Sultans Of Spark Coils Bring Big Voltage Gains To LS Engines

Performance Distributors has been in the ignition game for a long time, and if there’s one thing they understand, it’s that spark matters… A lot. Now, the company, well known for its Davis Unified Ignition systems, is bringing that experience to the LS crowd with a product that’s about as subtle as its name: Sultans Of Spark.

To be perfectly honest, the name fits. Sultans Of Spark (SOS) coils are designed to fit 1997–2024 GM LS-based engines with the simple goals of delivering more voltage, lighting the mixture harder, and getting more out of every combustion event. Compared to a factory coil, an SOS unit brings a noticeable bump in output, providing 28,000 volts during the acceleration phase versus roughly 21,000 volts.

That’s not a small jump. In real terms, that’s an extra 7,000 volts per coil, or 56,000 additional volts across the engine. The payoff is faster starts, a smoother idle, and sharper throttle response when you lean into the go pedal. That means SOS coils aren’t the kind of upgrade that just shows up on a dyno sheet. You can actually feel the difference every time you drive your vehicle.

One of the biggest advantages of these coils is the ability to open up the vehicle’s spark plug gaps to .065-inch. That wider gap creates a larger spark kernel inside the combustion chamber, which helps burn the air/fuel mixture more completely. More complete combustion means better efficiency. And, as we all know, better efficiency generally translates to more power and cleaner operation.

But here’s where Performance Distributors really got it right: this isn’t a complicated upgrade. Every Sultans Of Spark coil is built to OEM dimensions. Not only do they bolt directly in place using factory brackets, but they also plug right into your existing wiring. Installation requires no custom mounts, no harness modifications, and no headaches. Enthusiasts can literally just swap them in and go!

Construction-wise, Performance Distributors definitely didn’t cut corners. Every SOS coil features brass terminals for improved conductivity and corrosion resistance. Every coil also includes high-quality thermal epoxy leads that help manage heat and vibration–two things LS engines are no strangers to. It’s also important to point out that SOS coils are fully compatible with flash tuners and programmers, so you can integrate them into just about any existing setup without fighting your electronics.

For LS enthusiasts, installing Sultans Of Spark coils is one of those upgrades that just makes sense. It’s simple, it’s effective, and it improves the way your engine behaves across the board, not just at wide-open throttle. Looking to squeeze a little more out of your setup without tearing into the engine? Performance Distributors now offers one of the easiest ways to get it done!
