Alternative airfilter

Post by **honda90** » Mon May 07, 2007 11:47 pm

Has anyone fitted a different type of airfilter for a hif 44 carb fitted to a 1275 engine, at the moment I have a K&N type fitted but the din from the carb is terrible, so I wondered if there was a silencer type which would fit. Have one from a MG metro but is to big and hits the bulkhead.

Ian (wanderinstar) uses one from I think a Princess - no doubt he will be along shortly to tell you himself!

I have recently fitted a quieter option to my motor. The air filter housing comes from a Morris 1800. It is internally baffled and is as quiet as a std Minor one. It breathes a lot better too. There is a K+N element, E-3260, that fits in this housing. It is close to the shock but doesn't hit. I included a photo of the setup it replaced that also breathed well but was a bit noisier.

I'll keep a lookout for and casing off morris 1800, my carb is a hif44 which looks a bit wider than yours so its possible it could catch the shock if its too close.

If you can find the elbow off a marina/ital you can bolt the minor housing straight on!

will the mini air box fit round it? then you can use a K&N element in the box for best compromise of flow and low noise (so I have been told and will be trying soon)

You any idea what one looks like?

I found a couple of random SU elbows when shifting some of my clutter around, and now I come to think about it I've no idea where it came from!

If you look at the third photo in my earlier post the aluminium elbow is a Marina one. The black plastic bit came from, I think, a Pugeot 206.
The clearance between the shock and housing is about a finger thickness with a 1½" carb and Minispares water heated manifold. There is a thinner carb to manifold spacer available that would give some more clearance too.
Another point is that the housing came off a car with a 1¾" carb so you will not have to adapt it to fit as I did.
