The DENSO Iridium Long Life spark plug was specifically designed for long service life and consistent performance in the latest, most advanced production cars DENSO’s patented iridium alloy is more durable than even platinum, allowing the center electrode to be shrunk to only 0.7mm in diameter. This produces a dramatic improvement in ignitability and spark plug life. Closely related to platinum and exhibiting even tougher qualities, the rare metal iridium is an ideal material for spark plugs. A fine-wire, 0.7mm iridium center electrode is 360-degree laser welded in place using an exclusive DENSO process, and then matched to a platinum ground electrode. This pair of precision-formed, premium-metal electrodes dramatically extends the plug’s useful life.

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. E3.68 is a 14mm, 1.000 reach plug with a gasket seat. It fits a wide variety of late model applications, especially Hemi applications. E3.68 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.
• Wide Compatibility: E3.68 spark plugs are 14mm with a 1.000 reach and a gasket seat, fitting a wide variety of late model applications, especially Hemi engines.
• Enhanced Heat Transfer: The three legs securing the Diamond FIRE electrode to the shell ensure excellent heat transfer and create more turbulence in the cylinder for better combustion.
• Widely Available: E3.68 spark plugs are widely stocked in automotive retail stores, making them easily accessible for consumers.

Nippon Reinz Spark Plug tube Seal withstands high and low temperatures to provide a reliable seal with minimal tightening. Spark Plug tube Seals are increasingly produced with profiles and not flat; that is, the gasket surface is provided with beads or lips. Now, instead of the entire gasket surface, only the profile needs to be pressed, that is, the sealing bead or sealing lip, and just a slight amount of bolting force produces sufficient deformation and adaptation.

Product Features:

• Stays cool at temperature up to 1800F
• Designed to seal minor surface irregularities
• No re-torque required
• Teflon® coating optional

Fel-Pro gaskets offer 100% vehicle sealing with application-specific materials to give you sealing solutions with the performance and durability professionals trust
