Ok so Heres 'the holesaw job'. for 93Integra and anyone else who may be interested..

Firstly, to make life easier for yourself, remove the right hand inner guard, air box and even intake pipe if you want.
(its only necessary to remove the bottom half of the air box so you can undo the clips holding the 2 halves of the air box together and just hold the top half and intake pipe out of the way while you remove the bottom half)

once the air box is out the way you can begin to remove the resonator much easier if you get the inner guard out of the way.


now to cutting holes. this first one isnt necessary as the factory ducting flows a reasonable amount of air into the box. however if you want to get the most you can leave the factory ducting in place, but cut out a lager hole in the front of the box. now your getting air from the ducting and from around the headlight.


the battery is a good heat shield from the motor, so next we can cut a hole in the side of the box without having to worry about it sucking hot air


your air box should now have three holes in it. 1 in the bottom where the resonator was, 1 in the front and 1 in the side. all thats left to do now is put it back together and enjoy a mild increase in power and economy and an awesome intake note!

NOTE 1: make sure you only cut up the bottom section of the air box. cutting holes in the top half will allow unfiltered air into you engine.

Note 2: whilst this mod lets in more air it also lets in more dirt therefore you may need to clean your filter more regularly. Because if its all clogged up it defeats the purpose of cutting the holes.

Hope this helps. sorry theres no pics of the holes cut in the box or of the resonator removal, it appears all those pics are lost for good. might use my parts teg one day and make a proper DIY on this.
