Well pretty much. And as for water getting in there, ya it can still happen just not quite as easy. The Stock air box setup is better if your worried about water because it would go in the air box and out the drain holes if you don't plug them all. And the inside the cowl version will be louder as well.

Well that spectre one up there is an outside the cowl, you can see where the filter goes where it bows out a little bit. And yeah same here. I have mine to the airbox and I don't hear anything

It's sitting inside the cowl, you can kinda see the clamp for it through the hole in the firewall. I screwed up where i cut the hole, it's too far to the right so when i turned the wipers on they shoved the filter back, causing the flex tube to get punctured on the sharp edges i left. So i have to replace the flex tube now and find a way to grind the edges down and cover them.
@Grandlich, they won't get water in them from normal rain or whatever, the drains for the cowl are efficient enough to drain all the water before that happens... If they are not clogged. Also this is why you DO NOT want the filter directly below the cowl opening, not that it's even possible to have it there.

Okay question. Arnt these spectre intakes and that other brand one the same thing i mentioned earlier doing with the intake inside the cowl. You would run the 3inch tubing from the inside of the cowl connected to the intake??
-cant water still get in this way?
-the passenger side is not dirrectly open above it has some covdr and is more open on the driver side(for air)
Sorry if im being confusing.

It's been raining like Hell and I haven't had an issue with water either at start up in the morning after full nights of hard rain (caused flooding after two days. I was driving past cars with water up to their seats... Talk about pissed off motorists. Emergency teams were there. Made it through 5 minutes before they closed the road) or driving in pouring rain. It is important to cut the hole above the floor of the cowl though so that there is a lip underneath. If you cut even with the floor you may have an issue as gravity will take its toll and all that water will flow towards your valves.

One thing to think about: if you want a cowl intake and you have some fab skill, look around for a canister filter that can be enclosed. Then u can make one like spectre for much cheaper. I was too lazy but I'm sure if someone finds a suitable filter it would catch on. The room that's freed up by getting rid of the airbox is amazing. I put in an air horn and will be doing dual batteries shortly. Prob still have a bit of room left over.

Honestly i see no point, if they both go into the Cowl. Unless you modify the cowl grille, the system will draw the same amount of air since the mesh over the grille opening limits the airflow.
