Technical Specifications:

  • Brand: MSD Ignition (Holley Performance)

  • Part Number (MPN): 31229

  • Product Type: 8.5mm Super Conductor Spark Plug Wire Set (Universal V8)

  • Wire Color: Red

  • Core Material: Copper Alloy (Helically wound around a ferro-magnetic core)

  • Resistance: Ultra-low 40-50 Ohms per foot

  • Spark Plug Boot Style: 90° Angle (Pre-installed)

  • Distributor Boot Style: 90° Angle (Included, unassembled)

  • Distributor Terminal Style: HEI / Male (Included, unassembled)

Performance & Fitment Features:

  • Universal Cut-to-Fit Design: This is NOT a direct drop-in wire set. The spark plug boots are pre-installed, but the distributor ends are left open. The kit includes extra-long wires (up to 56"), allowing you to route them perfectly away from exhaust headers before cutting them to your custom length.

  • Important Fitment Warning (Distributor Cap): This kit includes HEI (Male) style distributor terminals only. It is designed for late-model HEI caps, Ford Duraspark caps, or MSD Cap-A-Dapt kits. It will NOT fit traditional points-style "Socket" (Female) distributor caps without purchasing separate terminals.

  • Maximum Spark Energy: Engineered with the lowest resistance of any helically wound wire on the market, delivering maximum voltage from the coil to the spark plug without radio frequency interference (RFI) that disrupts EFI systems.

  • Hardware Included: Includes all necessary HEI distributor terminals, 90° boots, and an MSD Mini-Stripper-Crimper tool for assembly.

Federal Emissions Compliance:

  • Emissions Code: 5 (Replacement Part)

  • Status: This is a direct physical replacement/upgrade component that does not alter factory emissions output. It is strictly legal for sale, installation, and street use in all 50 US states, including California. No CARB Executive Order (EO) is required.
