Product Details

The DENSO 5004 is a premium iridium spark plug engineered to deliver superior ignition performance and extended service life. Featuring a 0.4mm iridium center electrode, this plug provides exceptional durability and fuel efficiency compared to conventional copper or platinum plugs.

Key Features:

  • Ultra-fine 0.4mm iridium center electrode for improved ignitability and throttle response
  • Platinum ground electrode enhances wear resistance and longevity
  • 360-degree laser welding for maximum durability under extreme conditions
  • Purified alumina powder insulator prevents flashover and misfires
  • Trivalent metal plating provides superior anti-corrosion and anti-seizing properties
  • 14mm thread diameter with 5/8" (16mm) hex size

DENSO's iridium technology concentrates spark energy at the electrode tip, reducing the voltage required for ignition while improving combustion efficiency. This results in smoother engine operation, better fuel economy, and reduced emissions. Ideal for both OEM replacement and performance applications across a wide range of automotive engines.
