Product Details

The DENSO 3501 is a premium iridium spark plug engineered for extended service life and superior performance. Featuring an ultra-fine iridium center electrode, this spark plug delivers consistent ignition, improved fuel efficiency, and reduced emissions compared to conventional copper spark plugs.

Key Features:

  • Iridium center electrode for maximum durability and longevity
  • Manufactured to strict OE performance and emissions standards
  • Enhanced ignitability for quicker starts and smoother acceleration
  • Superior heat dissipation for reliable performance under extreme conditions
  • Reduced voltage requirement for optimal fuel economy
  • Extended service intervals reduce maintenance costs

DENSO's iridium technology provides a concentrated spark that ignites the air-fuel mixture more efficiently, resulting in better throttle response and engine performance. The iridium material is six times harder and eight times stronger than platinum, ensuring long-lasting performance mile after mile.
