Cam Angle Sensor Disk for Nissan Pulsar GTiR (54mm OD) – Use this disk if you have an EMS and need to run a different CAS. New Series 2 30-6610 and 30-6620 kits include this disk and do not require it to be purchased seperately. If you are buying your EMS second hand (used), or have a Series 1 EMS, you may need to buy this disk if you are having ‘sync’ problems.

This disk is a direct replacement for the factory Crank Angle Sesnor disk, and the center of the disk should look exactly like the stock one in your disctributor. Be sure to match the ‘hubs’ of your CAS disk to ours before ordering.
