CFM box filter size?

straight from CFM bro.. (copy/paste)

The CFM Performance Blaster airbox uses a clamp on filter with a 2 1/2" I.D. UNI filter part number is UP-6245ST, available from any UNI dealer or directly from CFM Performance for only $24.95. If you prefer a K&N filter the part number is RD0720, also available from any K&N dealer

A bit OT, but this is the off-topic forum.....:D I just ordered a big boxload of stuff from those guys for my turbo 16v jetta I'm building. Very easy to deal with and quick shipping.
