DENSO 5713 Iridium Racing Spark Plug - IW01-24

The DENSO 5713 Iridium Racing Spark Plug (IW01-24) is an elite performance spark plug engineered for racing and highly tuned engines. Designed with technology proven in Formula 1 racing, this plug delivers ultimate acceleration and reliability under the most demanding conditions.

Advanced Electrode Technology:

• Ultra-fine 0.4mm iridium-rhodium alloy center electrode requires up to 5,000 volts less to fire, producing the hottest and most concentrated spark
• 100% pure platinum 0.8mm ground electrode resists melting and reduces wear under severe racing conditions
• Patented 360-degree laser welding process secures the iridium tip to withstand extreme stress

Race-Ready Construction:

• Hardened insulator is 20% stronger than standard plugs for hardcore racing applications
• Silicone oil-coated insulator repels moisture and carbon buildup to prevent resistance loss
• Patented self-cleaning electrode design burns off carbon deposits, restoring electrical resistance
• Five-rib insulator design prevents flashover under high voltage conditions
• Purified alumina powder insulator provides exceptional strength and thermal conductivity

Performance Benefits:

• Handles extreme compression and boost levels with superior reliability
• Dramatically improves combustion conditions for increased engine output, power, and torque
• Greatly reduces non-firing and misfires under a variety of conditions
• Machine-rolled threads prevent seizing or cross-threading during installation and removal
• 100% pre-fired to assure the highest quality possible

Technical Specifications:

• Thread Size: 14mm
• Reach: 19mm (0.748 inches)
• Seat Type: Flat seat
• Heat Range: 24
• Resistor: Yes (monolithic resistor reduces electrical interference)
• Terminal: Removable attachable terminal compatible with most plug wires worldwide

Popular for street and off-road motorcycles, scooters, ATVs, UTVs, snowmobiles, personal watercraft, and high-performance automotive applications. This is a no-compromise racing spark plug for the serious enthusiast demanding maximum performance.
