First impression:

The K&N 57i filter can only be found at K&N Denmark. They were the only K&N company which listed this part for the 206Gti with dyno sheet report.  If anyone is interested to purchase the K&N filter, you may contact Jan Bolvig at bolvig@knfilter.dk.  Overseas buyers, cost is around DKK1225, you must pay bank and delivery charges on top.  To see the dyno sheet for the 57i induction filter, click HERE.

 

Filter description:

The filter is a mushroom type, made of plastic with the wired oiled cotton mesh. Filter size is around 11-12cm in diameter, 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

1 Danish manual with K&N stickers

 

Power Blanket:

Purchased in a rolled 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.

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 its reused. 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 instruction  manual states to remove the rubber tubing you must take out the RH fog light.  Unscrewed the plastic cover at the RH side and remove the fog by unscrewing the 6mm bolt.  You may completely remove the OE air funnel or leave part of it in to act as a cold air ducting.  You may cut the OE rubber tubing but be careful not to cut anything else off or you will be in trouble.

 

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 is screwed down using the 10mm OE bolt. Make sure securely tightened or it will bang against the car when you’re 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 onto 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:

The power blanket is used to cover up parts of the filter to protect it against the engine heat.  Instruction manual states to turn up around 2cm along the top and bottom and tied down with cable ties. Then position the blanket so that it covers up the area around the metal piping. Secured down with one large cable tie around the metal pipe at the top.  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.

 

Pipercross filter

A member of our club has just had the Pipercross mushroom (corrugated surface) fitted to his 206GTi.  Induction noise is as always noticeable as with all induction filter systems.

The filter installation requires the OE filter box to be completely removed.  The ribbed OE plastic tubing from the engine is used to connect the filter to the car.  A heat shield should be made to keep hot air away from the filter and also some form of cold air ducting to fed the filter.  Overall appearance is a meaty looking filter under the hood which roars out when pushed, just like my 57i.
