For the LH side remove the screen washer bottle (two screws and two hoses). For the RH side remove the air inlet ducting (two screws on the radiator crossmember, a bolt and a nut secure the rest of the ducting). Remove the plug leads by pulling on the lugs, not the cable. The plugs are best removed using a 3/8" drive 5/8" (16mm) spark plug socket on a 6" (150mm) extension, and a ratchet.
