Hello all, I must first apologise for the lack of knowledge of engines as I have quite literally started today. Anyways, I'm wanting to install a air cone filter on my 998cc mini mayfair (1992) I'm having trouble on how I would install it and any recommendations on which one to buy. Im pointing in the directions of a K&M one.

The pictures below are of my engine currently. The stock air filter is cracked so that's why there is red tape around to keep the housing together. When you remove the air filter housing a hole is revealed at the back of the engine and a pipe leading into the engine is revealed. The pictures below show better than words.


So back to my question where does the airfilter cone go? Do I have to link the two holes to a single pipe with a filter on the end?

Again I'm pretty sure it's daft asking a question like this on here never the less you learn something new every day. I appreciate your patience thanks.

Personally I would not bother fitting a cone filter, they make more noise than the standard one and can make the car run badly. You can get a K&N that fits in the standard housing. If you do fit one then you need to remove the elbow bit with the bolt on it.

Hi, the tube on the left is a warm air feed, it helps the car run smoother when its cold. It only works with the standard air filter housing so if you fit an after market air filter you can remove that.

As for the other part, that is the neck that draws in air to the carb. The silver thing is your carb. Depending on what air filter you buy sometimes you remove the elbow from the back of the carb and sometimes you don't as the new filter will fit over it.

Make sense or still confused?

Another thing to consider is if you fit a performance air filter, you may need to change the needle in the carb.

Thanks gents. That makes sence I didn't know what to do with the tube on the left so I can just remove that. As for fitting the airfilter over the elbow over the carb do I secure it with a jubilee clip of some kind?

Depends what you buy, years ago an old boy gave me a filter which went over the elbow, I don't remember what make it was. I believe with the k and n you have to remove the elbow and the filter screws into the holes, but as I said it depends on what kit you buy.
Whatever you do I'd put the standard air filter housing to one side and keep it as they are getting thin on the ground and its handy if you want to put it back to standard.

I think there could be a spacer to go between the carb and the cone filter, there is a nut to take off to remove the filter part and then you can bolt the back part of the filter to the carb and stick the filter back on and do up the nut. I would keep the standard filter housing, just in case, you will no doubt be able to hear the difference between the 2 sucking in air.

Right will do. Do you have to purchase an airfilter that is particular to your carb or can you buy any filter and plonk it on? And changin of the needle in the carb is that best giving to a trained mechanic or is it worth my time in taking a look and learning how to do it myself? Better worded is it easy to do? Thanks.

[alex-95]

Changing the needle is fairly easy to do, I think it shows it in the haynes manual or have a google search of the su carb., It's setting it up to run correctly that is the hard part if you heven't done it before, If it is running well now I would just leave it alone.

Your best off speaking to someone at like mini spares, that way they can get you the correct filter kit for your car. They are pricy but the filter can be cleaned rather than replaced.

As for the needle, a rolling road session with a mini friendly tuner is the best way. If your after performance then it may be worth you looking at a stage 1 kit.

If I were you I'd give mini spares a ring and speak to their friendly staff, they know their things. Also try searching on the forum as there is plenty of info available on here

Brilliant again thanks gents. Last question and I'll leave you alone. Looking through air filters some say HS6, HS4 ect. Is this different variations of carbs? If so how do I identify mine? Thanks.

[lsto]

I think there is a how do I identify my carb thread in the FAQ section
