The Street Fire Capacitve Discharge Ignition is perfect for performance enthusiasts with a tight budget. The ignition offers capacitive discharge technology and will fire a series of multiple sparks that last for 20° of crankshaft rotation when the engine is running at lower rpm. This ensures combustion of the air/fuel mixture and produces great throttle response and smooth idle. _x000D_ _x000D_ The CDI is built around a durable cast aluminum housing and easily connects to points, amplifiers and magnetic pickup distributors. An adjustable rev limiter will protect the engine in the event of driveline failure. This rpm is adjustable with rotary dials in 100 rpm increments. If you have a 4, 6 or 8-cylinder engine, the Street Fire CDI will connect and fire it up! _x000D_ Covered by CARB E.O. # D-40-43 Full featured ignition from MSD that delivers quality at a budget price.
