  • Can I use solid core spark plug wires with my MSD Ignition?

    No. Solid core wires produce excessive Electro Magnetic Interference (EMI) which can interfere with the operation of MSD ignition controls. It is recommended to use helically wound suppression wires, such as the MSD 8.5mm Super Conductor.

  • How do I register my MSD product for warranty?

    You can register your MSD product online at the official MSD Performance registration page (www.msdperformance.com/registration) to ensure warranty coverage and product support.

  • What is the gap setting for spark plugs when using MSD Ignition?

    MSD recommends following the engine builder or manufacturer specifications as a starting point. However, the gap can often be opened in 0.005-inch increments to test for performance improvements with the stronger MSD spark.

  • How do I select the correct cylinder count on my MSD ignition box?

    Many MSD ignition units (like the 6AL) are set for 8-cylinder engines by default. For 4 or 6-cylinder applications, you typically need to cut specific wire loops (Red or Blue) located on the side of the unit or adjust rotary dials, as detailed in your specific product manual.
