  Ultra 40 un-sleeved wires are a cost effective version of the Ultra 40 Race Wire without heat sleeving. Wires feature a Kevlar core, four times stronger than other aramid fiber cores, that increases the tensile strength of the wire while reducing its center diameter. This allows for the surrounding insulation to be thicker, resulting in greater dielectric strength. With only 40-ohms of resistance per foot these wires will increase power and fuel efficiency by bringing more spark to the plug. RFI/EMI resistant to eliminate stereo response or ignition interference.Ultra 40 Unsleeved Plug Wire Set
