I tried using cheaper generic 'O' rings and suffered leaking injectors - not good! So I refitted with the genuine Mazda items, purchased from here and have had no problems since. So, recommended! Remember to use a smear of oil to prevent the rings from pinching. Note that I've only rated these 3 stars since however good they may be £2.12 is VERY expensive for an 'O' ring (the generic ones I tried only cost 5p).
