I out this coil on an older Jeep CJ7 that I restored and wanted a little more power. Why you can't FEEL the difference I can tell that the engine starts a little quicker, idles better. Facing facts that this Jeep is more for off road fun than drag racing, its nice to know that I have a coil that will never be overwelmed by whatever the little 304 V-8 needs as far as spark. I will soon be getting one for my C4 Corvette to replace the stock one. It is about the same price as OEM (+/- $50)

None. Installation just like stock. I also used their wires to complete the red look. Good quality stuff.

Worthwile investment, escecially if you need an new coil anyway. Trash thay OEM unit and get more volts.

Accel. They seem just like any other mass produced part - cheap.

Costs same as stock coils, higher voltage output.

No noticable improvements.

I have used the MSD Blaster coils in 2 cars now. There is really no noticable difference between the high-output coil and the stock one. MSD claims their coils put out 50,000 volts compared with the stock units which put out around 10-20,000 (can't remember exactly). The coil is a good value ($30 same as a stock coil), but only if you need to replace your existing unit.

Inexpensice, looks high end, outstanding customer support from MSD.

IT really didn't seems to do a lot, except SLIGHTLY lower exhaust emissions and increase fuel economy.

Used this in my 79 Datsun 280zx auto. ONly thing it did performance wise was let my auto rev sliughtly higher, therefore increasing the power band. But since it's so inexpensive, why buy stock? This looks higer end anyway...
