The traditional Accel combination of yellow wire and red spark plug boots has been added to the existing SuperStock Spiral product line, which features color matched wire and spark plug boots in blue, black and red. With only 500 Ohms Per Foot of resistance, more ignition energy can reach the spark plug, producing a hotter, longer-lasting spark flame kernel. The result is higher performance through improved efficiency, quicker throttle response and reduced emissions. This 8 Millimeter wire’s double silicone construction is rated to 550 Degree Fahrenheit. The high gross 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. 550 Degree Fahrenheit Rated Street Driven Applications 8 Millimeter Red, Blue, Black Or Yellow High Temperature Silicone Jacket Resists Moisture, Chemicals And Severe Temperatures High Strength Fiberglass Braid For Added “Pull Strength” Silicone Insulation Eliminates Arcing Stainless Steel Plug Terminals For High Electrical Conductivity And Corrosion Resistance Pre And Post HEI Applications Universal Fit Limited 90 Day Supplier Warranty
