Well its as Serious said he mentioned the oil and cotton make up and yeah ensuring that you replenish the oil on the filter will ensure no dust going in.

Btw. what managment systems would be used on the throttle boddies.. What I mean is what else would be changed to ensure they are efficently used etc...

the ECU would be changed to one that could be mapped specifically for the engine and TBs, something like DTA, motec, omex, emerald etc
you could use the existing EFI system but itd be a proper bodge job as theyre quite limited in the parametres u can put in

Id be far more concerned that the throttle bodies were correctly set up never mind a daft air filter. The standard exhaust on them is good as well - so if it has a stupid noisy big back box, get the standard one back on.

Standard back box on the 106 Rallye is rather nice anyway the noise of it when you drop a cog is immense...

I fitted one on my old mini after I bought it and then got the carb set up properly for economy use, first time I cleaned the thing was five years and 40,000 miles later and it didnt really need it then. Totally out performed the original paper one. TBH a K&N should outlast the lifetime of a car and then some if you look after it.

they sound better with the group n exhaust

Just did a search and found their website, didnt know they had one. TBH it costs less if you have self adjusting fuel injection or some form of automatic tuning as you dont have to  go to the trouble of getting it done properly. Not getting it tuned up may end up with problems.

what with throttle bodies? you have to get it mapped otherwise you can end up with pinking

Never mind pinking - it will have massive flat spots and the mixture will be up the chuff if it hasnt been set up correctly - potential overheating !
