403 air filter
 

Is there a readily available air filer that fits 401 / 403? I used to use Fram CA646-PL which I think was for Morris Marina or Ital but it seems this and its equivalents are no longer easy to find.

Dave,
This might help.

I fitted an Alco MD5140 for a Hatz plant. Readily available on E-bay

Thank you both for this. I think I will go for the Delco unit. Based on nothing more than the pictures I wonder if the punched metal plate in the Alco would be restrictive at higher RPM.

I ordered the filter as suggested by Geoff but was a little disappointed it is a fair bit too short. I finally found a modern equivalent of the Fram CA646Pl from Inline Filters part number FA14881. Around £12.50. inlinefilters.co.uk
See photo for comparison.

Dave,
Sorry about that I was obviously looking for a source of Marina or Ital filters and these were also coming up as an alternative on some listings, also I had been told an A60 filter would fit but obviously from your photo they are not tall enough, I seem to remember one of the filter housings I had did not have a very tall filter in it so perhaps the same. I will ask my pal John who has an A55 Cambridge if he needs a filter and if so to give you a ring, he is a fellow BOC member.

A P.S to this,
I have just looked at my copy of the Fram Master Catalog again, the air filter listed for the Marina and Ital is a CA646, this is also listed for the later A60's from chassis number 50071, however the earlier A60's and A 55 MK2 used a CA641PL so a CA646 may not be suitable for that model.
The link I initially posted was for an equivalent filter to the later type because it was cheaper than some of the ebay options.
My Fram Catalog does not list anything for the 2/2.2 Litre cars but for the 409 & 410 it lists PH8A for Oil & CA160PL for Air. For the 411 PH43 is listed for Oil & CA127 for Air, for the later cars up to the Brigand/Britannia only the Oil filter is listed which remained at a PH43 throughout.

Glad you got sorted. As an alternative for the future, the Unipart equivalent is
GFE 1005 and these still seem to be available, usually at a similar price to the Inline Filters offering.

I've just replaced the air filter on my 403 with a FA 14881. I had to carefully carve some plastic off to get it to fit. The raised lip on one end was far too thick. Works OK with the modification.
