Not sure if I’ll do it, but makes sense that it can’t hurt

Great content , glad we found your channel, really looking forward to more , and stay safe through all the crazy going on in the world 🙏

Great job with the strings to show visualize the airflow!! Awesome demonstration of the functionality

Haha like how I am not the only one to do this too. Just posted this a few weeks back. Good on ya mate

Very neat video, I loved how you tested it with the fan, great video my keep up the good work.👍

I did this not too long ago, twas a pain in the ass but hella worth it! They are functional. Just make sure you use rustolium

Great job! Will be doing the same like you! No holes, thinking of a long rectangle shape

I’d like to see before and after temp readings in the engine bay. Maybe 60mph cruise for 10 miles with and without vents. Wouldn’t be the easier thing to arrange but would be curious.

Good quality video bro subbed

Appreciate the great content. The most functional DIY mod Ive seen yet for the 15+ WRX / STI.

Good work homie! I will be trying this mod on my car here pretty soon and record it.....I also just subscribed.

As a Scooby man and a man of science I love the vid sir. Seems good to me. High to low pressure is how hot air likes to move, and the vacuuming effect of going faster... Can't go wrong. Plz do a fallow up vid.

Good job bro and of course will work big difference i bet on the engine bay temps .. 😎

ooo this is a really good idea! maybe i’ll try this to get the high pressure from the wheel well vented out.

What a top idea. The ej definitely retains alot of heat. 99% of it comes from the turbo.

Him: “…once you put holes in a panel…that’s it…there’s no turning back.” Me: EVERYBODY GET BACK! I HAVE A TIG WELDER AND I KNOW HOW TO USE IT!!!

Howzit🤙 do you love on Oahu? I was born there but live Maui now. Stoked to support a local channel!

Nice job!

Thanks for the info

I knew I was not the only one to think of this modification. You did bet me to the punch though or pull the trigger first. Good on you 👏. The early bird catches the worm. I want to purchase the vented engine bay fender liners before doing the body mods. Four months ago I mentioned to My WRX Channel this modification too as he had installed the vented carbon fiber engine bay interior fender liners. Nice work with the Dremel mini grinder by the way 👍! Curious what diameter were the holes you drilled? Looks to me like 1 1/2 " or 38 mm diameter holes.

This mod works great. It works really well without shrouds. There’s some ducted carbon fiber shrouds ill go with. Trapped heat is annoying

It’s not going to do a very good job at venting the engine bay heat as you’d like but it will. There is a add on vent that you can attach at the top side of the fender near that interior fender shroud that will make more use of venting bay than the wheel well vents The only real function out of this is the reduction of drag and lift in the fender well. Cut a whole in the fender liner to channel that air through it 👍 I do like what you did leaving the support rods in the mesh. Everyone cuts them off and reduces structural integrity. I’m thinking of doing this as well.

APR!! Good luck bro

Nice! just subscribed...

This looks just like My_WRX_Channel’s early build. Same wheels, color...

I have been planning to cut the plastic vent thing. But never knew that i have to drill hole. Very nice. Now i know what to prepare :) I also assume any paint would do for the hole so it wont rust right? Thanks

Nice job man. I think itll definitley work. Try and see if the radiator fans will push out air and feel for the air temp coming out. Hood closed and all while idiling.

I can see this being worth it for a car that's completely panned on the bottom, otherwise you're not really directing much air out of those holes. You've got alot of air from your hood scoop already pushing past your intercooler, over your bell housing and turbo ( since its an STI ) and right out the bottom of your car. Its not gonna help for sitting in traffic either since you're not moving. I can however see this being of some use for drag cars because you're producing alot of heat at a high speed, and if you're completely panned you don't have that heat escaping out the bottom like a road car, or at least not as much of it. The test you performed is only gonna show you what amount of air is escaping while you have a large floor fan directly pushing air down on that side of the engine, with no other currents. With no other air direction modifications done, like venting the front corners of your bumber to force air through the fenders back to those vents, im not sure how much of a return you're getting. Im not saying its a bad idea. I just think it could be implemented with other mods at the same time to make it much more effective.

Did you notice alot of dirt in the engine bay after doing this? Also, instead of drilling holes in the body, why didn't you cut holes on the plastic trim to match up with those 2- oval and circle hole? Or cut holes in the interior plastic portion.

is there actual proof of decreasing engine temps by doing this? Are there trade off's because doesn't that reduce the rigidity of the chassis? Wouldn't that cause more flex?

Any before/after data on temps.... Thanks.

Only thing about heat is that it rises. But good video nonetheless.

you should have done a engine bay heat comparison before and after. nice mod / vid

bro thats a pretty good diy mod. Works it working out? :D

Wonder if this would work on the GR 2008-2014? 😎

The STi fake vent is fake because it’s really not a useful place for REALLY doing anything for temperatures or aero. If you look at real high performance cars the vents in the front fenders are all higher up behind the wheels. If air is being routed into the wheel well for aero, it’s always from low in front of the wheel. NBR has a really functional fender vent cf add on, btw (top of fender).

What is your wheel and tire set up...it looks good than stock.

Where’d you get that alternator cover?

Anyone experiencing dirt or road debris getting in after this mod?

Ideally this would work better if you also cut the splash guard, to be a vent for the wheel well.

Japanese DIY souls thanks nice idea! Idea 0 Yen! Japanese more realization! Tahnks. ------------------------------------------ 日本人もナイスアイデアからDIYでやっている。 アイデアは0円！ありがと。

Bwhahaha this is ridiculous and doesn't do a thing. smh.
