not to sure what section to post this under. has anyone drilled their airbox on the v6? i remember having this done long time ago on a corsa sport and it made a very nice noise, just wondering what it would be like on my mv6

I bought one that had holes drilled in the airbox, it sounded great to be honest the only thing was you kept putting your foot down to get the desired noise

sounds like it would be a good idea. maybe do it today, quickly before the missus wantas to go shopping

You have to be careful that you don't allow hot engine bay air into the box, unless you are not concerned with performance

I did the same on a Vectra and briefly on my previous 2.5 Omega.

Well for a week I did anyway.

Got fed up with the cars sounding like a dog. Made them sound like I had a major exhaust problem, it impacted my MPG dramatically PLUS left me feeling like a complete and utter pratt.  Blocked the holes up as soon as I had the chance.

Unless you're a 18yr old chav....I would advise against it.

wouldnt bother if i was you    surely if its noise your after wouldnt it be better to get one of those induction kits

turns out it was already done, the bottom has been done. notced today a bit of hair coming out of my exhaust, baffles are away, and excuse for a new one

Drilling airbox is not as good as fitting a cone filter and cold feed pipe I Know because done same on mine made noise an very little else so went an did cone filter and cold feed. At moment am making powerbox to replace induction set-up.

General understanding is that the area taken up by a clean standard air filter exceeds that of your standard cone.

Why not increase the volume of the cold air supply to create a ram air effect on the standard one?  Less induction noise but, arguably, more HP as restricted by the filter itself?

I have done that.run 5 inch pipe from behind fog light up through to filter.

I'm really not a fan of cone airfilters. Even with a air feed. To open to taking in warm air from under the bonnet. I'd rather a pannel filter or a proper induction kit. Induction kits being rather expensive I plan to fit a pannel filter to standard airbox.

For performance, you will not beat a genuine GM filter, changed regularly.

  Cant understand why someone would want to drill the air box to get an unnatural sound to an omega
