With a SEFI car (meaning your ignition is triggered from your crank timing gear) you do not want vibration/misfire conditions. Piggyback pulleys can in some cars can trigger misfires, a top notch UDP incorporates the damper and pulley together, eliminating the risk. Steeda UDP's are certified for SEFI use by CARB (California Air Resource Board). They are good POO-POO!
