The Options

S-FLO Carbon Inlet Tube:

The S-FLO Carbon Inlet Tube is the largest amongst its peers, with impressive adaptability to facilitate maximum gains. The colossal 4.5” S-FLO Carbon Inlet tube bridges the gap between the turbo inlet pipe and the factory airbox seamlessly.

The S-FLO Carbon Inlet Tube is for drivers looking to extract the most out of their factory airbox while increasing throttle response.

S-FLO Shortie Carbon Intake:

The S-FLO Shortie Carbon Intakes replaces the factory airbox with a massive S-FLO Filter with frontal opening toting a 30% increase in filter surface area, and a 4.5” carbon elbow. All firmly planted via a bespoke CNC laser-cut stainless support bracket.

The S-FLO Shortie Carbon Intake is the perfect configuration for drivers looking to uncork beloved turbo noises out of their RS 3.

S-FLO Open Carbon Intake System:

Combine the S-FLO Carbon Inlet Tube with the Shortie Carbon Intake, and you have the impressive (and very vocal) S-FLO Open Carbon Intake System.

A full 4.5” diameter configuration from S-FLO Filter to turbo inlet coupler, this version delivers an increase of 7 hp and 3 ft-lbs of torque at the wheels with an ample dose of turbo induction and diverter valve sounds with each rip of boost.

S-FLO Closed Carbon Intake System:

The S-FLO Closed Carbon Intake System combines each component of the S-FLO suite and adds a bespoke carbon air box. Spanning the entire width of the grille, the S-FLO Closed Carbon Intake is capable of collecting all of the ram air from the front of the vehicle to feed it into the S-FLO Filter.

Thanks to the 2x2 carbon fiber construction, heat soak is subdued during hard driving while the increase in air box volume ensures the 2.5T never runs scarce of cold air.

The S-FLO Closed Carbon Intake System unlocks 17 hp and 6 ft-lbs of torque at the wheels, and is capable of handling any higher-than-stock boost level thrown at it.

Upgrade path:

The S-FLO Carbon Intake Suite is modular by design allowing an easy evolution from the S-FLO Inlet Tube or S-FLO Shortie Carbon Intake to the full S-FLO Carbon Intake Systems (open or closed).

Go all-in with the S-FLO Closed Carbon Intake System, or tackle it in phases. Your call.

S-FLO 4” Coupler:

The S-FLO Carbon Inlet Tube, Shortie Carbon Intake, and Open/Closed S-FLO Carbon Intake Systems come complete with a 4.5” to 3” couplers to mate to the factory 3” turbo inlet pipe. The S-FLO 4” Coupler transitions from 4.5” to 4” to accommodate aftermarket turbo inlet pipes that are 4” in diameter.

What’s in the box?

Chosen S-FLO Carbon Intake configuration, S-FLO Filter (if applicable), bespoke CNC laser-cut stainless support bracket (if applicable), coupler(s), and all necessary hardware.

Notes:

  • The AWE 4.5" S-FLO Carbon Intake Suite is for Racing Use Only

    Flattering fit
    Color: Dark Green, Size: XX-Large
    This sweater is thick and stretchy but holds a nice shape, and is flattering on the body. The sleeves are nice and long too, which I really appreciate, being a tall person... the button detail is a great addition. True to size. I haven't washed it yet, and I imagine, based on the kind of woolly knit it is, that this sweater will eventually pill... but for now I'm enjoying being cozy and stylish. The deep green color is almost black green. I LOVE IT.

    Love it
    Color: Dark Green, Size: Small
    I got the dark green. Love the sweater and it's warm. I do layer the sweater as well. It is as pictured. Size is perfect to me. I like sweaters to be longer and a bit wider in case it is freezing and I need to layer it. This sweater is perfect for layering. It comes closer to my backside, it is a little wide and not snug, and I like that the sleeves come over my wrists

    Still soft but looks terrible after 1 wash. Save your money
    Color: White, Size: Small, Color: White, Size: Small
    Update: sweater looked great when I received. After 1 wash it looks terrible. Looks like it’s been washed too many times, material fuzzy and piled. After wearing it once, it snagged and the knit pulled through. I would NOT recommend. I had such high hopes. Save your money. Very nice sweater, especially for the price! I love the details of the buttons on the sleeves. It is SO soft. It’s not super thick as I can see my skin through it when pressing my hand up against fabric. However, it’s not see through when wearing it. It’ll be perfect in cooler weather and perfect in the winter with a coat but won’t cause me to overheat when in a heated environment. I do feel like it runs big. I could have sized down a size. Although I’m not sure if it’ll shrink after a wash or two.

    Disappointed.
    Color: Blue, Size: Large, Color: Blue, Size: Large
    This sweater is so comfortable and very soft. It fits well in a flattering, oversized way. But after one wash it is pilled everywhere which makes it look old and shabby. It’s at a price point where I feel compelled to return it.

    Perfect for casual wear and dressy style
    Color: Dark Green, Size: Small
    This sweater is soooo soft and the color is so rich. The fit of it is perfect, not too tight and not too baggy, just right and I used the size guide to pick my size. Just for reference, I am 5'3" and 130lbs, 38C bust. It's well made and washes great. I chose to hang dry mine as I typically don't put any of my sweaters in the dryer to dry, just to fluff them. I have this one in two colors, the green and the tan/beige and I would say they are both a true representative of the color shown.
