DENSO 5751 Iridium Racing Spark Plug - IKH01-31

The DENSO 5751 IKH01-31 is an elite racing spark plug engineered for serious enthusiasts seeking maximum performance during high-stress driving conditions. This plug features a 0.4mm iridium-rhodium alloy center electrode that requires up to 5,000 volts less to fire, producing an exceptionally hot and concentrated spark for improved combustion efficiency.

Key Features:

• Ultra-fine 0.4mm iridium-rhodium center electrode and 100% pure platinum 0.8mm ground electrode
• 20% stronger insulator material designed specifically for hard-core race applications
• Patented 360-degree laser welding secures the iridium tip to withstand severe conditions
• Patented spark cleaning pocket burns off carbon deposits, restoring electrical resistance
• Monolithic resistor blocks electrical noise that may affect electronic devices
• Silicone coated insulator surface prevents moisture and carbon buildup
• Burnished nickel plating provides corrosion resistance and prevents thread seizing
• 14mm thread size, 26.50mm reach, flat seat design

This spark plug dramatically improves combustion conditions, increasing engine output for superior power and torque while enhancing overall engine efficiency. Ideal for street and off-road motorcycles, scooters, ATVs, UTVs, snowmobiles, personal watercraft, and high-performance automotive applications.
