drilling airbox.... pros cons ?

[davidwilkie84]

heard its a lot better than an induction kit, so... how many holes/what size and what part of airbox ? pic of box provided.... guidance appreciated. and would i need to change my filter to a kand n panel or is the original ok ?

it'll make it louder and let warm air form the bay in. dont do it.

replace the filter with a performance panel one and put 70mm ducting from the grille next to the horn.

Will work fine as long as you ONLY drill wing side and front of the box.

[monkeyalan]

if your just after induction noise, go ahead. if you want more performance, drilling your airbox will make no difference whatsoever. if an enclosed  kit like a viper or similar only give a few bhp , a few little holes with no additional airflow to speak of would be worthless.

Drilling the airbox correctly and adding a performance panel filter will add a few extra bhp, so worth it for the money, stock air intakes are deliberately restrictive to reduce noise. However what people generally are unable to grasp is that such a mod will do more for the driveability of the car. Its not the overall gain the counts, its the fact that mid range torque will improve noticeably.

sorry guys i have to disagree here, when i had my congi with a k&n filter and straight through zorst from the cat back the car sounded absolutly mint some people said it sounded like a vr6 but now ive put it back standard with a little hoover size pipe for a forced air into the airbox it sounds quiet as hell but the car goes like fook now!
so id say forget the k&n forget the zorst just keep it standard and just put a pipe from the front of ur car to the air box, also its now doing 100 miles per £20 where before it was only doing 50 miles per £20

Looking at the photos you've obviously done what you described. Has it made any difference ?

[monkeyalan]

 i think so , i did it almost as soon as i got the car so it's hard to remember. i think it seemed to rev more freely and be a little more eager to pull when you floor it. nicer sound when booted but no noise difference under normal driving .nothing massive but worth it for £50 .

where did you get your ducting from ? i have ordered my filter and just need the ducting now.... and where do you have it fed to ? just behind the bumper somewhere ?
