Denso Iridium Power Spark Plugs Set Description
Sold in complete sets (includes all spark plugs for your engine).

DENSO's Iridium power spark plugs help your Import achieve unparalleled performance. Iridium is the biggest breakthrough in spark plug technology since platinum. DENSO Iridium Power spark plugs are currently the best iridium plugs available.

Iridium Power Spark Plugs Key Features:
  • Iridium conducts electricity better than platinum, and is 6 times harder and 8 times stronger than platinum.
  • Ultra-fine 0.4mm diameter iridium center electrode provides superior ignition performance.
  • Utilizes Denso's patented U-Groove technology for better fuel efficiency, improved throttle response, and greater firing energy.
  • Requires fewer volts to fire than any other plug.
Fitment Notes: For every 100 hp you add to your Import's engine, you may go to the next colder step plug.

Gapping Notes: These plugs come pre-gapped and usually do not need to be gapped. Even with small variations in the factory set gap, the ultra-efficient firing power design will compensate for those small variations. If you do decide to gap the plugs, NEVER use a round gapping tool to check or change the gap, and never let any piece of metal touch the iridium center electrode or porcelain. Instead, carefully use needle nose pliers or spark plug gapping tool to bend the ground strap to the desired height, then re-check the gap with a calibrated gapping tool.

Availability: Unless otherwise noted, this product is usually in stock at one of our warehouses, or will ship directly from the manufacturer.
