air filters

Post by **briank** » Mon Jan 31, 2005 9:40 pm

hi all I am planing the first servis on my newly aquired 59 2 door. At the moment it has an oil bath type filter, could anyone coment on how efective these filters are. This is the first time I have actualy seen one on a car. should I maby just convert it to a k&n cone filter or some other modern filter your advice would be much apreciated.

Well, they do work but the paper filters are better. It will be fine for that engine, but you could fit a later type paper filter from a later car if you want it to look more original than having a K&N filter on!

If you do decide to get rid of the oil bath filter then don't throw it away as these items are becoming more sought after as more owners want to restore their cars to original condition.

started on the 'let's clean and tidy the engine bay' trip a week ago. our old mog was a paper filter jobby. fifi's ain't...
took it off rather enthusiastically (not realising it was full of oil) and waterproofed myself! i think we shall keep this part on the car - it's an impressively substantial bit of kit!

Remember if you do change to a K&N or similar you will have a lot more induction roar.

Today I read something about carburettor ram pipes for SU's. How do they work and are they any good?
see: www.burlen.co.uk

Yes they do work, but unless you are running a highly tuned engine they are not much use. Certainly not on a standard engine.

all right then, K&N does work on standard engines?

Yes, a K&N is an air filter which provides excellent filtration with hardly any air-flow loss.

BUT obviously they don't look original, oh and they last for 100,000 miles before needing work

Where do I get them, just at my local K&N stockist ( read employer)? any serialnumbers? for the 1098 engine.

hi all thanks for the info. I have no idea on serial no's Onne but I was just planing on asking the local agent for whatever they sugest for newer 1100cc cars on the market then fabricating my own adapter wetween that and the carb. Between my knowlage of composites and aluminium casting it shouldent be to dificult ether which whay I decide to go.thanks again

But surely there should be some readymades one the market as I hear everyone talking about K&N

Just ask for one to fit a 1 1/4" SU carb.

I ordered one today, just by giving the carburettornumber, 65 euro though, that's 42 squid

The downside of fitting a K&N is there's no warm air setting for the winter so the carb might ice up -mine did once, cue a few minutes wait on a narrow country lane until I could restart the engine...
I've now got a Metro filter & carb which has the bi-metal thermo-thingy to suck in warm air from near the exhaust manifold. I've always found the car runs more happily with a warmer inlet, goes quite nicely after sitting in traffic for a few minutes (apart from the over happy chattery fuel pump.

That's very true, Stig. I have never had carb iceing on my car though, I have been using a HIF44 carb with K&N, MG metro inlet (without the water connected) and an LCB exhaust manifold.

The metro filter will improve iceing matters but won't filter or flow as well as a K&N. Mind you, it DOES cut down on induction roar!
