LS Coil D510C/D514A

The LS Coil D510C/D514A is a high-performance ignition coil pack engineered for LS-series engine swaps and OEM LS platform vehicles. Whether you're building a classic muscle car restomod, a modern performance street machine, or maintaining factory LS power, this coil delivers the spark timing precision required for efficient combustion across the entire RPM range. LS platform engines have become the go-to choice for engine builders and enthusiasts worldwide, and reliable ignition components like this coil are critical to maximizing both reliability and power output.

This coil pack is designed to handle the demanding electrical requirements of LS engines, providing consistent spark energy needed for proper fuel ignition under boost, high RPM operation, and variable load conditions. The compact design—measuring 4.35 x 2.4 x 4.8 inches and weighing just 0.67 lbs—allows flexible mounting in tight engine bay installations without compromising cooling or serviceability. Allstar Performance's reputation for quality manufacturing ensures this coil meets strict OEM standards for voltage output and thermal stability, preventing misfire issues that can result from weak or inconsistent ignition signals.

Technicians and builders use the LS Coil D510C/D514A for complete engine swaps, performance tuning projects, and replacement maintenance on Gen III, Gen IV, and Gen V LS platforms. Installation is straightforward on most LS configurations, though proper connector seating and wire routing prevent cross-fire and ensure each cylinder receives independent spark timing. If you're experiencing hard starts, rough idle, or cylinder misfires on an LS-powered vehicle, this coil pack is an essential diagnostic and replacement component that restores reliable ignition performance.
