DENSO – Iridium Power Spark Plug (Part No.F100087612ND)

Iridium Power Spark Plug

from

$11.89
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 gruelling 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.

Product Features:
  • Tapered cut, U-Groove ground electrode
  • 0.4mm iridium center electrode
  • 360-degree laser welding assembly process
  • 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.

E3 – DiamondFIRE Automotive Spark Plug: More Power, Saves Gas (Part No.E3.64)

DiamondFIRE Automotive Spark Plug: More Power, Saves Gas

from

$6.99
The Spark Plugs are the product of years of fundamental research in the combustion field. The unique patented electrode configuration of these new The spark plugs increases the amount of combustion pressure created during each power stroke of an engine, which results in a marked increase in power output, fuel economy, and reduced emissions in all gasoline engines. E3.64 is a 14mm, 0.750 reach plug with a gasket seat. It fits a wide variety of late model applications, especially import. E3.64 is widely stocked in automotive retail stores. The automotive plugs have three legs securing the Diamond FIRE electrode to the shell. This allows for excellent heat transfer, and helps to create more turbulence in the cylinder. The patented Diamond FIRE side wire is proven to increase power, reduce fuel consumption and improve hydrocarbon emissions in long-term use.

Product Features:
  • E3’s Diamond Fire edge to edge ground electrode provides maximum performance with increased efficiency and a faster more complete burn
  • Smoother Acceleration & Idle – The faster flame initiated by the The spark plug results in a more complete burn of the ingested fuel charge. More pressure is created against the piston more fuel is put to work
  • Energy – Power output improved up to 6% on average in the typical operating ranges. Results will vary.
  • Efficiency – The “diamond shaped” side wire electrode projects the combustion spark in a way that more quickly ignites the air/fuel mixture, thereby creating a significantly faster and larger flame kernel. The result is that more fuel is put to work durin
  • E3’s patented Diamond Fire Technology provides a cleaner burning combustion, which translates into fuel savings and reduced engine carbon deposits
  • The Spark Plugs are pre-gapped at the factory and cannot be adjusted.
