Ultra 40 unsleeved wire is a cost-effective version of Ultra 40 lace wire without heat sleeves. The wire features a Kevlar core, which is four times stronger than other aramid fiber cores, increasing the wire's tensile strength while reducing the center diameter. This thickens the surrounding insulation and increases dielectric strength. With only 40 ohms of resistance per foot, it increases power and fuel economy by adding spark to the plug. RFI/EMI resistant, eliminates stereo feedback and ignition interference.
