So which is better? removing intake resonator or drilling airbox?

Just spend your money on a good filter. Spoon uses the stock Honda box in their race cars b/c it gives you much better high rev throttle response. It kinda sucks (or doesn't suck enough as the case may be) at low RPMs, but you can actually feel how much better the engine will behave with all that crap still attached. It has to do with the vacuum that is created in that resonator when your engine gets up to higher revs. The vacuum increases the air speed into the whole system while still maintaining a surplus of air, JIK you mash on the throttle. The Spoon guys have a much more eloquent explanation, but thats basically it. I would have never believed it until I tried it.
