Product Details

The Moroso 9872M Mag-Tune spark plug wire set delivers reliable ignition performance for modified Ford small block engines. This pre-assembled kit features high-quality 8.0mm spark plug wires designed specifically for HEI (High Energy Ignition) distributor systems.

Key Features:

  • 8.0mm spiral core construction for superior spark energy and EMI/RFI suppression
  • 135-degree spark plug boots for tight clearance applications and professional appearance
  • Black silicone jacket resists heat, chemicals, and abrasion for long service life
  • Pre-assembled complete kit for Ford small block modified applications
  • HEI-compatible terminals ensure secure connections at distributor and plugs
  • Spiral core design reduces radio frequency interference while maintaining low resistance

Moroso Mag-Tune wires are engineered for enthusiasts who demand race-proven components with reliable street performance. The 8mm wire diameter provides excellent spark energy transfer while the spiral core design maintains proper suppression for electronic components.

Great product and half the price of any one else I've shopped would recommend this to everyone.

Processed and shipped out very quickly. I love when a website delivers! It was the best deal on the internet AND they gave free shipping! I will definitely do future business with Autoplicity. Thanks!

Good price, fast shipping. Will buy again

I was very happy with Autoplicity and my order of the MMRAD-MIA-90X Mishimoto radiator for my Miata. I am in the process of building a Spec-Miata for racing and trying to keep the costs down. I found Autoplicity to have the best prices on the net. I received the rad real quick. There was a problem with the radiator but the guys at Autoplicity were easy to work with and I am expecting the new radiator in a week or so.
