DENSO Iridium Power® Spark Plug

DENSO Iridium Power® spark plugs represent a performance breakthrough. The laser-welded center electrode is only 0.4mm in diameter – the slimmest iridium electrode in the industry. The taper-cut side electrode complements the design, delivering reliable spark energy under the most grueling pressures and temperatures.

DENSO engineers used the power of this miraculous metal to produce an iridium center electrode that is only 0.4mm in diameter. With its superior thermal qualities, this whisker-fine electrode is capable of taking the most extreme heat and punishment.

This breakthrough was matched to one of DENSO's most famous innovations, the patented U-Groove ground electrode. The combination of these two features resulted in the Iridium Power® plug, one of the most advanced and innovative spark plugs on the market.
Features
  • Tapered cut, U-Groove ground electrode
  • 0.4mm iridium center electrode
  • 360-degree laser welding assembly process
Benefits
  • Required ignition voltage reduced
  • Unsurpassed center electrode durability
  • Available for many performance and power sports applications, including Corvette, Viper, and Harley-Davidson
The Iridium Power® plug delivers greater spark energy while demanding significantly less secondary required voltage from the ignition system.

Warranty Information: 12 month - 12,000 mile limited warranty against defects in material and workmanship

"I put these in my Vtwin motorcycle in November. In March the bike quit running. Took it to a dealer and all he had to do to get it running was put normal plugs in it. Hope nothing permanently damaged. Told a friend about it after the fact and he described the same trouble with his Chevy truck. His mechanic said they burn extra hot and mess up the computer sensors." posted by: GOC Sensei on March 12, 2014

"I replaced my 10 year old ----- Platinum +4 spark plugs which I was still getting 38 MPG highway with over 225k miles. After replacing with E3, my MPG fell to 32 MPG highway. Disappointed to say the least. I'm returning and going back to a new set of +4's." posted by: MJ on December 19, 2011 view all 8 reviews
