    Default air box "lid" modification

    guy's

    here's one for you ......

    just fitted my K&n filter already completed the nexessary bottom box mod a few months ago and i can say - vehicle is much smoother with the K&n straight away- moreso than the basic mod but my question to you is this
    on the "lid" of the airbox inside is a trumpet type section, which would direct the air flow into the chamber, has anyone broken out the junior hacksaw and cut this piece back to allow a more "indirect" flow of air into the box and if so what was the benefit/downside

    if anyone has already doen this mod i would be happy to hear of your experiences as i'm sure so would others and if anyone has a spare lid that they are willing to "donate" for the purposes of scientific study

    then lets get cracking ....over to you !

    I changed the filter with a standard one and did the bottom box removing the plastic tubing and I don't think it made a difference.

    what you have described is the intake trumpet.. that smooths the path of the airflow over the AFM, and is best left in place, there are a few threads on here where members have removed it..

    yeah, as pete said this trumpet is to prevent swirling of air and to direct air through the air mass meter correctly. I wouldn't risk removing it

    Actually the trumpet is to reduce the inlet co-efficient and hence allow air to enter the piping more smoothly and with less resistance than a simple open pipe end

    I didn't remove the trumpet, but have cut the pipe to increase inlet area. Before I did this, the filter only got dirty on about half of it, now it gets a more even coverage - meaning all the filter area is being used for air flow, instead of only half of it.

    One day I'll post a picture of what I have done...
