Is there distributor rotor and cap that needs to be replaced on RS?

There is no distributor (so, no rotor, no cap) at all on RS. We have an ignition pack (aka Distributorless ignition system) instead. Just change the plugs and wires.

The RS is distributorless.

Nope, its distrubutor less ignition, on top of the manifold you will see a coil pack with the plug wires going into it. Thats the ignition. IIRC ignition timing is handled by the ECU...someone correct me if Im wrong.

Cool. Thats what I figured. Thanks
