    The most powerful wire ever!
    Highest spark energy transfer. Highest EMI/RFI suppression. Highest horsepower gain. The Ultra 40 Race Spark Plug Wire's extra insulation extends spark plug wire life against exhaust header heat, chaffing and contaminants. Closely woven fiberglass, impregnated with high-voltage-leak resistant silicone adds up to 8,000 volts of extra insulation. At 40 ohms of resistance per foot, Moroso Ultra 40 Race Spark Plug Wire incorporates a spiral wound nickel/copper alloy conductor wrapped at the optimum ratio to produce the highest level of spark energy while producing the lowest level of electromagnetic and radio frequency interference. The Kevlar core is four times stronger than other aramid fibers cores, allowing an increase in the tensile strength of the wire while reducing the center diameter and at the same time increasing the surrounding insulation resulting in greater dielectric strength.

    Features:
  • The standard in high performance ignition wire
  • Optimiized EMI/RFI resistance
  • Used in the highest level of racing applications ranging from dual mag Top Fuel Cars thru NASCAR Sprint Cup Series
  • 7mm or 8.65mm diameter wire with 40 ohms of resistance per foot
  • Incorporates a highly engineered spiral wound conductor
  • Maximizes energy transfer and minimizes electro magnetic interference (EMI) and radio frequency (RF) interference noise

    Note: Straight plug boot kits are bendable to 45 Degrees.

  • 73833 - Moroso Ultra 40 Race Spark Plug Wire Sets is rated 5.0 out of 5 by 2.
    Rated 5 out of 5 by from Best wire on the market!! I have tried a lot of wires over the years of racing and time after time I come back to Moroso Ultra 40's. These are the best performing wires on the market bar none.Fyi you have to make up one end of the coil wire on the custom 302 set although it's not hard to do I did want to mention it.

    Rated 5 out of 5 by from Nice Great fit and positive feel when attaching to cap or plugs. One note that if you do not like them running over the valve covers don't buy the fitted set, get the build your own kit.
