Late Design This rotor is the later-design version for this application. We no longer supply the early-design rotor and instead recommends installing both this rotor (or Bosch equivalent) AND cap #30102-PM5-305/DAI (or Bosch equivalent) or cap/rotor kit #30102-PM7-305/OES, especially if unsure whether or not the vehicle is still equipped with the early-design cap and rotor.
