Speedmaster PCE382.1032.01 Ignition Coil-On-Plug D585 for GM LS

GM Ls Ignition Coil On Plug (D585) Failure or poor performance from a coil can result in a misfire, a rough-running, hard-starting engine, and excessive emissions. PCE's ignition coils provide the performance needed to help keep vehicles running the way that they were designed. These coils have corrosion-protected laminations to protect coils from the harsh operating environment. High output technology coil produces up to 70% more spark energy than stock coils with outstanding reliability Large gauge wire windings for maximum spark current and voltage with better heat dissipation at high rpm
