This is a dope video! The Cobb SF intake gives the best AF readings for my car as it turns out. All the OTS tunes are MAF based tunes and the Cobb intake is designed to run a high MAF calibration. Another intake like AEM or Perrin feature smaller, closer to stock piping, different maf locations and thicker filter densities than Cobb's design. It's honestly probably safer to use a smaller diameter intake with the stage 1 and stage 2 ots maps, but definitely not the stage 1+ maps, not without a protune. A stage 1 tune and the stage 2 tune use the same 383.13 MAF calibration as the stock tune does, versus the Stage 1+ SF map at 490.25. If you go stage 2, look at the differences between the flat-flange downpipes (grimmspeed, HKS, MAPerfromance) and the bellmouth downpipes(Cobb,Invidia, TurboXS) that will tell you whether or not you may need to go Higher or lower wastegate duty. I have a Grimspeed DP and I run the HWG map because I make 16.8 psi on the normal wastegate map due to mechcanical limitation, but with the HWG map I make 18.5 psi.

Gotta love when they forget to send the destructions very helpful

Super detailed and helpful. I followed exactly the same to install the stage 1+ kit for my 2021 STI. Thanks bruh.

awesome video. i followed this to the tee, and installed my sf cobb intake today. very detailed DIY. Only thing you didn't mention is that I would drop my 10mm socket into the engine bay! it's gone forever now..... !

I just picked up this package for my 2020 wrx can’t wait to insteall it 🤙🏽

Damn I can’t wait for my stage 1+ kit to come in. Great video guys!

Great job!!!! 💪🏼

I would love to add this to my 2019 STI but I don’t wanna void my factory warranty. For now I just added the Grimspeed Dry Con drop in filter.

did the motor blow up yet?

Awesome I got scared for a bit when it took awhile to start.

Till this day with all the videos I seen after remapping, no one lets the the fuel prime fully lol but grats on the stage 1+!

really want this but dont want to void the warranty and still have 37k miles left to go haha. Good vid man

How is this holding up after 3 years? Any problems

Great video! I'm about to do the exact same on my 2020 STI. Can't wait!

So cool

Man this cobb stage 1+ is really tempting for my STI but I want the warranty 😭

It seems this comment section is pretty knowledgeable, maybe someone can help me. I have a 17 STi with a GS catted dp and a catback, and obv a AP. I haven’t tried any different map other than what was recommended when I first married the car to AP. My af learning has spiked recently, from normal ranges to 22-25. That being said I was in the middle of putting an intake in, but had to stop cause I didn’t know the hose leading to the interior was just for turbo noise. So I put everything back now I have high numbers, any ideas?

Mine just arrived today and I'm going to install it after work!! Thanks for making this video. I will also be installing an exhaust from Borla. Which tune would you recommend I selecting--stage 2 or keep it similar to what you picked in this video (stage 1 plus)?

Hey.. i just install the ap and cobb intake (which is stage 1+) Im little bit confused what map should i be running since it’s my first mode.. or do i have to follow from ur video (stage 1+ sf 93 normal boost select) which that you saying on the video.. Need Help please..

good vid brotha

You should do turbo inlet. I did intake and inlet n ap

Installed it without the rubber... whoop

I just installed this intake for my 2020 STI, had the same issue with MAF sensor wire length. Are you still positioning your sensor wire like that? It got me worried a bit cause i'm not sure if the wire touching the filter will cause any potential issue. I ran stage 1 map with AEM intake before but switched to Cobb for the sound haha. Thanks!

Any problems so far? Im seeing a bunch of cobb ots tune 50/50 side. Some pll say it causes the car to blow pistons or yet blown motor. Is the cobb tune safe? Orl just get it pro tuned? So confused some ppl have success with no problems some ppl end up blowin motors / pistons

wanna do this but warranty

Quick question, do you need the air box cover? If I get one in mine I’d like to make sure the intake is visible when I pop the hood…

Hi bro. I hope so see my comment i have a Sti 18 with aem intake and nameless exhaust does the accessport support this mods i can ru the accessport with the aem intake ?

OEM snorkel doesn't fit? Does the Cobb intake come with a new snorkel then?

How big was the difference on the accessport compared to stock , wanna get one as my first mod

Does it matter what waste gate you put it at?

The 2020 STI's stock tune is pretty good and upgrade from the older VA. Do you think the Cobb AP tune would be better? Also, I'm thinking of either an SF intake or a DP with the Cobb OTS tune. I thought about a protune, but the shop owner I'm working with said it wouldn't be worth it until I get more mods such as flex fuel or fuel upgrades.

Hi, I would like to know do you think is better to start with the map that you said or we can still go the 93 oct but the hwp? What do you recommend thanks a lot

how much did you gain for HP by installed Cobb intake and access port stage 1+ since the car already has 310hp

My silicone hose is smaller than the intake, did you have this issue?

ill get this stuff when my warranty ends gatta be smart

Do you have to download anything from computer before you install the AP to your car or just install it straight out of the box?

Hi is there any difference between big sf intake versus a regular sf intake? i have a cobb ap and plannin to go stage1+.. but what confuses me is the big af and regular sf intake and also do accesport have map on both size of intake?? thanks for any input! just bought my accesport 4 hours ago lol and got a stage 1 tuned 91 octane :)

Starting engine takes that long?? So with that tune every time u start it engine it takes like 5 seconds? That normal? Thanks….cause im debating if I should get mine tuned by professional with dyno…or just do it cobb accessport way….thanks

My maf sensor literally won’t come off

have you had any problems with the OTS tune?

I have the Cobb sf intake... which map would be safe to use? I’m currently using acn 91... not sure if it’s the right one

why does Subaru ship the cars with the stock tune if it is so bad?

Bro don't tell people to get this if it's a brand new car. Last thing u wanna do is avoid the warranty cause these certainly well

Is it safe to run Stage 1+ with any OEM intake with a catback system? Or does it have to be a Cobb intake?

Can I run cobb stage 1+ OTS Map with just a axleback muffler delete ? Or would I need a catback ?

Does the Accessport allow you to burn Lean or Rich? I want mine to spit a little 🔥. 😅

how are you stage 1+ but saying you have catless dp in description? dont you need to be stage 2 for a downpipe?

I’m scared to void my warranty. I only have 9k miles

"little tool" = allen wrench

Did you guys disconnect the battery beforehand?

They say in the video that stage 1 is without an intake and stage 1+ is with an intake. This is incorrect. 1 is for the intake and 1+ is for an intake and cat/axle back exhaust. This incorrect info in these type of videos is how people mess up their engines and turn around and blame the map and/or the product installed. Do your research wisely before listening to these type of videos!!!
