The APR 4.0T EA825 Intake System is here for the Audi (C8) RS6 and RS7!

The APR Intake System is a substantial upgrade for the 4.0T EA825 engine. It offers significant horsepower and torque gains through a high flow design that greatly increases airflow while reducing pressure drop.

We've upgraded every part that actually translates to increased performance. Throttle response sharpens, as the system lets your engine to breath more freely. This causes the turbochargers to work less hard, which directly translates to the gains you feel. On top of that, the stunning carbon fiber and aluminum design looks fantastic in the engine bay and adds a pleasant auditory note to the engine. The filter is washable and reusable, and the cast aluminum turbo inlets use adapter rings with ideal entrances, making them compatible with larger turbochargers. This lets the system support even higher airflow levels, with low pressure drop, and even more horsepower and torque as you continue to mod!

Design Overview and Testing:

There was no component overlooked in the search for performance; the airbox, filter, couplers, and turbo inlets were each extensively analyzed and modified for maximum flow. The upgraded APR filter unit, featuring a low restriction cotton gauze media, flows 8% more than stock without sacrificing air quality. Flow is further improved by 52% larger airbox outlets, and 93% larger turbo inlets. The significantly improved APR turbo inlets are compatible with turbos featuring up to a 29% larger inlet port; various inlet adapters ensure that the APR intake will provide optimized flow for a wide range of turbos. Overall flow improvements of the intake result in a 50% reduction in pressure drop compared to OEM. The APR intake flows 19% less than the theoretical maximum supported by the OEM turbo inlet port diameter; a significant improvement compared to the OEM intake which flows 37% less than the theoretical maximum. Such significant improvements in flow quality and quantity are manifested in faster throttle response, reduced strain on the turbo, and increased efficiency which translates to more power. On the Stage 1 (93) APR RS6, an additional 47 AWHP and 38 AWFT-LBS of torque, to all four wheels, was measured on our calibrated chassis dynos. Whether you are looking to improve the performance of your stock RS6, or pushing the limits with larger turbos, the APR intake will support your efforts.

Features:

  • +47 AWHP & +38 AWFT-LBS at the wheels measured over stock (Stage 1 93)
  • Carbon Fiber airbox with 52% larger airbox outlets
  • Smooth and high flow turbocharger inlet pipe couplers
  • 93% larger aluminum turbocharger inlets with adapter rings for larger turbochargers

  • Inlet piping diameter is maximized from the airbox outlets to the turbocharger inlets
  • Inlet piping addresses the main system restriction
  • Billet turbo adapter rings make fitting this system to larger turbo possible
  • Emissions friendly

    FANTASTIC FIT
    Size: 16 Plus, Color: Washed Blue
    I'm a 4'7" , 65 year old woman. Due to abdominal issues I needed jeans that give that extra something on the waist. I've tried on just about every brand of jeans ranging in size from adult/junior 6 to 12. If they fit on the legs the waist was huge. If they fit on the waist the legs and butt had enough room for me and a friend. I was resigned to wearing yoga pants and leggings with big shirts. My son mentioned that he loved the Amazon basics men's dress slacks, so I figured why not. First I looked at women's and juniors, and I knew from the measurements that I was still stuck. Then I remembered that about 15 years ago I'd buy girls pants (I was a size 12 in kids at the time) Looking at the sizes I knew a 12 was way too small, then I saw the 16 plus. With hesitation I bought them. Well glory be miss Agnes, THEY FIT. Comfortable, real jeans again. Sure, I have to take them up about 6 inches, but that's fine, not a problem. I'm just so happy to have real jeans again !!!

    Love them!
    Size: 7 Slim, Color: Washed Blue
    I did but expect these jeans to fit so well and look so nice on my daughter. Hands down the best jeans I’ve purchased for her, much better fit and quality than the other stores! The length is perfect, but it’s a little snug in the waist. Still a great fit with some stretchiness! Great value!

    Great pair of Jean and great price!
    Size: 14, Color: Washed Blue, Size: 14, Color: Washed Blue
    I can’t believe these were only $13. They feel and look like quality jeans, very basic/simple boot cut. My daughter says they’re stretchy and comfortable. I ordered her a size 14 (12’s fit her waist but are always too short) She’s 11 years old, 5’ tall, about 80lbs. The waist adjusters were great for the perfect fit.

    Amazing jeans! My daughter loves them!
    Size: 7 Slim, Color: Washed Blue, Size: 7 Slim, Color: Washed Blue
    My daughter is really slim but tall. She is 7 about 50 pounds. She loves them and I’m so happy because all the other jeans that I buy I have to return cuz they are all too big on her. The jeans are stretchy and feel much more expensive for the price! Great quality! I will be ordering more for sure!
