Are air scoops worth is?

[Casper_gt2]

Hey guys I just bought a gt2 last month and have been seeing the velossa tech air scoops around. I have the afe takeda intakes and they've been doing fine with lowering intake temps, but are the air scoops really worth spending the money on? Or am I fine keeping the stock intake system with the takeda? Thanks a lot!

Just remove the intake horns.

Assume you mean the intake inlet elbows. I agree.

I am curious as to what the actual power difference is with these removed. It's certainly something given the testing others have done. Just no dyno's comparing stock to no inlet elbow.

Apparently it is called an "air duct", but that is a little ambiguous.

I'm running Velossa snorkels + stock air box + upgraded panel filters. I can tell you that the air duct assembly is ridiculously restrictive, and when I removed it I was perplexed how Kia could design an air intake path so convoluted.

If the AFE is pulling 100% of its intake air through those air ducts (and doesn't have any other path to intake air) then I would definitely remove the air ducts. There is no downside, and it's free other than an hour or two of effort to drop and re-install the bumper.

Hard to say if you will feel a power increase however. But, with the stock air boxes in place, higher flow panel filters, and the snorkels in place I did notice a mid-upper power increase over completely stock.. That was with a JB4 on Map2. I now run the same setup on map5 e30 and can hold 20 lbs of boost to 6000rpms.

The snorkels do a nice job of "ramming" air into the intake at higher speeds (like 3rd and 4th gear). On my Veloster N I noticed that got an extra 1.5 lbs of boost in the upper RPMs at higher speeds with the JB4 after I installed the Snorkels. I don't see the same thing with the Stinger, but it in general holds boost better into the upper RPMs especially with the waste gate adapters installed and adjusted to my liking.

Personally I'd run the snorkels with the AFE intake. They're fairly cheap and you'll already have the bumper off anyway to remove those stupid air ducts.

Someone on here had done a test on air temps with and without those ducts, and found that it was comparatively cooler without them. I reckon the snorkels provide at least some marginal improvement to intake temps while at speed, but simply removing the ducts is a good improvement.
I've also noticed that it's easier to hear the intakes without the ducts, which isn't a bad thing.

I agree, however wanted to hear the details of why you think it's restrictive.

I was thinking about this last night and I think it makes sense. My take is that it's because the ducts take in air at the top of the bumper where heat builds up from the engine.

This was the best view of one of the stock intake ducts I could find:
Ebay listing of one of the stock intake ducts

There is a big restriction between the air intake grid and the rectangular outlet - it's not a smooth bend with a consistent cross section (or as close as reasonably possible). plus the intake grid is pointed vertical and right next to the bumper shroud with little space. I can't help but wonder if the convolution of these is meant to reduce noise at the expense of a narrower opening for air--like most cars I've worked on. Removing the intake duct should help the car breathe better - it's easier to breathe through your mouth or a large, fat straw than through a coffee stirrer. Adding the scoops? Who knows. I have them and I can't complain.

Appreciate it! Got snorkels otw now

You can find pictures here as well as some testing from an Australian Stinger owner done years ago, performed with a vaccum gauge attached to the stock air box. Removing the ducts made a pretty substantial difference in reducing the vaccuum observed inside the airbox at full throttle. But, it really is easier to understand if you see it first hand. I encourage dropping the bumper to take a look ( and to remove them ). There is no downside.

Yep, I did on my 2019 G70 and talked to the Aussie that did it. I was just curious on your take. I like gathering lots of opinions.

Here is some 1/4 mile runs with 2 stock Stingers. One with Scoops, the other fully stock.

Is there any tutorial on the removal of the stock intake channels? Really want to do that but unsure if i can do it myself.

Search YouTube. A few videos on it. Pretty easy

Looking at trap speeds 1.5-2mph increase with the snorkels is pretty good -- about what I'd expect. You can definitely see the difference getting into the upper gears at higher speed.

Agreed--I think there's a lot of evidence there that the snorkels are more free-flowing than the stock intake ducts.

What would be interesting to see is a comparison of the snorkels vs. just removing the intake ducts.

Look up bumper removal for the Stinger, taking the factory ducts out after the bumper is off is the only way, but it's pretty easy.

Watch this.

They look cool, but i have not seen any real data showing significant increase from air scoops on a daily driver
