LOS ANGELES - MSD Ignition's Street Fire CDI Ignition features capacitive discharge technology, multiple sparks to improve starting and idle, and full power output at high RPM. Ideal for budget-minded enthusiasts, capacitive discharge technology fires a series of multiple sparks that lasts for 20 degrees of crankshaft rotation when the engine is running under 3,000 rpm. This ensures combustion and produces great throttle response and smooth idle. The CDI is built around a durable cast aluminum housing and easily connects to points, amplifiers, and magnetic pickup distributors. There's even an adjustable rev limiter for over-rev protection.
