Default Mods For Stock Intake box

Hey there i am looking for some mods that i can do to my stock intake, before buying myself another intake, you see i live in south FL and the weather here sucks. there are times of the year that is really hot, and it rains like crazy too on rainy seasons. i was looking to buy an intake that is good against both heat soak, and hydrolocks, but i got recommended by a fellow s2k owner to just keep the stock intake and mod it. so i am looking for some good intake mods, and THANKS FOR THE HELP

You can gut it.. Remove the divider wall and use a piece of the removed wall and glue it to the hole in the bottom of the box. Google it.i know there are posts on it.i modded mine before i was boosted.

Modifying the OEM box isn't necessarily going to provide benefits, but it defilnitely has trade-offs. For example, if you plug the ~1" hole into the helmholtz chamber, that will reduce torque below 3K RPMs, and increase torque slightly above 3K.

I plugged the chamber because it is the hottest area of the oem air box as it sits installed in the engine bay.

I added a J's Racing kevlar snorkel on the oem intake box, it sucks cooler air and the car feels really consistent throughout the day from morning to night. It might be restricting air flow a bit but the cooler intake temp makes the car drive better IMO. I know the air box is completely dry after driving in some big rain storms at highway speeds, it could be submerged under really deep water though but that would be almost impossible in my parts.

The helmholtz chamber in the air box does not have any air flowing through it, so it will build up heat. However, that heat really doesn't go anywhere. The whole chamber actually provides insulation.

Do you happen to have a dyno plot to back that statement up (in a friendly way)?

Yes, I have dozens of dyno plots showing many different "tweaks" to the OEM intake, but I'll share just this one right now. These 2 graphs are an average of 3 pulls each within 15 minutes of each other (did 3 pulls, inserted a "plug" in the hole, then did 3 more pulls).

I plugged and gutted my airbox. Even took out the elbow. Then added that BPI velocity stack with a K&N Filter. I wonder what the dyno would look like on that.
