An accurate timing light is extremely important to the performance of your engine. MSD's new Self-Powered Timing Light is a tool every performance tuner should have. A great feature of the Self-Powered Timing Light is that it does not require 12 volts. This means less wires are hanging over the engine compartment and makes for quick, easy checks.
