Webasto Photo Disk
Webasto photo disk.
Photo Disks must be straight & clean and "Goldish" in color.
Warping or discoloration is a failure of the photo disk and will result in damaging your electrical harness / electrode wires.
Discoloration in electrodes means the tungston coating is deteriorated, and must be replaced. - Electrodes: WPX-274-313
Photo Disk Clip retains proper location of the photo disk so the photo disk properly seats against the combustion tube
