Ngk Spark Plug DCPR6E 3481

Description

NGK Spark Plug - DCPR6E

Part No.: 37-DCPR6E
Key Features:

  • Copper Core: NGK's copper core design allows for faster heat dissipation, keeping the electrode and insulator tip cool. This prevents overheating and helps maintain performance under high stress.
  • High-Performance Compatibility: The DCPR6E plug is built for high-performance engines, offering a raised pre-ignition rating and improved conduction with a long-nose insulator.
  • For Twin Cam Models: For 1999-up Harley-Davidson Twin Cam models, this plug is one heat range hotter than the standard plug (standard plug is DCPR7E).

Specifications:

  • Heat Range: 6 (Perfect for engines operating at moderate temperatures).
  • Thread Size: 12mm (common for many motorcycle and small engine applications).
  • Gap: 0.028" (0.7mm), providing the optimal spark for reliable ignition.
  • Hex Size: 5/8" (16mm) for easy installation and removal.
  • Type: Resistor, designed to reduce electrical noise and interference in the ignition system.
  • Terminal Type: Stud terminal threads for secure connections.
  • Weight: 0.06 lbs.

Applications: This spark plug is compatible with various Harley-Davidson motorcycles, especially Twin Cam models, and other models with high-performance engines:

Harley-Davidson:

  • 2000-2017 Dyna Convertible, Fat Bob, Low Rider, Street Bob, Super Glide, Super Glide Custom, Switchback, Wide Glide, and Electra Glide models.
  • This plug is ideal for those needing a higher temperature rating for performance improvement.

Benefits:

  • Improved Heat Dissipation: Copper core design helps efficiently remove heat, ensuring longer-lasting and stable performance.
  • Optimized Performance: Designed to meet the demands of high-performance engines, reducing the risk of pre-ignition and improving overall engine efficiency.
  • Durability: NGK plugs are built with high-quality materials, including alumina silicate ceramic insulators and copper cores, which improve strength and heat transfer.

Construction:

  • Copper Core: Provides faster heat removal and longer lifespan compared to conventional plugs.
  • Triple Seals: Prevents internal leakage, ensuring better performance in demanding environments.
  • Corrugated Ribs: Prevent flashover, maintaining a consistent and reliable spark under all conditions.

This spark plug is designed to deliver optimal performance in high-performance engines, particularly Harley-Davidson motorcycles, improving acceleration, fuel efficiency, and overall engine performance.
