There is a nice short Beru (resistor and non-resistor) connector where the wire is 90 deg that will fit a 12 mm sparkplug. The great part of this is it fits under the lower valve cover!

Once you have a twin plug that is all settled in and you rarely have to change plugs, this is a great solution for a street car. The connectors and wires are all protected by the valve covers. Yes, to change the plugs you have to remove the valve covers. That can be a pain. However with a good running engine it works great. It keeps the wires and connectors out of the debris and water path from the rear tires.

If you want to appear original single plug, this hides the second ignition.

You would not do this for a track only/race car.

Of course if you want to show off your twin plug installation; long connectors, bright retaining clips, and bright red/yellow wires work great.


Let's see your pictures of this plug connector under the valve cover set-up...
