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:

    This is Willow The Dog’s favorite toy!
    There is not much that needs to be said about this, frankly, amazing dog toy find. After about 6 months, Willow absolutely loves this seemingly indestructible, soft stick toy. She was born a stick dog and has always enjoyed fetch with tree limbs, balls, frisbees…And like most dogs, loves tug-o-war and chewing. I thought I was buying a <$4 toy stick that I expected my girl would destroy fairly readily. What I actually received was something that didn’t really match the description because it had MORE features and uses than I expected. Anyway, the short of it is in the video. What she loves: Fetching: I don’t know how dogs see colors, but I can confirm that my dog finds this toy highly visible day and night. This claim is based on my observations of how she retrieves this toy compared to real sticks, yellow and blue tennis balls, a large real bone, and rope toys both night and day, as I work late, so much of my one on one time with our pup happens around midnight to 1am with no outdoor lighting so we don’t disturb sleeping neighbors as much. Additionally, I find this toy highly visible in all conditions, which would make finding it in the grass after Willow is worn out and goes inside easier, except that she loves the toy so much that she always brings it in with her. Tug-o-war: Being a soft, ultra-durable material, this toy eagerly pulls double duty as a tugging toy. Dog teeth sink into the orange material by compressing it. They do not puncture the orange part, or at least not that I’ve noticed while casually examining it, making this toy last indefinitely, so far as I can tell. The size of the stick is roughly an inch in diameter and maybe ≈14-16” long, so it is, I think, a perfect size for my medium sized Australian Shepherd’s mouth. She can grip it solidly in her back teeth, side teeth, front teeth, and even if she has only two or three teeth in just a corner, she can always get a good, comfortable grip. No sharp, jagged edges of frayed plastic to abrade or irritate the inside of Willow’s mouth, gums, or cheeks and no orange material breaks off and gets swallowed. The blue material is somewhat more rigid, like a plastic, BUT is still fairly soft and while it does show some bite marks, it is still quite durable and is, I will estimate, at least 95% intact after about 6 months of average three or four 15-20 minute sessions each week. Additionally, the size happens to be perfect for my large hands, but also feels like it is appropriately sized to be easily manageable by most people. This toy is VERY flexible and gives both Willow and I excellent maneuverability and pulling left to right and up and down and back and forth and to and fro as violently and aggressively as we can manage with out the rigidity of other objects shifting uncomfortably in her mouth or my hand. The stick is long enough to accommodate both my large hand and her mouth, even both of my hands on either end with her biting in the middle. Chewing: This not Willow’s favorite chew toy, but to be fair, it isn’t really marketed as a chew toy, so I feel the degree to which it fulfills that function is “good”, which I consider to just be an added bonus feature AND an extremely good value for the money. Anyway, she brings it inside when we are done playing outside and chews on it occasionally, apparently when she wants a break from her seemingly endless and evidently boring selection of toys, enrichment gadgets, kids, neighboring dogs, and family cats. Summary: At $4, even if your dog picks it up and walks on her or his hind legs to dispose of it immediately upon presenting it to them, it will be worth it just to see that, but if your dog loves it as much as mine, you might, like me, be so pleased with it's contribution to your dog’s life, you may start doubting your sanity when the strangest thought creeps into your head as you actually consider “refunding the seller” by sending them an additional $3.94 because they absolutely deserve to be paid more for this wonderful toy. Enjoy!

    Perfect Toy
    My dog loves this ! It is very sturdy, very strong, but flexible. It feels soft, but seems chew proof, even for my 100 pound Cane Corso. The stick shape is more practical than a ball; it doesn't roll off or get lost under furniture.

    Good toy, strong yet soft!
    This was one of my best toy purchases for our GSD! He’s a rough playing dog with a hard mouth! Toy destroyer! This he loves to fetch, tug, carry, and chew on. I never really expected it to last when I got it. Surprise! Almost two months of rigorous daily play and it’s still almost like new!

    Great cost effective chew toy for an aggressive chewer
    Bought multiple. Still have a few in the package because the others are still going strong. Nice heft to throw them a good distance, durable enough for a heeler that is a very aggressive chewer to not destroy them after a month, and easy to see when they leave them in the grass. Good size, Good weight, Excellent durability, and keeps their attention longer than a actual stick.

    Fun toy for dogs
    Great toy for my dog. She loves when we throw it in the backyard for her and so far she hasn’t chewed it apart and she’s a big chewer. It’s bouncy too which makes it even more fun to chase. Great toy for the price
