operating conditions). Thread Size: 12mm (ideal for many motorcycle and small engine applications). Gap: 0.028" (0.7mm), ensuring the right spark for better engine combustion. Hex Size: 5/8" (16mm), which fits most spark plug wrenches. Type: Resistor, reducing electrical noise and interference in ignition systems. Weight: 0.06 lbs (lightweight for ease of installation). Applications: This spark plug is ideal for a variety of Harley-Davidson motorcycles, particularly for the Dyna, Electra Glide, and Fat Bob models, as well as BMW, Buell, and other high-performance engines. Some of the key applications include: Harley-Davidson: Dyna Convertible, Fat Bob, Low Rider, Street Bob, Super Glide, Wide Glide, and more (1999–2017). BMW: K1200GT, K1200LT, K1200RS, K1200LT Elite, and Custom (1999–2009). Buell: S1 Lightning, S2 Thunderbolt, and X1 Lightning (1996–2005). Benefits: Efficient Heat Removal: The copper core design helps remove heat effectively, preventing overheating and extending plug life, making it an excellent choice for engines that operate under heavy load. Enhanced Performance: Designed to meet the demanding requirements of high-performance engines, providing a more reliable spark and better overall engine efficiency. Durability: NGK plugs are built with premium materials, such as alumina silicate ceramic insulators, ensuring superior strength and better heat transfer, while the copper core offers enhanced longevity. Construction: Copper Core: Efficiently dissipates heat for consistent performance. Triple Seals: Prevents leakage and ensures durability in high-performance environments. Corrugated Ribs: Prevent flashover, maintaining stable spark even in challenging conditions. The NGK DCPR7E Spark Plug is a great option for motorcycles requiring a reliable and durable spark plug, especially those in high-performance or demanding conditions. It will optimize ignition, increase acceleration, and improve fuel efficiency, all while enhancing the longevity of your engine.
