Installing weather seal on engine bay to protect CAI

[87and66]

Hmm. I have a 2019 GT with AEM intake and it's been raining here all week. And I just came back from driving in the rain. I just ran out and check and I don't see any rain getting to the intakes or even close to the strut bars. Looks nothing like your pic. Then again my car sits in a garage when not driven. So maybe that's why?

i have the exact same experience. I've checked after driving in heavy rain. AEM intakes. no water around

do you guys who are getting water inside not have weather stripping on the underside of the hood? I know the front doesn't have any, but the sides should (mine does) and it seems to be sufficient. They should seal off the gaps on the sides of the hood

There isn't much of a seal on that gap. I wonder if that creates hood lift. Not good for those with carbon fiber hoods lol.

no seal on my hood except for one on the front of the engine lid, about 2.5-3ft long. My engine has been spotless since I put additional stripping on to remove all elements from hitting my engine bay.

My engine has been spotless

Exactly!
And in respect to any heat issues: I just completed a 1,048 km run from Atlanta to Plantation FL in exactly 9 hours, incl. 3 gas-ups and a car wash... so yes, I wasn't dawdling LOL.
Absolutely no heat issues. Yes, the weather was shitty further north, driving through 3 hrs. of rain, but we made up for lost time further south.

always filthy

True!

I would like to note that Toyota offers CAI kits on some models. The fine print specifically says that if you take your car through an automatic car wash with the CAI installed, your warranty is voided. I wonder if they have water markers?

So I’m emptying my catch can today and I look at the hood and realize I had it backwards in my head. You’re right. There is a section of weather stripping on the front and none on the sides. So I look closely at my AEM heat shields and see water spots. Never noticed before. May have happened from pressure washing the car a couple days ago. Never noticed water getting in after rain. But now it’s got me thinking about doing something about it. Hmmm

After driving in recent very heavy Sydney rain I checked and not a issue. Never noticed anything before either.

anybody getting any water coming from under the fake hood vents on the hood liner? i'm seeing quite bit of white residue on the hood liner under one of the fake hood vents and some research I've done suggests that if water sips through and onto the fire retardant hood liner that it can turn into this white powder residue ... anyone else seen this?

does this not restrict intake?

Mine are Filterwears, this is what they say in their FAQ section:
Installing a FILTERWEARS will not result any airflow or horsepower loss. Our pre-filters are made from a polyester mesh specifically designed for filtration. Our pre-filters will actually help maintain your vehicle’s horsepower and airflow levels by protecting the integrity of the air filter.

I personally haven't noticed any powerloss since installing them.

Adding a bit of water/moisture to intake air is a very good performance enhancement; more moisture=higher density air=more power. The purpose of a COLD air intake is to feed cooler air into plenum because cool air is more dense than warm. On a turbocharged engine, an upgraded intercooler will add more than a CAI (won't sound as good, so add both). Any one ever check the temperature of the intake air (w/CAI & w/o) vs. the temperature of the air OUT of the intercooler & out of the turbo. Turbochargers (exhaust driven) do two things: they compress the air and HEAT it-- then the intercooler cools it some. Dollar for dollar for performance forget the CAI and buy a "better" intercooler. Nearly all cars use Honeywell-Garret exhaust driven turbochargers-- that will change in the coming years.

Garrett Electric Turbochargers Headed To Production In 2021

The exhaust can make a turbo RED HOT-- like mechanical power-hungry water pumps are being replaced with electric, so will turbochargers . . . but then electricity will replace gas after that-- sad. I will miss the Sound, Smell, and Fury, but we will all love the instant torque!
