The traditional ACCEL combination of yellow wire and red spark plug boots has been added to these SuperStock Spiral Core 5000 Series wire sets, which feature color-matched wire and spark plug boots in blue, black, and red. With only 500 ohms/ft. of resistance, more ignition energy can reach the spark plug, producing a longer-lasting, hotter spark flame kernel. The results is higher performance through improved efficiency, quicker throttle response, and reduced emissions. This 8mm wire’s double silicone construction is rated to 550 degrees F. The high-gloss wire jacket resists moisture, chemicals, and heat extremes for longer life and great looks. The fiberglass braid adds greater pull strength and terminal retention, while the stainless steel spark plug terminals provide excellent long life, electrical conductivity, and corrosion resistance. Both universal and custom-fit applications are available for early and late model cars and trucks.

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 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: The E3.46 spark plugs are 14mm with a 0.750 reach and a gasket seat, making them suitable for a wide range of applications from the 1960s to early 1990s, especially for import vehicles.
