Professional Products Powerfire distributors feature an easy installation with no external spark box necessary. The precision CNC-machining and hand-assembled construction includes a patent-pending positive lock manual advance/retard knob.

The Professional Products Powerfire distributors can be accurately advanced or retarded in 1/2 degree increments on the fly by turning the external adjustment knob. Each click of the knob provides a 1/2 degree change to your total ignition timing. This makes getting an accurate setting extremely easy. They use a .500 in. diameter hardened steel shaft with sealed roller bearing upper support and bronze bushed lower support for extreme stability at maximum rpm.

Another feature is a powerful magnetic pickup and CNC-machined reluctor pickup and a fully adjustable advance mechanism with an easy-to-use spring and bushing design for a nearly infinite advance curve. Professional Products Powerfire distributors are finished off with a Powerfire module built in for drop-in reliability from 50 to 10,000 rpm, a black anodized base with laser-etched timing marks for easy visibility, and high-quality injection-molded caps with brass terminals for long life and conductivity.
