More voltage, less arcing
The MSD Blaster 3 coils put out 45,000 V, which are 15,000 more than stock. They also have an oil-filled metal canister and will fit stock mounting brackets. The coils have a unique Power Tower that is twice as high as a standard tower. The extra distance prevents secondary arcing between the primary terminals and the coil center. The HEI-style boot and terminal keep the coil wire secure.
