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 coils. They are designed with improved materials and windings to produce a stronger spark. This improved spark helps burn the fuel mixture more efficiently, resulting in a smooth idle and improved mid-range rpm power.
