Do air flow induction kits for cars really make a difference? Is it worth changing them?

I am due for a service so will be changing my air filter as part of the service. The air filter is the standard audi a3 air filter. Someone suggested getting a K%26amp;N Induction kit or a pipercross induction kit but are they really worth it?





Do they actually make a difference to the cars performance?|||The trouble with induction kits is they are great on the race track but for normal driving they suck hot air from under the bonnet, especially when stuck in traffic.


I had trouble with a bit of pinking with one of my cars, and was told by a tune up engineer that i would be far better of with something like a K%26amp;N replacement panel filter, as it utilizes the cars original induction system which after the millions of pounds of development they have invested would be more than fine.


Unless you do high revving driving all over the place a replacement panel filter will do just the job, you just would not really notice the difference between them. And by the way i have spent more money on this stuff than i care to think of.|||Yes they do. K%26amp;N are very good but you might have to enrich the mixture to get the full benefit|||it will get more air .wich means a better burn .and gives more power.get it chipt up aswell thay will give you more power and a better top end.do both yehaaaaaar|||i had one on my first car (festa 1.25 zetec) which made it quicker off the mark but slower top end. hope this helps|||On its own, it might even cost you some performance. It%26#039;s onlr really worth doing if you fit a performance exhaust, by which I mean a proper sports system, not just a Chav back box, and get the ECU remapped with the car on a rolling road. Doing this might get you another 20-30bhp, with the car still driving properly.|||I personally don%26#039;t think they are worth the extra money you have to spend to get the high flow system as you might gain 5 or 6 horse from it and spend $150 to $200 to get it when you can put the K%26amp;N regular filter in your present airbox and get almost the same increase in horsepower.
