    hi i have a e46 compact with a k and n filter but no heatshied so i want to put the standard box back on bt modify it by cutting a 3inch hole in it and fitting a intake pipe to it (link below) then to front bumper.

    would this work to get me more cold air and is it a good idea cheers dave

    Doesn't the std air box have a ducting from above the front bumper anyway? (I know the 6cyls do, not sure on the 4s).

    Btw your thread title should include car year & model type too, change it quick before the mods see it .

    Technically theres no reason you couldn't modify your airbox to accept a secondary air feed, as long as its not by-passing the filter etc. I wouldn't modify the stock feed from under the bonnet lip tbh, but nothing stopping you adding a cold air scoop somewhere else, ie under the car or behind another part of the front bumper with access to airflow, and having that air driven to your intake.

    If you do that, and consider putting it down low, keep in mind if you ever drive through a puddle you don't want water getting thrown up the pipe into your intake, so be strategic

    Heat soak is a big issue, a cone filter without one will probably end up less powerful or less efficient if it gets hot. When in doubt, use a performance filter in the standard airbox.

    Yea I certainly wouldn't place any air intake below the bumper!, that would make the perfect water scoope going through puddles!

    i'm sure my 316ti had ducting...

    fitting that cold air feed won't make a blind bit of difference to performance mind, maybe a light placebo effect if your lucky
