    I've been trying to put together my own set up for a modified air filter/induction on the 1.3. Its took a while look for what I wanted but finally things came together. Its no perfect/ideal for what I was trying to achieve and still need to do some tweaks and refinements. No stickers were hurt in the making of this kit. Turbo owners look away now :D

    I'll give some more information and details in a later post or if anyone specifically asks something they'd like to know.

    That's because its clean lol, for now!

    The black silicon 90º reducer is a 70 mm to 57 mm (id)
    The aluminium piping is 70 mm. So filter housing is 70 mm id in and out.
    90-70 mm s/s jubilee clip.
    One Wilko's aluminium coat hook (highly modified). I estimate this alone adds 2-3 hp at peak rpm. Thanks to metal man for his advice on this intricate and critical piece.

    I tried to go for a smooth air flow route to reduce turbulence inside. The filter housing helps with this, hence why it was a good find for what I was trying to achieve.

    Also all/most others were 76 mm/3 inch and I didn't want to go to big so I could maintain air velocity. With the rest of the inlet system about 54 mm or less I didn't feel I would lose anything by having a 70 mm system and not 76 mm. After all its only a 1.3 and only goes to 6000 rpm which I won't be at very often.

    Metal man, who's he?:D
    You're all putting me to shame, I've done nothing to my car. Bought a Clifford alarm with an extra button on the remote which I intended to wire into the roof circuit,so I could open the roof from outside the car. To my embarrassment the alarm sits on a shelf in the garage, I must remember to dust it.:D

    How does the exhaust note sound with that setup Trusty? You'll have to tell us how it affects performance.
    I know you were a bit miffed when I called you TAF, hope Trusty is ok.:)

    That's ok DoG. :)

    Not much actually. I can hear a bit of a boom/hum as I'm upping the revs in 5th, i.e. cruising around 4000 rpm. All the other noises like tyres and cockpit squeaks mask it. Cruising at 3000 rpm (~60 mph) I can't hear anything that I attribute to be more than what it was. yeah there probably is some more at 5000, 6000 rpm but I did have my foot down and since I don't do that engine much its difficult to recall what it was like. Even so, if it is louder its no deafening/irritating/annoying and if you are thrashing to that sort of engine speed you either want the thrill of the noise or its going to be brief.

    Its hard to assess performance difference but does feel a bit more racey. I maybe just have driven harder to make it seem quicker. From an air filter mod you never going to get much more performance. yeah I think its a bit more responsive.

    How much was the cost? I know those Wilkos coat hook brackets cost 59p, but how much was the rest?:D
    You missed a chance with your DoG joke. DAG is my initials and I use it on a few different forums. An Australian pointed out to me that a Dag is something that hangs from a sheep's bottom and is used as an Aussie insult. I already knew that because to my shame I watch home and away.:eek: The Australians on here are obviously much too polite to point the dag thing out.:D

    about £50 the filter, £13 the silicone adaptor, £2 the jubilee clip. priceless the labour!

    today did further modification to the adapter to hold the temperature probe. Held it together and sealed it shrink wrap. Then added some insulation tape just to be sure, not shown in the photo. Hopefully the probe is enough in the air flow as the original install the end was inside the adapter. Even thought the car drove ok.
