Review on Delphi GN10328 Ignition Coil by Kevin Johnson

BMW consultant recommended Delphi to Bosch due to potential sealing issues. The spools come in a regular box with a picture but rest assured the spool inside is correct. Each coil is a sealed plastic bag with bubble wrap. Looks higher quality than OEM Bosch, fits well and most importantly it works well. PS Bosch has added an extra layer of rubber around the bobbin so they fit perfectly on the tubes on my N52 motor. The Delphis don't, so if you press the top of the coils when they're in, the Delphis will appear springier and wobbly, but not by too much. Logic might suggest that this allows the rubber contacts on the connectors to flex in use or removal as one can have a slight angle to your movement, whereas Bosch because they are so tight only allows you to rotate 90 degrees. high. Just a thought for no reason.
