DENSO 5346 Iridium Power Spark Plug

The DENSO 5346 Iridium Power Spark Plug delivers exceptional ignition performance using DENSO's industry-leading iridium center electrode technology. Engineered for drivers who demand more from their engine, this plug features the world's smallest 0.4mm iridium center electrode — a DENSO exclusive — that concentrates the spark for a more complete, efficient combustion event.

Key Features:

• Ultra-fine 0.4mm iridium center electrode — the world's smallest, for a more focused, powerful spark
• Iridium tip construction — iridium's extreme hardness and high melting point ensure long-lasting durability and consistent performance
• Improved throttle response and fuel efficiency — more complete combustion translates to better power delivery and economy
• Reduced quenching effect — the fine-wire electrode minimizes heat loss for reliable ignition across all RPM ranges
• OEM-quality construction — manufactured to DENSO's precise tolerances for a direct-fit, no-modification installation
• Enhanced ignitability — superior spark energy for easier cold starts and smoother idle

DENSO is a global leader in spark plug technology and the original equipment supplier to many major automakers. The Iridium Power line, referenced by part number 5346, represents the pinnacle of DENSO's spark plug engineering, making it an excellent choice for performance-minded drivers seeking a long-lasting, high-output replacement plug.
