Cain has the iridium plugs for the Sigma engine , my car is now 7years old with 15K miles , I am thinking it is time to have the timing belt changed does anyone have the part number for the belt as I will get my local garage to do it when it is in for MOT .
IIRC, you need a kit - including water pump.
A Caterham based post on Pistonheads quotes: OEM Ford part no: 1780142 for the kit.
In your shoes, I would call someone like Cain or Brands Hatch Morgans to be sure of getting the right parts.
