As Arctic states, best concentrate on the water ingress likely due to the sunroof drain tubes having parted where they join hidden just above the front footwell bulkheads.
The rubber item could be anything and as it's quite small unlikely associated with the rainwater drainage system; the network of hard (glossy finish 9mm and 12mm) black plastic breather pipes wend their way around/across mostly the top end of the engine and tend to break/crumble with age hence my first guess. As the plenum chamber is just like a big gully anything small and loose can find it's way into there - the only worry is if it and any other detritis then blocks the drains. Depending on spec./age of car there are 1-2 upper drains - you can fit the end of your little finger into these - located O/S and N/S above both wings near the fire bulkhead venting to the outside hidden above the wheel arch liners (the O/S was dropped from later cars) and another two lower drains in the plenum floor which are bigger (middle finger size) - the N/S is clearly evident but the O/S is almost invisible 'conveniently' located underneath the brake master cylinder - these both vent to the outside around the back end of the front subframe via protruding tubes. If these are blocked then there is a high risk of the water pooling in the plenum and giving the engine control module (ECM) a good soaking - a very expensive pastime; if not checked rising water can then leak into the cabin via the pollen filter housing - another expensive pastime!
