Been using K&N E-3450 for years…recently purchased a Tempest AA10-3450 from ACS. It is supposed to be a direct replacement… But it appears to be substantially smaller, both in height and OD. Now I don’t know if I got a one off, or if they are all like that… Anyone else have any issues with the Tempest size wise?

Aircraft Spruce has two different air filters they claim to fit the Vans planes. One is labeled o320 and one is labeled o360 with a different part number. Maybe you got the "O320"?
