Team.
I have been in touch with K&N and they identify Part number 56-9247 as the
most appropriate for a 3000 with two carbs.

It is a classic pancake filter with a diameter of 6" and a depth of 2". A
bit bigger than the 59-9320 but then we have almost double the displacement
of an MGB. The backing plates are blank and have to be opened up to match
the HD6 or 8 carbs. That gives the opportunity to offset the rear one lower
to clear the shroud.
As for the breather hole, my vote is don't bother. Fit a PCV valve as
detailed in Norman's Tech Talk. A superb and discrete mod that completely
eliminates the oil leaks caused by crankcase pressure. I fitted the air
filters and PCV to my BJ8 and will be doing the same again to my modified
BN4 which will soon be fitted with a slightly breathed on 3000 engine. DWR
cam, gas flowed head, HD8's.

Al,
K&N Part Number is 59-9320. I had bought a couple (from Moss?) some
time ago thinking I would back date the 80 MGB to twin SU carbs. Bought
the third from K&N via ebay for $57. These have a stamped steel
housings. K&N lists this filter for the HIF4 carb and don't have any
listings for the HS4. If anyone near Riverside, CA has these fitted to
a tri-carb, it might be nice to stop by K&N and show them. I'll
probably send them an email/photo.
To Chris' email: I did check with APT about fitting air horns, but they
didn't think there was enough room with the conical filter to be
effective. I remember someone telling me about the Australian aluminum
housings at the car show at Conclave last year. Will have to see if I
can remember who told me.
To those that have send me suggestions for the breather, thanks. Will
let the list know what I end up with.
Cheers,
Bob
