If you want to have a bit more air going into the stock box, do what I do,
I have a 3 inch hose running from the right side grill area back into the stock box
I also carry a " plug " to install in case I want to cover it to go into deeper water
Have that setup on both the 03 and 04
Been running it on the 04 for 15 years or so

I had a custom snorkel fab'd for my '05 CRD out of 3" alum tube, etc, here in Baja (pics on Lostj____ thread).

My motive was also to install a 2nd battery in place of the stock airbox. Done; now i have 2k CCA's which comes in extremely handy for engine-off accessory use & cold-starts (below 20f).

Am I happy with it? Sure. However, at about $300 Labor & & $175 Parts (incl. K&N cone filter) it was about 80% less to have the setup fabricated in MX vs stateside, an important consideration. I recall that the prefab'd black plastic KJ snorkel kits are what, $750?

Performance? Having an intake at the roofline does enable higher-water fording. But it also helps put your air-intake above both heated air radiating off of the asphalt in warm-climes as well as concentrated dust native to dry gravel/dirt roads. While the washable K&N filters are convenient they aren't very good at actual air filtration. I'm mulling mods to replace it.

While the snorkel setup certainly doesn't rob power I can't declare with technical certainty that it adds any. Maybe.

Just goes from edge of the grill almost straight back to the air intake piece that goes into the airbox
Just cut a round hole in it .
When you rev it up you can feel it sucking air into the tube so I know it works, plus being where it is, force fed at highway speeds as well

Aren’t you worried about taking in dust and other contaminants that may plug your air filter? I am thinking about places like Utah that have a dryer climate

No not one bit, all the states I drive in, not that dusty , well lots of dirt roads around here but I never follow anyone that close
,plus that is why they sell air filters every day of the week
