LS Coil D581

The LS Coil D581 by Allstar Performance is a precision ignition coil specifically engineered for LS-series engine swaps and high-performance builds. This coil is ideal for those looking to install an LS engine into a classic vehicle or upgrade a modern LS platform, providing reliable spark energy for consistent ignition across various RPM ranges.

Designed to meet the demands of LS architecture, the LS Coil D581 offers strong secondary voltage output and fast saturation for precise timing control. Its compact size of 4.4 x 2.4 x 4.75 inches and lightweight construction at 0.71 lbs facilitate straightforward installation, whether using stock LS valve covers or custom setups. This coil is built to withstand the heat cycles typical of engine bay environments, ensuring consistent performance across varying fuel qualities and altitudes.

Builders working on carbureted LS conversions, fuel-injected retrofits, or naturally aspirated to supercharged platforms will find the D581's ignition characteristics beneficial. While installation is designed to be user-friendly, some setups may require tuning or diagnostic equipment for optimal performance. This coil is a reliable choice for enhancing the ignition system in LS engine applications.
