How do I choose the right MSD spark plug leads for my LS Chevrolet or Holden Commodore?

Great question! Our collection features MSD spark plug leads specifically designed for popular engines like LS Chevrolet, Holden Commodore, and classic V8 applications. To pick the right leads, match your engine model (e.g., LS1, LS2, VB-VZ Commodore) and check the product fitment details in each listing. If you’re running headers or have performance upgrades, we recommend the 8.5mm MSD Super Conductor leads for better spark delivery and engine efficiency. Not sure? Get in touch with our team with your car’s specs and we’ll make sure you get the perfect fit.

What are the benefits of upgrading to MSD spark plug leads compared to standard ones?

Upgrading to high-performance MSD spark plug leads means you’re getting superior spark energy, better fuel ignition, and improved throttle response. These leads use thicker insulation and high-conductivity materials that reduce misfire and voltage loss, especially on modified or high-compression engines. You’ll notice smoother idling, more reliable starting, and increased durability compared to factory leads. If you want to maximize your performance ignition system, MSD is the go-to brand trusted by racers and enthusiasts alike.

How do Proflow heat shields help when upgrading ignition parts?

Proflow heat shields are designed to protect your spark plug leads and boots from extreme heat, which is common when you have performance headers or a tuned engine. By shielding your leads, these heat wraps prevent heat soak and premature wear, extending the life of your ignition parts and ensuring consistent performance. For Holden Commodores, LS engines, and classic V8s with tight engine bays, Proflow heat shields are a smart, affordable upgrade to keep your performance ignition running cool and reliable.

Can I install these spark plug leads and heat shields myself, or do I need a mechanic?

Absolutely, most car enthusiasts can install MSD spark plug leads and Proflow heat shields at home with basic tools. The leads come pre-terminated or universal, allowing for easy routing on LS Chevrolet, Holden Commodore, and V8 engines. You’ll just need to remove your old leads, match the new ones by length and cylinder, and clip them in securely. Proflow heat shields simply slide over the leads before connecting to the plug. Clear instructions are included, but if you run into any trouble, our tech team is just a message away.

Will these performance ignition products fit my engine if I have aftermarket headers or engine mods?

Yes! Our MSD spark plug leads and Proflow heat shields are designed with high-flexibility boots and robust construction, making them ideal for cars with aftermarket headers or modified engines. The universal and custom-fit options accommodate a wide range of LS Chevrolet, Holden Commodore, and classic V8 applications—even where space is tight. Upgrading your ignition with these premium components ensures you get reliable spark delivery and protection, no matter how wild your build is.
