Racers have know for a long time that the only way to produce maximum horsepower on a Honda/Acura engine is to get rid of the weak coil mounted inside the cap. MSD's modified caps are specially constructed to allow the use of an external coil such as an MSD Blaster Series Coil. An 8.5mm Super Conductor wire and crimp tool are supplied.

Extreme Power Caps
The Extreme Power Honda Caps have all the features of the Power Caps plus they have the advantage of a Spark Plug Wire Hold-down.
