Forums » Car Technical » should i get a K&N induction kit?
"as above ive been looking around but heard good and bad feedback about them? so should i bother? what are the gains? and how much horse power will i get as a mate said you get 5HP from adding one?? also apparently K&N only make a filter for a car if it will actually boost its performance?"
"Usually you can buy a universal K&N. They make more money out of you when they said is specifically design for a make of car. 5hp is a bit optimistic more like 1-2hp. Make sure you add a cold air feed too as this is where most people go wrong and loose power. You get a nice induction sound I must add too."
as above ^^ its all in the ducting
always worth looking at companies that specialise in them or car mags to see if they have power graphs to back up there claims. I know the likes of Fast and Performance Ford always do tests on these types of things...
"ive always been told a general cone will just make noise and loose you top speed but improve acceleration. (i found this to be accurate from my bravos also) a enclosed filter holds presures and gives a good overall top speed and accelleration. the BMC CDA is a good example of this however they are expensive! and as above the cold air feed is a important facter also."

"Hmmm good question. I also have a polo (96). I didn't think it would be worth buying one so I made a simple cold air induction kit myself. I replaced the old air pipe with one which runs to the front grill between the lights. (I had to bore a hold to feed the pipe through next to the radiator) Then I removed the old air filter as it's flow rate was shockingly bad. I left the air box empty and added my own fast flow filter inside the pipe made form fast flow foam. (Also this was done for the bleeder pipe) All in all I would say that it has increased my polo's performance slightly. There is a noticeable difference at mid range speed acceleration. (30-60mph) Also I may just be being paranoid but I do think that there is a slight reduction in top speed by about 5mph. So I do think it is worth doing."

"It's the same foam from one of those mushroom filters. But as an update I have scrapped that and I have a ripspeed Cone filter (Mate got it dirt cheep) running straight to the inlet. Mind you I have read an article about Polo's not liking air induction kits and recommend a panel filter."
