    Default Iíve done something wrong here cdti air box conversion



    Every other picture Iíve seen the pipe isnít that close to the air con pipe!

    Donít understand really. Do I have to cut down the red pipe? Or mount the box different? Iím gona have to put my cone filter back on because I donít want the air con pipe rubbing and splitting open

    You might need to push the crossover pipe all the way down to the little nut where a vacuum pipe goes into from front boost solenoid bud

    Actually Iíve seen the extra bit of pipe you have going into the air box try shortening that pipe

    How will I secure the maf inside the air box?

    It is pushed all the way down to the solenoid mate. The ones Iíve seen done before usually have a small bit of pipe between airbox and maf?

    When i got my cdti airbox the maf was to big to fit in so i sanded it down to make it bigger, squeezed the maf in and its been in place ever since, bout 3 years now!

    I'd hazard a guess that direct route pipe is more likely designed to fit onto a cone.

    Be better off buying a full cdti kit with hoses designed for it. I had the original percy one so fitting was spot on.

    Also you've made another mistake and left your oil filler cap off

    Bloody hell. Going to have to fit my cone again which I really donít want to.

    Oil filler cap was off as I was giving it a top up

    You can just see the whole thing is squished down including the left side of the breather pipe bending further down than it should. There's too much mass up top (I.e the airbox).

    I would say you may be able to do some creative trimming of the silicone but where the trimming would most be needed is where the pipe joins the maf and the location of the breather join by the looks of it doesn't give much trimming manoeuvring room.

    Also have you bored out the airbox to 80mm? They come as 70mm diameter and have to be widened to 80mm for the correct airflow. (Many kits you buy come pre modified)

    Reason I ask is looking at that join (maf to airbox) it looks like a reduction in size as it enters the box itself. Which would totally screw up airflow and power.
