Product Details

The DENSO 3174 (PK16PR-P11) is a premium double platinum spark plug engineered to deliver superior ignition performance and extended service life. Unlike conventional platinum plugs that feature platinum only on the center electrode, this advanced design incorporates platinum on both the center and ground electrodes, providing enhanced resistance to corrosion and erosion for consistent spark performance over time.

Key Features:

  • Double platinum construction on both center and ground electrodes for maximum durability
  • Capable of extended operation in excess of 60,000 miles
  • 360-degree laser weld for superior structural integrity
  • 14mm thread size with 0.750-inch (19mm) reach
  • Built-in resistor for reduced electromagnetic interference
  • Premium shell construction with precision machine-rolled threads
  • Superior thermal conductivity for optimal heat dissipation
  • Reduced secondary voltage requirement for improved ignition efficiency

Manufactured to the strictest OE performance, durability, and emissions standards, the DENSO 3174 spark plug ensures reliable starting, smooth operation, and optimized fuel efficiency. Ideal for distributorless ignition systems (DIS) and applications where spark plugs are difficult to access and change frequently.
