Moroso Ultra 40 race wire is the standard in high performance ignition wire. With optimized EMI/RFI resistance, Moroso wire is used in the highest level of racing applications from dual mag top fuel cars thru NASCAR Sprint® Cup Series. Moroso Ultra 40 wire sets the performance standard. At 8.65 Millimeter or 7 Millimeter in diameter and 40 Ohms of resistance per foot, Moroso Ultra 40 race wire incorporates a highly engineered spiral wound conductor. This maximizes energy transfer and minimizes electro magnetic interference (EMI) and radio frequency (RF) interference noise. This combination results in the ultimate ignition wire for any race application! The most powerful wire ever!

For custom applications, Blue Max™ spiral core universal fit sets are the way to go. Available in 8 Millimeter, 800 Ohm or our extra thick 11 Millimeter 800 Ohm, these sets are terminated at the plug end only and comes with enough wire length and terminals to fit HEI or Non HEI distributors. Comes with coil wire is when required. There’s even a wire stripping tool to simplify the termination. And like all Moroso Blue Max™ wire, each is individually tested for unsurpassed quality control.
