PROFILE

The #1 power-adding bolt-on upgrade for your for your 4.0T!  The ARM 4.0T Inlets greatly improve airflow to your turbos by replacing the restrictive OEM inlets.  Upgraded inlets for the 4.0T are so essential that most tuners list it as a required upgrade for any tune above a base Stage 1 tune. 



Installing the ARM 4.0T Inlets will eliminate any restriction of the induction on your 4.0T, allowing your turbos to spool faster, generate more low-end torque and produce higher peak HP, for snappy launches and high trap speeds! 




The ARM 4.0T Inlets are a direct replacement for the OEM inlets on the S6, S7, and RS7.  The ARM 4.0T Inlets will fit any turbocharger setup that uses the OEM inlets.  The ARM 4.0T Inlets are even a substantial improvement over the RS inlets, which have a smaller diameter than the ARM 4.0T Inlets. 



CONSTRUCTION

In order to vastly improve airflow over the OEM inlets while still making this a direct replacement, we utilized a 6-Axis machining process to produce the largest piping possible in the space available.  This process was required to contour the inlet piping as to maintain 63mm diameter piping throughout the entirety of the inlets.  The result is the largest inlet piping possible while keeping an OEM-like setup. 



The machined inlet flanges transition to 63mm aluminum piping which extends all the way to the 6-Layer reinforced silicone couplers.  These couplers are extra durable to prevent any deformation during induction on demanding builds.



Connected at the other end of the silicone couplers are the J-Pipes from the ARM 4.0T Intake.  The ARM 4.0T Inlets are designed to be paired with the ARM 4.0T Intake which extends the air filters deep within the passenger side airbox cavity to access the coolest air available in the engine bay. The ARM 4.0T Intake Kit utilizes two dry media filters, as opposed to oiled filters which can damage the MAF sensors.  Each filter provides a total surface area of 68 cubic inches, for a total of 136 cubic inches of filter area for the pair. 

Unless you are planning a custom setup of your own, the ARM 4.0T Intake is required to properly fit the ARM 4.0T Inlets as the ARM 4.0T Inlets do not include air filters.  The ARM 4.0T Intake can be added for a discounted add-on price using the options at the top of this page.




 


If you want to maximize the performance of your ARM 4.0T Intake setup, you will want to opt for ARM 4.0T Heat Shield which helps separate the cold air feeding the intake filters, from the hot air generated by the engine.  This will result in cooler intake air temperatures.  The ARM 4.0T Heat Shield makes a tight seal to the hood, maximizing the amount of cold air being ingested by the ARM 4.0T Intake system.

Supportive and Comfortable but Size Down!
Size: X-Large, Color: Navy
Very supportive for the big chested girlies! Material is comfortable and sweat wicking. I’d recommend sizing down for a snug fit.

Nice fabric, comfortable, easy maintenance
Special Size: 27.5" Full Length, Size: Large, Color: Taupe, Special Size: 27.5" Full Length, Size: Large, Color: Taupe
I ordered a medium and they’re actually a size large. And they are just too large. I should’ve gotten the small, as recommended I thought I was ordering medium and I think I would’ve been OK with a medium, but where I usually wear a small and they sent me a large. It was just ridiculously large. They are lightweight and they are warm. I’m a senior and I’m thin so I get cold very easily especially in early morning and evening, so I like to wear them in the morning for my walks/yoga , they also work nicely under a longish skirt so it’s not so sheer… will definitely get more but will go with the small size. Just for reference, I’m 5 foot seven I usually wear a small or a size 5/6 usa size so these were too large, particularly in the waist just overall they were too large, but I think even if I got a small size they’re still gonna be kind of large in the stomach. I have an hourglass shape just for reference, but they are very comfortable, and I love the fabric. I am keeping them because I like the fabric and I really need them. I just will not wear them out of the house right now because they’re not fitting properly but next go round we’ll get the right size. Price was right they were having a sale so it was a bit of an impulse buy. But hello it was only 10 bucks! so that’s why it’s not worth sending it back for me. Overall, very nice quality and would recommend. Cats like the fabric too! 😸

Buttery soft and flattering fit
Special Size: 27.5" Full Length with Pockets, Size: Small, Color: Taupe
I love these leggings! They are buttery soft (as advertised) and have a very flattering fit. Also the grey/beige color is really pretty. About to buy another pair in black! Highly recommend!

Not for people over 5'6"
Special Size: 27.5" Full Length with Pockets, Size: XX-Large, Color: Slate Grey
These are definitely designed for shorter people. They get 5* because they're still low cost and decent quality on fabric. Just have to pull the waist up because the calfs are not designed to be worn as capris and pull the entire leggings down. If it sized up one more then they'd just fall down because of the waist. So waistband fits as expected. They're just also for shorter people than me.

"Heather" and Non-Heather Colors are Not the same Fit & Material
Special Size: 27.5" Full Length, Size: Large, Color: Space Dye Slate
I bought these in one of the "heathered" colors and loved how soft they were. They are really comfortable and stretchy, thick enough that they can be worn on their own. They are not a perfect fit, but fit well enough and I can overlook this because of how smooth they feel. I wanted to try other colors and only realized after purchasing that the non-heathered colors were a different material. I was able to return them but they should probably be listed as a separate item. They have an entirely different fit and texture and I would not recommend. Five stars for the heather colors, one star for the non-heather version.
