Thank you Roger. This answers my question I think, whether I can use the NGK plugs and the new caps together, as long as all plugs are the same and all boots are the same. I understand that the old boots do not work wit the new plugs, but the old plugs work with the new boots. Great to have gotten your and the other comments. Matt

Hi all, Does anyone know whether the new boot (p/n 265249) can be used with the old style NGK spark plug (safe backward compatibility of the boot), or whether one must use the new Rotax spark plugs with the new boot? Thank you for any feedback. Matt CTLS, 912 ULS
