ACCEL Pro-25 race wire was developed and tested by racers. It has a Ferro-spiral core wound to allow maximum spark energy at only 25 ohms per foot and still suppress RFI noise. The wire features a double silicone construction rated at over 600 degrees F. The high gloss red silicone wire jacket not only looks great but also resists extreme heat, petrochemicals, ozone and moisture better than any race wire on the market. This allows longer life and better durability. The high-density silicone insulation provides greater dielectric strength and eliminates arcing. The all Kevlar stranded inner core and fiberglass braiding adds greater pull strength and terminal retention. The stainless steel and brass terminals provide unsurpassed electrical conductivity and excellent corrosion resistance.
