Product Description:

Rotor for Marelli Distributors with Resistor
911 1965 to 1971
S112AX and S112BX distributors

We have had this produced in original Bakelite and added the resistor to correct the resistance for the ignition system.  The rotor has no resistance and the system requires 5K on the coil side;  this small inline resistor will go on the center post of the cap to coil wire.  It has a screw-on connection to your existing solid core wire.  Correct resistance in the secondary ignition is essential for optimum spark energy.

We have chosen to eliminate the problematic speed limiting function on the original rotor and supply this rotor NON LIMITING.  The rotor comes with the two cheese head screws and washers for installation.

Sold per kit.

Direct replacement & happy that it no longer has the RPM limit cut-out feature. It was a bit tricky to get the silicone/rubberised resistor housing to fit over my 8mm Magnacore coil wire.
