k&n plus drilled air box

[snake16valve]

Hi gambit..i think that my air box is the early one..it has the flap on the box at the wing side.
Is that what u r talking about ?

[Gambit]

if your car is pre Aug 89 then it'll have the earlier box.

[snake16valve]

Yes forgot to mention that my car was an 88 F plate..cheer's..

I have a k+n cone filter...does anyone changed their cone filter for a drilled airbox and performance panel filter?

Is it worth it?

[...joe]

yeah i've had green and k&n induction kits and neither worked as well as the standard airbox with a decent panel filter.

[DavidGTi]

Ah, right. Cool.

My mates got a spare standard airbox, so I'm going to nick it off him!

Where do I need to drill holes? If any at all that is?

Your full of info today mate! Brakes/airboxes 

[...joe]

ha ha yeah i do try....

ONLY drill the wing side of the box and ONLY in the lower half. any holes in the engine side will suck in hot air... not good, any holes in the top half will miss the filter and suck crap into your engine. also when you have the box open, pull out and discard the trumpet type thing like gambit suggested. its only there to keep things quieter but also restricts air flow.
