cover in masking tap and draw on what you want to cut out
i used a jigsaw (on a slow setting) to cut out the main body of the piece to be removed
then used dremel to remove off further grp to the line markings

1mm cutting disc or a couple of drill holes then by hand with a hacksaw blade.
file to finish

I made a card template and then copied it across to the bonet.
measure more than twice and cut once.

Are you worried about HOW to cut the hole, or WHERE it should go?
If the question is 'Where?' then I'd cut out a cardboard template and hack that around (if you cut off too much, you can always glue
a bit back on). When you've finished, stick it to your bonnet and cut.

Recently did similar for vents in my MK bonnet.
Cut out ideas in card to see that it looks OK.
Masking tape to cover the outline then detail lines onto the tape.
Drill holes just inside the line.
Join-the dots with Dremel side-cutting drill. Great care needed, but can be quite accurate.
Straighten up edges off with Dremel emery tube thingy.
Get a finer finish with fine sandpaper and wood blocks (flat & round)

Cheers guys.
My plan was to.....
Fit air box and rest bonnet over.
Drill small holes from above, working outwards to just within required area.
Join holes with hand held hacksaw blade saw.
Finsh with emery block.
Sound ok?
Its quite tricky to work out the area required

Mount a laser from the roof/ceiling and line it up with a corner of the airbox then fit the bonnet mark the bonnet then do the same for the other
corners, this will give you a starting point to work from and providing you dont move the car in between they should line up. Does that make any
sense.

I think having a few beer prior to starting is not a good idea. Although if I keep going on my car much longer, I'm going to start drinking
again.

I used masking tape to draw the shape i wanted. Then used Rotozip (dremel type thing) with new bit to make the cuts. Cut it freehand then cleaned the
cut edges with emery tape. Very scary job at first but take your time and good result will be obtained. Cover yourself up with appropriate PPE - the
dust gets everywhere and is very irritating.

Not done it yet due to a few reasons.
(1) Its a very rare Westfield narrow body bonnet
(2) I already have a hole where the twin 40's used to stick out... weakening the bonnet?
(3) cluck, cluck.. im a chicken
