Pickup coils monitor the rotation of the distributor and trigger the ignition system at the optimal moment to produce the best-timed spark for best engine performance. If you are experiencing little to no engine spark, rough idle, engine stall, or failure to accelerate, it could be time for a new one. Pick-up coils from Wild Boar are designed to OEM standards and will get your ATV running in peak condition without paying through the nose on a completely new OE ignition.
