Excellent Quality product, however in keeping with some other comments it is not a perfect replacement for the standard Ford part as the angle of the bend is not identical which makes the fitting without dismantling the air box problematic.
Very good quality product but I think its dimensions are not a perfect match for the RS,at least the one I got.My impression is it should have a slightly smaller angle and a bit bigger diameter on the air box side.Of course it fits anyway and I am happy with it.
