Product Details

The MSD 31543 Super Conductor Spark Plug Wire Set is engineered specifically for small block Chevy sprint car applications where clearance is critical. This close-fit design features 8.5mm spiral core conductors that deliver maximum spark energy while maintaining a compact profile around headers and chassis components.

Key Features:

  • 8.5mm Super Conductor design with spiral-wound core for superior EMI/RFI suppression
  • Low-resistance construction (less than 500 ohms per foot) ensures maximum voltage transfer to spark plugs
  • Close-fit routing optimized for SBC sprint car engine bay clearance
  • Durable black silicone jacket withstands temperatures up to 600°F
  • Helical stainless steel magnetic core prevents voltage leakage
  • Custom-fitted terminals provide secure connections to distributor cap and spark plugs
  • Race-proven design trusted by professional sprint car teams

MSD Super Conductor wires utilize a proprietary conductor system with a ferro-magnetic impregnated center core surrounded by a copper alloy winding. This construction delivers 20-30% lower resistance than conventional spiral core wires while providing excellent spark isolation. The black silicone jacket protects against heat, chemicals, and abrasion in demanding racing environments.

Parts were actually in-stock unlike every other retailer I tried. Quick shipping too.

Best price for a superior product and no gimmickry or BS about the product.

Did not mention anything about mounting hardware, will cancel sale if no mounting kit, thank you

Good price, shipping discount--does not match what Google sees, but ok.

Very satisfied! My intake shipped on Friday and I received it on Tuesday. Not only super fast shipping, but a great deal to boot!

Easy transaction

Good

quick, easy, good price

Found the lowest price on my fuel pump and saved more than 50% from other sites.

Very fast checkout

After weeks of shopping around, I was able to find the best price from Autoplicity. The ordering process was very simple since I had the option to pay through my Amazon account. Great experience.

Not sure if this is exactly what I need.
