I was really sold on this intake since the first photos of it appeared on this forum not so long ago. In my opinion, this is by far the nicest one I have seen, ever :) Getting it seemed impossible. As AFE Power has contract to supply this part to Hyundai Motors Korea only, it is not possible to purchase outside of South Korea. The fact that stock is limited and only Korean credit cards are accepted very much rule out remote purchase.

The intake, p/n: M6281-AB000 fits following vehicles:
- Elantra Sport GT N-Line / i30
- Veloster JS
- Avante Sport / Elantra Sport
- Kia Forte K3 GT

The intake is available via TUIX mall: ????? and via TUON mall (for Kia) ???? Some info (older) on what is TUIX and TUON: https://thekoreancarblog.com/2014/05/21/hyundai-and-kia-motors-open-tuix-tuon-online-parts-shopl/
You will need local person to make a purchase for you.

The box arrived today, I have asked to have it repacked into a smaller box to save a little in shipping and to prevent 'curious eyes' from checking the rather attractive box. The kit consists of:
- installation manual (in English and Korean - well written)
- air filter enclosure
- air filter element Pro-Guard7® oiled air filter — maximum protection https://afepower.com/air-filter-media
- the intake pipe
- silicone coupler
- fittings/clamps
- AFE licence plate + stickers
- Air filter cleaning/re-oiling kit p/n: 90-50500


The build quality is fantastic. Nice mould, good finish. Nothing really to pick about. Maybe the lack of perhaps a stainless or aluminium frame around the window, but this is just me.. The window itself is great, allows to see if the filter needs cleaning or not just yet...

The installation manual is very detailed, it would be hard to do something wrong - well done!

I will go ahead with the installation this coming weekend. We still have snow in the forecast for the next couple of days and I am still on my winter tires - warm weather is to start on Thursday - I think that is when I will swap the wheels. I would like to drive the car on 18s for a day at least to get a feeling of before-and-after.

To be continued....

Looks very well made. I love that it is totally encapsulated. I hate intakes with the sheild that "seals" against the hood. Underhood heat can easily leak into the filter area.
What you need is a sealed box that connects to the factory snorkel hole on the radiator support (such as this one or SXTH's new box coming soon), and follow that up with a Velossa Tech big mouth intake tube. After a 30 mile highway drive with temps in the 50's and the big mouth tube on my car, I popped the hood when I got home and the stock intake box and tube (I'm waiting for the SXTH box to come out) were cold to the touch.

i completely agree. The only thing im wondering is, will the dimensions of the factory snorkel (without the big mouth) be a bottleneck and not allow the intake to make any more power than a stock box and high flow panel filter?

With both this AFE intake and the SXTH box, the stock snorkel is removed.

I know that. But the inlet to both mentioned intakes is restrained to the factory dimensions at the core support. Im wondering if this is a bottleneck or if these intakes still show roughly the same power gains as the others, but with the obvious added benefits.

I'd say the hole is large enough, only thing that might be a restriction is the "XXX" supports in the middle but I doubt it.

The GT Momentum Intake is in place. The replacement took only about 40 min to complete, only because I was taking some photos in the meantime and I cleaned up the engine bay a little. There are really no special points of install to mention, other than ensuring that the filter's fabric joint is facing down. When I was editing the photos I noticed that the filter's connector is facing perfectly up and visible through the window. I will rotate it 180 degrees.

The shape of the AFE filter enclosure is nearly perfect. Only one of the bolt attachment points is slightly off (see photo), but due to the flex in the rubber mounting bumpers (you transfer them from the factory air box enclosure) it still reaches the threaded mounting hole. One of the bolts is installed inside the enclosure. A small ratchet with long 10mm socket is required. Doing this with an open box spanner is little difficult.

The intake is in essence as quiet as the OE design. Only in the ECO mode, speeds below 30km/h, windows up, sunroof closed and the climate control off one can hear very slight noise of the BOV recirculation. And you really have to listen for it. Difference is negligble and I like it quiet. I did not want a noisy intake. In terms of components' temperature, after about 20 minutes of hard driving, with engine bay definitely warm, the intake box and the intake pipe were nice and cool to touch. The intake does indeed work well in terms of providing ambient temperature air to the engine.

In terms of driving, in the ECO mode there really seems to be no difference in how the car feels. I could not really tell any and perhaps that is why the ECO mode is there in the first place. Easy driving, early gear changes, very little boost and low fuel consumption

Normal - definitely reduced lag when starting to move from a full stop. The intake also seems to remove flat spots from the power band and feels much more elastic. The engine is eager to rev. It is nice.

Sport - well, the initial lag is virtually gone. The engine is definitely increasing it's RPM faster and feels to pull stronger. Torque steer is increased with the traction control off. Too bad I did not have access to a dyno to perform some proper before-and-after pulls. I am not sure what the actual gains are, perhaps not so much in the top end, but there are definite improvements in the low and mid-ranges. I like this 'god mode' LOL.

Overall I am very happy with this intake and if you have some money to spend it is worth it. And it does look good with the Veloster engine cover. Too bad some sort of certificate is not provided from Hyundai Motors TUIX division as I will have to remove the intake each time I take the car to the dealership for service. I would be then able to prove that this upgrade is indeed sanctioned and approved by Hyundai Motors.

Just for clarification on this, it started out as the Veloster engine cover but then quickly became the "updated 1.6L" engine cover. It is used on the slightly updated version of the 1.6 that both Hyundai and Kia are using. It can be found in the new Veloster, the Forte GT and the Soul. Changes that we know of are an increased compression ratio to 10:1 and an electronic wastegate.

TUIX has discontinued inventory of this model (my korean friend helped me order and they refunded her card after a month) and aFE USA only has the newer version that's sealed without the window. Anyone have a source in Korea to get this still?

I have the AFE Takeda stage 2 intake that seals to the hood. I absolutely love it. I paid $329 for it about a year ago. It's paired with the Velossa Tech scoop as mentioned earlier in the thread. I get a tiny bit of BOV noise in both Normal and Sport (no eco on US models). The BOV is louder in Sport but not ridiculous. My wife totally approves and she is picky about upgrades and more noise. Someone mentioned it can't seal perfectly and I agree. I cut out the harder foam our hood is lined with in the shape of the box (after a couple weeks the box had pushed into the foam and gave me lines to cut with), purchased some D-shaped 3M rubber seal, and ran that around the edge of the hole I cut in the foam on the hood and now it seals really well. I was getting some odd high-pitched air noises but they went away after I did the mod to the foam.

For those out there, the Momentum intake from AFE is now on their website, but it doesn't have the window.
