MSD Blaster OEM Replacement Coils
When it comes to late model performance parts, nothing beats bolt-on and direct connection components—especially when they improve performance like these new replacement MSD Blaster ignition coils. They're designed with improved materials and windings to produce a stronger spark. This improved spark helps burn the fuel mixture more efficiently, resulting in smooth idle and heightened mid-range rpm power. Choose the OEM replacement designed for your year/make/model application.
