Searched everywhere for the 57i filter and could
only find it at K&N Denmark. They where the only K&N company
which listed this part for the 206Gti with dyno sheet report. I
emailed K&N, UK and they haven't even heard of it! I would
trust Demark more than any of the other so called companies which
have the 57i for the 206gti. I did see another company selling a 57i
kit for the 206gti but when I checked their K&N item code against
the K&N catalog, it was listed for the 205 and 306gti. So who do
you believe in the end??? If anyone is going to purchase the K&N
filter, I brought mine off a Jan Bolvig at email@example.com. For
overseas buyers, he offered to pay half the bank charges at DKK30. I
just paid him full amount of DKK60 on top of the filter, power
blanket and delivery charges. Total of DKK1735, delivered within a
week! Very nice service and the filter was nicely packed with foam
The filter is a mushroom type, made of mostly
plastic with the oiled cotton mesh. Filter size is bigger than I
thought from the web site, diameter of around 11-12cm, length of
around 15cm. The insert is angled so that the when the filter is
fitted, it angles towards the front wheel.
The filter comes with the following parts:
1 pcs of metal piping with mounting frame attached.
1 pcs of flexible rubber tubing
3 pcs of o-rings (correct name?)
1 Danish manual with K&N stickers
Came in a rolled large sheet around 60cm x 50cm with
around 30pcs of cable ties. Also came with the Danish instruction
manual, which was kindly translated by Mogens (many thanks!).
Tools needed off the top of my head:
10mm and 6mm spanner
Razor blade if you want to cut the oe rubber tubing
Scissors to cut off the ends of the cable ties
Screw driver for the o-rings
Installation, removal of oe parts.
What I didn't know before was that the filter is
mounted at the bottom of the engine instead of at the top. First
you must remove the pipe attached to the filter housing. Then remove
the cover of the oe housing and remove the filter which is a paper
pleat with a foam backing at the bottom. Looks very restrictive to
me when compared to K&N drop in filters. Once removed, you may
take out the whole filter housing which is just held on at the side
and sits on the pipe below. There is a small clip on the metal
bracket which holds some wires, unclip this and reposition the wires
on the clutch cable. Now remove the 10mm bolt at the RH side and
keep it safe as it's used. The whole metal housing may now be
removed. Now remove the rubber tubing at the bottom of the metal
bracket by taking off the rubber ring first. Then slide the rubber
tubing out towards the LD side. The next part I found very tricky,
the instruction manual says to remove the rubber tubing you must take
out the RH fog light. I unscrewed the plastic cover at the RH side
and got the fog half way out by unscrewing the 6mm bolt. The fog
light didnt want to come out so I left it half hanging. I then
tried to remove the rubber tubing by pushing, pulling, tugging and
jerking at it. The rubber tubing refused to move so with no lunch or
dinner in sight for the whole day (its around 8pm) I got nasty.
I took out a very sharp razor blade and cut through the rubber
tubing. You must be careful not to cut anything other than the
tubing like wires and so. I got a shock at first when I felt a wire
which turned out to be the rubber wire inside the rubber tubing if
you know what I mean? I left some of the oe tubing so that it could
funnel some more cold air to the filter.
Installation of 57i kit.
Now that the oe parts have been removed, install the
filter and tighten the o-ring with it facing towards the front wheel.
Then the metal brackets legs go into the oe position and its
screwed down using the 10mm oe bolt. Make sure its nice and
tight or it will bang against the car when youre driving. Now
attached one end of the rubber tubing to the metal part and do not
screw down yet. Get the other end of the tubing on to the engine and
screw down. Then adjust the piping so that there is a 10mm space
between the tubing and the radiator pipe. Then you may screw down
the rubber tubing at the metal pipe. Make sure the both ends of the
rubber tubing are secured and close bonnet to check for clearance.
Installation of Power Blanket:
I cut around half of the shiny silver blanket and
turned up around 2cm along the top and bottom and tied down with
cable ties. Then I just positioned the blanket so that it covered up
the area around the metal piping. I secured it down with one large
cable tie around the metal pipe at the top. This was only a quick
job as it was raining and I wanted it to be finished. I will most
likely reposition the blanket and tie it properly near the filter and
around the piping. The blanket should not touch the filter,
clearance of around 2 away. Remember the blanket conducts
electricity so be careful not to let any live wires touch it. After
the above you may close up the bonnet and fire her up! Go for a test
drive and listen to that monster induction noise at high revs.
Test report so far:
Driving the car at normally at low revs without any
hard driving, sounds very normal. But when you floor the car, the
induction noise is pretty loud at 5-6,000rpm! The sound reminds me
of wrx style exhaust that make the same kinda noise. The
car feels much smoother and free with the filter added on. I cant
tell of any noticeable performance gains but the car does feel
smoother. I will test the filter with the Gtechpro later and find
out the truth. I do worry that the filter could suck in excess
amounts of water from the low position of the filter. Its
about 9 off the ground so it should be okay unless I ram into a
big water puddle. This would cause the filter to suck in water that
the pistons could not compress and finally blowing up my engine! I
dont think that the suction power from the filter which has a
3 piping could suck up that much water. I dont really
want to know so I will stay away from big puddles! One thing about
the filter, when I rev it quick, it gasp for its
first spilt second of air. I am not sure why this is so, could it be
that the piping is too long and that the air doesnt reach the
engine quick enough? I am open to suggestion, I will get this
checked out later. Fuel consumption looks the same, will update
Thats all for now, will keep you updated with
any further developments. Would I buy the 57i induction kit again?
Of course I would, for the money, its a cheap and effective way
to boost up power even though if its very minor. The filter
sure does look good under the bonnet!

Further Update: K&N have answered a few questions Jim had, so I'll add them here.
Question - I noticed that the filter is at the bottom of the
car, will the filter suck
it water? If so, will this not damage my engine?
Answer - No, it will not suck water into your engine,
if you are driving on
normal road. Only if you drive in high water like sea
or river it will take in
Question: The dyno sheet for the 57in on the 206gti. Did the
car only have the 57i
filter fitted with no other modifications?
Answer - No, no other modifications was made..
Is it working to your satisfation, normal you can fell
the power from 3500 -
4000 rpm and the sound if lovely.
