Advan-Tech 3F9W Ignition Coil

Product ID: B07L9VRDWK Condition: New

Sold Out

Product Description

Coils produce high voltage necessary to ignite air/fuel mixture in the combustion chamber
When not replaced, vehicle could experience any of the following: no/hard start, long crank time, misfire, lack of power, inconsistent transmission shift points, spark plug fouling, catalytic converter failure, poor fuel economy, CEL/MIL illumination
Designed to operate dependably and reliably under all operating conditions and throughout the entire engine speed range for peak engine performance
Global coverage for import and/or domestic applications

The ignition coil is a transformer which converts the vehicles battery voltage into the required high voltage needed to create an electrical spark across the gap in the spark plug. The spark is used to ignite the air fuel mixture within the combustion chamber of the engine. An ignition coil consists of a laminated iron core with two coils (windings) of copper wire surrounding the iron core. The two windings are the primary and secondary. The primary winding consists of several turns of heavy copper wire. The secondary winding consists of thousands of turns of smaller copper wire. The two windings are isolated from each other.
