Issue with hood vents and exposed intake filter

So just wanted everyone to be aware. When cutting the vents or getting hood vents on your V6, please be aware that moisture will still find it's way through the heat blanket under the hood. Even though I left some of it and to me, the Airaid was not entirely exposed, I figured it would be fairly safe. I was WRONG.

The moisture crept through the heat blanket and the intake filter was completely soaked after it rained today. Now I have to dry it and dry the MAF sensor.

Just a warning to others who may look for a similar setup.

It is still a good mod to do. I will just need to find a water resistant material to put under the vent near the intake instead of hoping the heat blanket shields it. Also, the material needs to withstand engine bay heat.

It did initially trigger some nasty idling, the CEL, and the Wrench light. But after drying everything off and letting it run for a bit, the car is happy again.

Did you do the install for the vents? I haven't noticed anyone that has changed hoods completely having this problem.

Airaid offers a plate that covers the intake for hood vents

Where do you see that? I tried searching their site and only found intake kits like mine. Looks like for the 2015s, they come covered -_-

That au01st. I saw Airaid had these too. But I want to try and find a solid cover first before going that route.

Here is a video that someone with a GT shows the same issue under heavy water. It rained about that heavily yesterday.

He screwed up and cut out the whole section. The stock GT hood (which I have) only has a slit cut down the side of that indent.

No i threw it away. You may want to try and call airaid they should have it. All it looked like was a piece of sheet metal the went over the filter and forced water to run off. They also sell waterproof socks for the filter

Do you think I would run into this problem with a OEM GT hood? I will (hopefully) be purchasing one this weekend, but I also have the Airaid CAI. I know there seem to be quite a few uncovered CAI offered for the GT's...

Well I am reordering a new (GT) hood insulation for my car. Because the slits are on the sides of the undervent parts. Not the whole thing being cut out. JLT has a foam insert you can put in above the vent on top of the intake to block water.

There is a guy who made a YouTube video where he hits stock gt hood with a hose for a few minutes, cold air filter was drenched afterwards.

Is that the video above? I think I will definitely order a pair of those JLT plugs, then run my own water test!

Good to know! BTW, do you remember if the price on the JLT website was for the pair of inserts, or do I need to order two?

The $10 price was for 1. But 1 is all you need. You only need it for the intake side.

I thought the guy in the video mentioned something about a possible concern for the fuse box side. But I wouldn't think that would be a problem since it's OEM design.

Did you screw your hood up? I have 2 hood vents and a dual ram air intake on my hood and it absolutely poured the past few days and I have no problems with water getting on my intake.....

The intake filter getting wet isnt as bad as the MAF getting wet, i imagine it comes down to a combination of things. Speaking of which, a Dual ram air intake? Got pics?

By dual ram I meant two ram air inlets that connect under the hood and go to the same outlet under the hood. Not two outlets for like a TT set up lol.

AHH, you've got a blow through MAF ... you could literally inject water INTO your intake (called wet compression actually, check it out) and not have problems, so yours doesnt count lol.
