The MSD 8.5mm Super Conductor Spark Plug Wire Set (Model 31559) is engineered to deliver maximum energy to the spark plugs, ensuring efficient ignition of the air-fuel mixture. These wires feature extremely low resistance while effectively suppressing electromagnetic interference (EMI). This manual provides essential information for the proper installation, maintenance, and understanding of your MSD spark plug wire set.
コンポーネントオーバーview
Before installation, familiarize yourself with the components included in your MSD 31559 Spark Plug Wire Set.

This image displays the various components included in the MSD 31559 8.5mm Super Conductor Spark Plug Wire Set. It features a coiled red spark plug wire, a black spark plug boot with 'MSD' branding, a gray 90-degree boot, a small metal terminal, and a black wire crimping tool.
The set typically includes the 8.5mm Super Conductor wire, various spark plug boots (straight, 90-degree, etc., depending on application), and terminals for custom fitment. A wire crimping tool may also be included or required for assembly.
インストール手順
Proper installation is crucial for optimal performance and longevity of your spark plug wires. Always ensure the engine is cool and the battery is disconnected before beginning work.
- 安全第一: 車のバッテリーを外し、エンジンが完全に冷めるまで待ちます。
- 古い配線を取り外す: Remove one spark plug wire at a time from the distributor/coil and then from the spark plug. This helps prevent firing order mix-ups. Note the length and routing of each wire.
- 測定とカット(必要な場合): If assembling custom-length wires, measure the required length for each wire, ensuring it matches the original wire's path without being too tight or too loose. Cut the 8.5mm Super Conductor wire to the appropriate length.
- Install Terminals and Boots: Slide the spark plug boot onto the wire. Strip approximately 1/2 inch of insulation from the end of the wire. Fold the conductor back over the insulation. Insert the terminal into the wire and crimp securely using a proper crimping tool. Pull the boot over the terminal until it seats firmly.
- Connect New Wires: Connect the new MSD spark plug wire to the corresponding spark plug and then to the distributor or coil pack. Ensure a secure connection at both ends. Repeat for all cylinders, one at a time.
- 配線経路: Route the new wires away from hot exhaust components and moving parts to prevent damage. Use wire separators if necessary to maintain proper spacing and prevent crossfire.
- 最終チェック: Double-check all connections and routing. Reconnect the battery.
For specific vehicle applications, consult your vehicle's service manual for detailed spark plug wire routing and firing order information.
動作特性
The MSD 8.5mm Super Conductor Spark Plug Wires are designed to enhance your ignition system's performance through several key features:
- 低抵抗: The copper alloy conductor provides less than 50 ohms per foot of resistance, ensuring maximum spark energy reaches the plug.
- EMI Suppression: A ferro-magnetic impregnated core acts as an effective choke, suppressing electromagnetic interference that can affect sensitive electronic components.
- 耐久性: The conductor core features DuPont Kevlar material for increased tensile strength, while the proprietary outer sleeve resists high heat and abrasion.
- 安全な接続: Stainless steel terminals are designed with dual crimp tabs to securely grip both the wire conductor and the outer jacket.
These characteristics contribute to a more consistent and powerful spark, leading to improved combustion efficiency.
メンテナンス
Regular inspection and proper care will extend the life and performance of your MSD spark plug wires.
- 目視検査: Periodically inspect wires for signs of wear, cracking, fraying, or burns, especially where they pass near hot engine components or sharp edges.
- 接続チェック: スパークプラグとディストリビューター/コイルパックの両方に、すべてのブーツがしっかりと固定されていることを確認してください。接続が緩んでいると失火につながる可能性があります。
- クリーニング: Keep wires clean from oil, grease, and dirt. Use a mild automotive cleaner if necessary, and avoid harsh solvents that could damage the insulation.
- ルーティング: Confirm that wires remain properly routed and separated to prevent contact with hot surfaces or moving parts.
トラブルシューティング
If you experience issues after installing your spark plug wires, consider the following common troubleshooting steps:
- エンジン不調: Check for loose connections at both the spark plug and the distributor/coil. Ensure the correct firing order was maintained during installation. Inspect wires for physical damage or arcing.
- アイドリングが不安定/パフォーマンスが低い: Verify that all wires are fully seated and that no wires are pinched or damaged. Confirm that the correct length wires were used and are not stretched.
- 無線干渉: While MSD Super Conductor wires are designed for excellent EMI suppression, ensure proper grounding of all ignition components. Check for any unshielded electrical components near the wires.
- 始動困難: Ensure all connections are secure and that the spark plugs themselves are in good condition and correctly gapped.
If problems persist, it is recommended to consult a qualified automotive technician or contact MSD technical support.
