I'm sure toyota designs the filter box to have enough area that even after several 10's of thousands of miles theres still enough unclogged reserve for air to pass by to feed the engine. a/c myth is a good one. don't trust the scan gauge because its just telling you instantaneous results based on sensor feedback. truth comes in final calculation after fill up. I've done highway trips with fill up after both windows down no a/c and windows up full a/c and definitely the mileage winner was windows up by at least 5mpg in a small 4 cyl sedan. and old a/c system will not be as efficient possibly causing more power loss due to it wanting to lock up (lack of lubricating oil) probably someone doing a vacuum job and not refilling
