Default Should i get a cold air intake and accessport?

Im debating if i want to void my warranty and get the cold air intake with an access port or not. I wanted to get some feedback from people that have done it. I have a 2017 wrx. specifically i was wondering how you guys get your cars inspected, do you have flash it back to stock or not. Stuff like that. Thank you!

Intake won't give you any gains, and the cold air type that dip down into the fender have a tendency to suck in water and hydrolock the engine. If you're only in it for the whooshy noises, I like the Cobb with airbox.

State inspection isn't going to care about the AP. They start sketching out if you remove your catalytic converter(s).

You cannot void a warranty with an intake or ap, you can however have a claim denied.

Should you get an intake? We don't know, do you want to spend several hundred dollars on a noise maker?

Do not buy an AP if your plan is to try and hide it from anyone (Subaru, etc). Only buy an AP and tune the car if you understand that if something goes wrong, any warranty claim might and/or probably will be denied (depending on what it is).

Plan for the worst and hope for the best.

^I'd go a step further and say no. you should not waste your money on an intake. you dont need the wooshy sucking noises. it will not increase power.

Here's another link to help out on the warranty "voiding" you are worried about... https://forums.nasioc.com/forums/sho...d.php?t=803106

If you want more noise from the intake consider removing the intake silencer from the stock intake(the "milkjug") and subsequently capping the hole with a tennis ball container cap and black duct tape.

Here's a forum link to a DIY for previous years, not too sure how accurate it is with the 17's though.

Thats what I thought, it was fun for a while but got annoying.

On the subject, I still have a Mishimoto intake and COBB AP3 I took off of my 2015 WRX before I traded it in. LMK if you are interested. They should work on a 2017.

Hydrolock the engine? What?
You mean if someone tries to drive through four feet of water? Or on the road?

And considering the 2017 WRX is 58" high, in four feet of water all but the top 10" would be under. It's not like OP lives in the desert.

of all the things to be worried about when using a CAI, I bet 0.05% of ALL failures of an engine due to a CAI include hydrolock.

The bigger issues are good design, getting proper maf scaling, a/f trims, bad tuner, poor installation, improper filter cleaning, pulling hotter air than the factory system, etc.... I'm not saying hydrolock is not a concern, its just VERY low on the risk factor for almost everyone.

What's up Soda. I haven't looked for statistics on the issue, so I'm not willing to agree or disagree with the .05%, maybe a better question is 'what % of CAI users living in NE US experience major engine failure due directly to CAI use?' Doesn't even need to be hydrolock, that's just the most extreme thing I could think of.

Since I apparently need to present a common sense disclaimer, this is just my opinion. Take it or leave it. I would not personally ever use a CAI. You can pull outside temp air into the intake while traveling at any speed at boost and under load using an airbox.

There is absolutely nothing wrong with a CAI provided it is tuned for correctly. Nothing. It is the same exact thing as your OEM airbox, minus the snorkel, provided it is tuned correctly. I've seen 100s of cars with CAIs, 0 of them have had issues with hydrolock.

I don't have any experience with CAI's on the WRX yet, but I have a 350z with an AEM intake that is the style that goes down into the bottom of the front bumper right in front of the tire. It's honestly a pretty terrible design since anytime you drive in a good rain the tire throws water through the vent in the fender cover onto the filter. Right after I installed the intake on the car I hydroplaned on the freeway during a downpour that I was admittedly going way too fast for and ended up in the grassy median. The filter was completely soaked and the car was backfiring and sputtering like crazy, but I had to get home so I drove it very slowly. I let the filter dry out and the next day it was completely fine. Moral of the story: Unless you drive through a river/stream you will not hydrolock your car. Also I recommend the filter wrap bag sprayed with waterproof spray to keep it from sucking up water.
I also tend to agree with everyone else that intakes don't make a huge power difference nowadays. Most of your power gain will come from the tune.

^right.

Hydrolocking! Talk about context not out of left, but out of the left side of Mars.
That should be concern number 9 million on the list of concerns, in order of relevance with 1 being most relevant.

Three takeaways:
1) I can't believe I watched that
2) I can't believe those dudes cared enough about an internet argument to actually make a video testing that (ok I can believe it)
3) Did he really say YOLO before sticking the hose all the way in there? If I ever learn who created the acronym YOLO I'm going to track him down and kick him in the nuts.

I have a Mishimoto Cold Air Intake and a Cobb AP with the Mishimoto Stg1 tune and I LOVE it. I feel like I am driving a different car, I would recommend it to anyone. It does sound bad ass paired with my Tsudo catback I love the sound, just wish it was a bit louder.

Oh let me make one thing clear, I ****ing hate everyone eho is/has ever been involved in Haggard Garage. Period.

It does it does seem petty, but keep in mind that they do run a car channel so responding to viewer comments is necessary. And when the top-ranked comment on half your videos is "It's going to hydrolock" and the other top-ranked comment is "please make a video about how it's not going to hydrolock" your hands are kinda tied lol

But yes, YOLO is ****ing gay as ****.

yolo!!!

don't drive through things you shouldn't driving through (i.e. floods), tune for it, realize a CAI on its own is a useless noise maker. other than that, sure, get the intake. i have an intake on my car... wOOOOOOOOoooooooooshhhhhhh

Coming from a 350z as my car previous to my 2015 WRX, these cars don't have the same vents in the fender well for brake ventilation / air circulation and also they sit a good bit higher than the Z does. Depending on suspension setup,it could sit even lower. Basing what these platforms are made for, and as you and others have mentioned, hydrolocking isn't much of a concern unless you're driving through huge puddles or floods.

If water ever gets that high you'll have all kinds of problem. Not just the intake.

It's been explained to me a good intake allows the turbo to build equivalent boost using less turbine RPM keeping it within design parameters.
