Bosch Spark Plugs for BMW 740iL by Vitznau, September 29, 2014

Ease of Use/Installation:
Overall Rating:

Excellent Quality Sparki Plugs. Previously, someone had installed inferior Quality Spark Plugs in the Vehicle and they affected Performance. Installation needs to be carefully...Engine Cover has to be removed, Electrodes have to be extracted (affixed with Screws), Spark Plugs are set very deep inside of the Engine. There is also a Ground Connector that should be disconnected and reinstalled carefully. Spark Plugs do not need to be gapped. One must take the Time and Patience to put them in correctly or entrust someone who is both knowledgeable a Patient in order to do the Operation. The Spark Plugs are giving an excellent Performance since they have been installed.
