OEM hoses were a pain in the ass to get on if I remember correctly (and they don't use a clamp) - did you match the ID? - not sure how well silicone hoses stretch to go around a fitting
THe OEM hoses used as samples are the correct part numbers if that's what you mean by matching ID.
A key advantage of silicone hoses is that it's easier to get on and off as compared to rubber hoses. The other advantage, which is more commonly known, is its long term durability under extreme temperature conditions.
ID = Inner Diameter in this case, I think. Maybe I'm wrong but I think what Ant was eluding to is whether or not these would be quite as "snug" and difficult to install/uninstall, as compared to factory.
