drilled airbox slowed mine down after having an induction kit. drilled airbox couldnt take in enough air, was getting black smoke.

so if you change the panel filter on a corsa c sxi to another kind of panel filter it will not alter the sound?????

i prefere panel filters cuz my 1400 16v ad a pipercross and all cone filters r the same i found it was suckin in to much warm air by the engine and caused flat spots i work for vauxhall as a mech so take my advice do an element kn and drill air bvox on wing side

I put a PVD filter panel in and fitted a cold air feed form the front grill and sealed it inside the standard air box.

Should i have drilled the air box aswell who knows ?

The noise was no different but it got rid off the flat spot and pulls slightly quicker.

I've also go the standard back box on the exhaust, maybe thats why it doesn't sound any different ?

if anyones got any suggestions give me a shout.

it's much better at revving etc...

theirs a guide in the tutorials

first i drilled my air box with 12x 1/2cm holes on the box and also cut away the plastic lip that is at the front of the air box.

i then added a panel filter (PVD foam) and refitted the box after re-seting ECU.

My next step was to fill the car will shell optimax ( WHY NOT? :D )

RESULTS:-
Idle seems smoother and power lasts longer. The car keeps pulling for another 500-600 rpm before a gear change is needed!!!

Not bad for £30!!

I've drilled my airbox but it's not making it much louder. I've got a lot of holes on the underside furthest from the engine and basically didn't drill any on the engine side incase i get hot air going up the airbox. Should I just drill the underside of the airbox to buggery for more noise or would this bugger up performance??

not drilled yet lol, cant be arsed, i think ill just replace panel..any gains gambit?

Green + K&N are cotton
PiperX is foam

no difference in performance or sound!

id just go for the cheapest! which is the PVD panel, which is made by PiperX

Ive only heard/seen the PVD one - and as far as I know its really good :D

corsa-sxi, you got your airbox drilled yet?? :P

green cotton panel or k& n panel or pvd panel? what u suggest?

on its own, no

but if you drill the airbox it will make more noise

does the pvd one change sound and performance from the standard???

cheers

Get the PVD one £25 I think it is :D

and sound!!

jus on throttle response

Will changing the standard air filter to a performance one make a noticeable difference?
