Budget-Friendly Capacitive Discharge Technology

Street Fire CDI Ignition is perfect for budget-minded enthusiasts. It utilizes capacitive discharge and fires a series of multiple sparks that lasts for 20° of crankshaft rotation when the engine is running below 3,000 RPM. This ensures combustion with great throttle response and smooth idle. Street Fire has a cast aluminum housing; features an adjustable rev limiter for overrev protection; and connects easily to points, amplifiers, or magnetic pickup distributors.
