SRI vs CAI

Hey all,

I apologize if this has been covered already - I did a search but could not find a discussion on the pros and cons.

Trying to decide between an SRI and a CAI.

From what I read on the interwebs, there seems to be a whole lot of hating on the SRI's for "just sucking hot engine air, worse than stock"
I gather though, that the harder, ridgeless piping probably increases airflow, but I can see the science behind the hot air, and the filtration not being as good as perhaps an air box...

CAI on the other hand, most people have positive things to say, except for "hydrolock". Depending on where you live, this may or may not be a problem. For me, it's certainly a risk, as we sometimes get a heck of a lot of rain, and some streets flood a few inches as well.

I'm not worried about the HP increases, as I'm not going to be racing, or posting Dyno results on my fridge.
I do care about making the car sound a little louder, as I find it's a bit quiet in the cabin, especially with any sort of music on, and also I hear the throttle response improves with both of these options.

Any thoughts?

I'm totally with you on increasing the cabin noise a little as well as making the car sound better :eek:.
I have only have had good experiences in the past with AEM and their CAI. Because of your mentioned concerns with the SRI I never bothered with the latter and went right with the CAI.
AEM, to my understanding, still has not yet produced a CAI for the VT, but I hear good things about Injen as well, just not sure if they have an CAI application for the VT yet.

Well, mainly what you have been reading on the interwebs (I assume) is mainly related to NON-TURBO vehicles.. Am I right?

With a SRI @ WOT you are not going to be getting 'hot air' into the intake. The only time the air being sucked in will be warm/hot is when you are just sitting there and there is no airflow through the engine bay.

Hydrolock with a CAI (especially on the V and how they get setup) is so rare it is silly. The filter has to be sitting SUPER low for it to even be a concern. On top of that, with the splash guard, fender, bumper, fog light, the filter is blocked off from any water getting in there (unless you drive through a pond)

I'm not worried about the HP increases, as I'm not going to be racing, or posting Dyno results on my fridge.
^^ Without going further into the CAI vs. SRI debate, the SRI is surely for you.

Back to SRI vs. CAI "ON A TURBO CAR"

There isn't going to be much of a difference on most turbo cars if you decide SRI vs. CAI. The turbo compresses (and really heats up) the incoming air, whereas a non-turbo car is just sucking in the air.

While a CAI will still be a little better on a turbo car, it isn't going to be night and day (typically)

With the filter in the stock area and with the stock snorkel system removed it makes a pretty good SRI setup. Going to a full CAI is going to cost more (more piping) and I don't think the results will be worth it. Obviously, the cooler air you start with, the better but with the turbo doing its work it isn't as significant.


If you have any mechanical ability what-so-ever, I would HIGHLY suggest building your own SRI/CAI. you can get a pipe cutter from harbor freight for cheap and the tubing/filter/clamps/couplers online quite cheap also. There is nothing made yet for the VTurbo that I know of.

Haha..... Well, I'm out since I'm not really that "able bodied" ;). I can fix 60's & 70's motorcycles though :eek:
Also, since the diference between the SRI & CAI on this car is so little, I think I will also lean towards the SRI now. TY

Always a great help Turbosocks :)

I was leaning more towards SRI based on cost, look and all.

In retrospect, I think you're right on the interwebs research... All I really did was look up "SRI vs CAI" and flew from there. I think the last forum I was on, was an Accord forum.

What you're saying makes perfect sense. I think I just needed some positive feedback!

Just found this poking around, can't imagine that the fit from the NAV would be that much different to the VT, or can it....?!?
Injen Cold Air Intake 2012 Hyundai Veloster 1.6 (Converts to Short Ram)
Item # SP1340
Price $229.87
Found on: injenairintakes.com

TurboSocks, any input on engine bay differences or would this CAI fit on the VT?

it is actually a LOT different..

Since the VTurbo is.. well.. turbo'd the turbo is on the back of the engine and so is the intake.

On the non-turbo model, the intake is on the FRONT of the engine.

The intake manifold and throttle body is in the same spot on both vehicles but the intake piping is reversed..

see these pics...

this + removing the bypass hose would be the best and cheapest way to gain a ton of sound and a bit of power.

It won't cost you more than about 20-25$ and will make worlds of difference in the noise department.

The stock intake hose will probably flow quite well and you wont gain much but looks from a 'real' SRI.

Doing a filter on the stock intake hose + removing the bypass hose could potentially save you ~200$ to get almost the same result from an SRI + BOV.

just to add another option

k and n drop in air filter , you get more flow than a stock filter , and if you look under the lid of the stock air box, theres some crazy noise baffel in there , it snaps out allowing a bit more flow as well.
