E3 - DiamondFIRE Automotive Spark Plug: More Power, Saves Gas (Part No. E3.74)
DescriptionThe 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. E3.74 is a 14mm, 1.000 reach plug with a taper seat. It fits a wide variety of late model applications, especially Ford applications. 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 during each combustion cycle.
- 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.

NGK - OE Series Laser Iridium Spark Plug: Fine Wire Tip Design, ILTR5E11 (Part No. 91418)
DescriptionNGK Laser Iridium spark plugs offer the best combination of performance and longevity. Engineered specifically for OE applications, Laser Iridium spark plugs are tested to the highest standards to ensure quality and durability. Iridium tipped center electrode provides durability six times harder than platinum. NGKs high grade pure alumina ceramic and 98 percent pure copper core prevents the spark plug from overheating while providing reliable starts. Most Laser Iridium spark plugs feature a platinum pad on the ground electrode for even wear in distributor less ignition systems.
Product Features:- ACTUAL OE or EQUIVALENT DESIGN: OEM quality construction fine wire iridium alloy center electrode provides consistent performance
- IRIDIUM ALLOY CENTER ELECTRODE: Iridium's density (6x that of platinum) and extremely high melting point is perfect for modern high efficiency engines
- PLATINUM TIP GROUND ELECTRODE: Unless OE specified, platinum protection at the ground electrode provides excellent ignitability and service life
- SOLID COPPER CORE: 98% pure copper core offers superior heat dissipation, conductivity and ultra wide heat ranges
- TRIVALENT METAL PLATING: Delivers superior anti-corrosion and anti-seizing properties, ensuring ease of installation and removal
- RECOMMENDED USAGE: Best for vehicles with OE fine wire iridium alloy plugs

DENSO - Iridium Power Spark Plug (Part No. F1000177171ND)
DescriptionDENSO 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.
