Direct fit ProCoil has identical dimensions as stock coil for easy, bolt-on installation. Generates more spark energy than stock or aftermarket brands; the hotter spark ensures complete combustion to improve idle, acceleration and fuel economyPrimary Windings consist of large diameter, high temperature copper magnet wire that allows high primary current flow for maximum energy storageMagnetic Core is manufactured from high silicon M36 magnetic steel that's specifically tuned for maximum, spark energySecondary Windings incorporate high turns ratio, low oxygen, extra fine copper wire for maximum spark outputHigh-Temperature Epoxy is filled under vacuum to ensure complete impregnationDouble-Layer Insulation provides extra protection against "arc-thru"OE-Style Terminals offer plug-in wiring installationDurable Alkyd Case resists carbon-trackingApplication Guide Click Here
