Product Details

The Moroso 9772M Mag-Tune spark plug wire set is purpose-built for modified Ford small block engines running HEI-style ignition systems. Featuring a 135-degree plug boot configuration, these wires are designed to clear headers and tight engine bay obstacles commonly found in performance and racing builds.

Key Features:

  • 8.0mm diameter wire construction for superior insulation and durability
  • Spiral core (mag-wound) design suppresses RFI/EMI interference to protect sensitive electronics and sensors
  • 135-degree spark plug boots for clearance in tight or modified engine bays
  • HEI distributor compatible — fits high-energy ignition setups
  • Black silicone outer jacket resists heat, oil, abrasion, and moisture
  • Fully assembled and ready to install — no cutting or crimping required
  • Designed specifically for Ford small block modified applications
  • Sold as a complete kit with all cylinders included

Moroso's Mag-Tune wires deliver reliable spark energy transfer while minimizing electromagnetic interference — making them an ideal upgrade for street/strip and competition vehicles. The spiral-wound core provides excellent suppression without sacrificing ignition performance, keeping your engine running cleanly at high RPM.

fast ordering

My second time ordering from Autoplicity. I price shop online and Autoplicity had the lowest price both times. Fast ship with email notifications. Autoplicity will now be my "First" site I go to for my auto accessories. Great job Autoplicity.

Easy shopping

Super fast shipping, Lowest price I could find anywhere. A+++++++++++++++

The site does not inspired confidence due to the current look and feel. However the delivery was fast and the issue with ordering was resolved in matter of days. The only down side was that on of the parts did not match the original part of my vehicle. As

Ordered a hard to find in Lagos fuel sender for my 1998 Benz c280 and i had it delivered on time for delayed reapirs. Order #6886

Cheapest prices I found online! Ordered at 4:30 on a Thursday afternoon and had 'em waitin' on my doorstep by SATURDAY!
