why? heating elements that require a certain air flow need the air to carry away heat, otherwise they overheat. it's like if you cover the inlet on a hair dryer... the element turns bright red and will eventually burn out from overheating. how much shorter? it depends on a lot.
an example from mcmaster: "The fins provide a large surface area for excellent heat dissipation in forced-air heating equipment."
there are some other finned elements that don't say anything about air flow, so you could be fine. dunno. i only know enough about them to be cautious about how to use them. maybe track down technical manual from the manufaturer using the part model number. better to be prepared and maybe have a contingency plan if that one goes out than stranded without an oven if your customer needs a part.
