Heard a couple of people talk about drilled airboxes... What are these? How do you do it and why do some say they are better than induction kits?

Drilled Airboxes?
- Thread starter EssexIbiza1985
- Start date
A drilled airbox is usually mated with a perfomance panel filter.
It basically involves completely removing the airbox and drilling holes on the pre-filtered side of the box to aid airflow - usually the bottom of the airbox, and then refitting the airbox.
These holes are only worth putting in a place where they cannot suck up hot engine air, on my old Ibiza GTi I drilled the holes (10mm diameter) so that they faced the front of the car and the inner wing, no holes facing the engine. The benefits are slightly more induction noise and supposedly better air flow.

untested myself for flow but on part throttle its just like a standard car but on full you get the sounds/effect of the induction kit that most look for
plus benefits of being able to use a std or replacement panel filter as most ind kits are ok but are high maintenance - leave an ind kit to go dry/open for a year and you wont believe the damage it will cause

on that note. iv got a pipercross induction kit on at mo. How often do u av to spray ur foam filter?

washed mines in the washing machine every 3 months or so and re-oiled afterwards.
drilling ur airbox will surely mess up the air/fuel ratio on cars and thus making them run leaner.
to check if ur car is running lean check ur spark plugs,
if they are nearly white - too lean
if they are nearly black - too rich
if they are nearly brown - should be ok

just allows more airflow to be available when required - air flow/density is measured after the filter still even seat designed an extra tank for the higher flow down by the chassis leg
depends how mad you go with the drill bit though i suppose
Umm when you say re-oil what do you do? And what do you use? I dont think ive ever done that to mine.
it wont run too lean as its before the sensor.. an airleak after the sensor would cause issues. it will just keep riching up the mixture until it can no more and light up the dash as the emissions go out the window
u can get pipercross induction kit dirt retention oil sprays. get em in most mod shops and also on net and halfrauds. got sum on friday from halfrauds for 8 quid but that was cos the box was suspiciously damaged ;-)
i've bought a Powertec Induction kit, it's stainless kit, meant to sound amazing, i think with the induction kit it's best to have a cold air feed
Got a Green induction kit on the way. Is it worth replacing the panel filter too? (Well, it's a large ring really)
