Can anyone help with a suitable part number/dimensions for the smallest K&N Cone filter that will handle the job for a standard NA 1UZFE engine?

The filter area is too small with the BFI, or stock sized filter.
Go with something that has around twice the area and you'll be fine.
Otherwise you'll be limiting yourself when running over 4,000 rpms.
Then, drill a large hole at the top of the front wheel well, run the intake into that with a filter setup and you will get the best flow....Maybe better then the BFI...
