Hi there!
Everyone told me that the air filter cone type is not recommended for a standard engine.
So that I would like to know why!
I've fitted it and I found that the engine is much livelier!

You're cone filter doesn't dampen Induction roar like a stanmdard filter in a case, and so..is simply louder hence the 'sounding more lively'
Fitting a Cone filter has now Weakened your fuel mixture ( it is running leaner) and so you will now need to get a New Needle in the carb to compensate and richen the the fuel mixture up,.. this way you'll find a slight performance difference too rather than just a loss.
In my experince (and Keith Calvers, and David Vizards) They found much better performance gains by using a K&N standard replacement filter in a drilled Airbox, comapared to a Cone filter.... Cone filters look pretty, but don't flow as well unless you run aluminium ducting from the grill to the outside of the cone.

but if you get a cheap new 2nd hand K&N whos the wiser.
but yeah sticking a new filter on leans the mix so you have to rich it and/or get a new needle. i personal just changed the mix and went about my day. does sound ... ... better. but i did a drilled air box before so its only a little lounder. i just got annoyed at taking the airbox out and mine leaked. looked for a new box and found a proper K&N for £30. bought that insted.

You should also get your Mini set up on a rolling road when fitting a K&N cone type filter too, but I just fitted a new needle and haven't bothered yet. And yes they do sound good, but can be a bit noisy on the motorway unless you have the sound deadening material fitted.

really my motorway journy home from the tune up after fitting my stage 1 was quite plesant, just dont keep ur foot flat, if u stick at a speed and revs ur fine

will say this about the cone filter. they make messing with the carb internals a bit of a pain. they have a screw head on the back that hits the bottom lip of the dashpot. thats a little annoying. and the corce gasget squishes out....well it dose if you've done it up tight lie mine.

I have had both on mine heres my 2 cents on the topic...
Cone filter
+
Look great
Easy access to adjust the carb
lots of noise
_
hard to optimise mixture
only tiny power gain (although a gain is a gain)
lots of noise!!
Filter element
+
easier to tune
less noise
better power gains
-
harder to access carb (idle adjustment etc)
don't kook as good
less noise!
I personally prefer the filter element but each to there own!

having done a few head gasked changes i had a large stash of paper gaskets that i used to space my filter element out so it didnt catch the dash pot! just a suggestion!
