Depending on the engine it can give you flatspots! i put an induction kit on my car, was a universal one and it gave me loads of flat spots and was real shit at starts.

Depending on what you're after from an aftermarket filter, induction kits will increase induction sound, so may be too loud for some people.
Cheap filters may let crap into your engine, so check that the filter is reputable and has been oiled and fitted correctly.

LET ME HELP YA..
If you are talking about a K&N aftermarket cold air intake (shrt ram), you will not get any disadventage, you will gain more HP, you will burn less gas , you will get more torque and you will not need to buy any filter at all in the whole life of the car..
Oh I forgot, you will get a better sound in your corsa..
I have my self this unit and works very good.
I hope this helps to you.

However, being a cotton-gauze filter, it will have a third of the dust capacity of foam filters and quite likely to have less capacity than PAPER filters!
So your expensive intake system becomes even more costly with a specialist cleaning kit...
Then you have to oil the filter exactly otherwise it either won't filter the air correctly or will be over-oiled which often get sucked off the filter and down the engine's intake system, liberally coating each sensor in it's path.

They are loud and make you look like a chav. Most of them don't filter out as much crap as the sponge filter that came as standard in your car. I said most, not all, btw Joff. Oh and the bit of ducting that comes in the kit.... Wow, that bits usefull.

It shouldn't really, should it.
Taken from the Green panel filter cleaning leaflet...
"clean your air filter between 7000 kms or 1000kms or every 6 months"
Maybe it's just me, but doesn't a paper filter have better service intervals?

All i know is for 1.2 8v Engines they make next to no noise and give a poor bottom end flatspot. where as an induction kit fitted to my Bros Rover 214SI sounds Great and reallty does make a difference in pickup.

erm... taken from the leaflet that came with my k&n panel filter....
"this filter does not need to be renewed/cleaned for 50k miles" (probably not written exactly like that )....

K&N's construction is more advanced than Green's and possibly features an increased number / deeper pleats to allow for greater capacity.
If K&N are quoting 30,000-50,000 miles... then a foam filter in the same environment could be run for 90,000-150,000 miles without cleaning!!

No strain at all, your engine will get more air and will be able to perform with improved efficiency.
The car will rev easier as the air has to take a less restrictive route into your inlet manifold.
You might get a couple of bhp increase by fitting the filter, normally due to the previous filter being old and crap.

Even universal filters will let air into your engine - there's no real mystery inside the cone that creates or banishes flat spots - a lot of it is down to the engine itself, the weather, etc.
To be honest, a universal filter may let MORE air into your engine than a K&N, Pipercross... but only because they sacrifice filtration If you want the BEST airflow, then just remove your airbox and fit a cold airfeed directly to your intake pipe.
Obviously this is bad because you won't have a filter to stop crap getting to your engine...
