Notes: w/ Spark Plug Connector - When Replacing Ignition Coils it is Recommended to Closely Examine Wiring Harnes for Cracked or Broken Wires or Loose Connector Contact Which May Cause a Poor Connection Resulting in Intermitten Misfires. - Failed or Burned Up VW/Audi Coils are Most Commonly Caused By Poor Electrical Connections, Wire Harness Breaks or Fouled Spark Plugs.New Connectors Should be Replaced When replacing Ignition Coils, Especially If There Has Been More Than One Coil Failure. A Loose Connection (Caused by Engine Vibration, a Cracked Connector Housing, Cracked or Broken Wire Insulation) Can Cause a Voltage Spike Which May Not Only Destroy or Burn Up the Ignition Coil, But Also the Neighboring Coil Because the Harness Wires are Bridged Together. The OE Connectors Are Not Designed to be Repeatedly Unplugged and Re-Plugged. VAG Recommends Replacing the Connectors if There is a Chance of a Loose Connection.

Notes: May require 4D0 973 725, 5 Pin Ignition Coil Flat Contact Housing.
