APR PEX Intake System - 2.9TT Audi RS4 / RS5 (B9)

The APR Full Intake System is perfect for Audi enthusiasts seeking the ultimate intake upgrade. Unlike others that address only a portion of the intake system, requiring the inlets and outlets to neck down to the factory diameter for compatibility, this comprehensive solution replaces every component from the inlet scoop to the turbocharger inlet. This eliminates restrictions throughout the system, ensuring unmatched airflow and turbo performance with the largest inlet physically possible.

Key to the system’s superior performance is its optimized design. Making the inlet as large as possible is the goal but space is extremely limited. By maximizing the internal diameter with thin-walled heat-resistant composite materials, APR achieves an impressive 31% more airflow compared to stock. This translates directly into improved turbocharger efficiency, faster spool times, and significant power gains, adding +19 AWHP and +17 AWFT-LBS of torque when paired with the APR Stage 1 (93) tune.

Additionally, the APR Full Intake System is engineered with functionality, performance, and sound in mind. The PEX airbox shields the filter from the engine bay, while its thoughtfully placed cutouts provide additional airflow and a refined engine sound. A massive 7” x 7” washable pleated cotton gauze filter further enhances performance with vast filtration surface area while ensuring long-lasting usability.

Whether you’re focused on unlocking power, enhancing turbo performance, or future-proofing your vehicle for upgrades, the APR Full Intake System is the only intake you’ll ever need.

Features:

  • Complete System Replacement: Includes inlet scoop, airbox, filter, and turbo inlet pipe, eliminating all factory restrictions.
  • +19 AWHP & +17 AWFT-LBS Power Gains: When paired with APR Stage 1 (93).
  • 36% More Airflow: Improved from 484 CFM (stock) to 658 CFM.
  • Enhanced Turbocharger Efficiency: Reduces pressure drop, allowing the turbo to spool faster and operate more efficiently.
  • High-Temperature Composite Turbo Inlet: Enables thin-wall tubing for maximum internal diameter and airflow.
  • PEX Airbox: Heat-shield design with additional flow paths in low temperature zones.
  • Massive Washable Filter: 7” x 7” pleated cotton gauze with a 5.5” frontal inlet and 4” outlet for superior filtration and performance.
  • Future-Proof Design: Billet turbo inlet adapter accommodates larger turbos with a simple swap.
  • All-Inclusive Kit: Includes OEM gaskets, clamps, and hardware for an easy, bolt-on installation.
  • Emissions-Friendly: Requires no tuning and is compliant with emissions standards.
  • Improved Engine Sound: Adds a sporty, refined tone without being overbearing.

Nice fit!
Color: Saxony Blue Melange, Size: X-Large
Great fit. Very comfy. Not too heavy. (Think late spring, early fall weather.) Material and stitching seems high quality. Slightly stretchy fabric. We’ll see how it holds up to wear and washing, but so far so good. I’ve already purchased another in a different color.

Fits true to size and good quality
Color: Black Grey Heather, Size: Large
I gave this 5 stars because I was pleasantly surprised by the fit and quality. The zipper is nice, it zips firm, it's not flimsy like a cheap zipper. For reference I am 5'7", athletic build, and 198 pounds. I ordered a size large and it fits perfect. I will buy more for sure.

Great fit, excellent material. Will buy more!
Color: Cobalt Heather, Size: Small
Great quarter zip comparable to the high end designer brands. Buttery material, well fitted. Runs a bit big so I sized down and it’s a perfect trim cut fit. Will buy other colors. Would like to see some patterns in addition to the solid colors. I’m 5’10” 165lbs and small size fits perfectly.

Perfect for the gym!
Color: Cobalt Heather, Size: XX-Large
I bought 2 (black and blue) and wear them to the gym weekly. They wash & dry very well! They are nice enough for casual wear too. I’ll probably buy a 3rd color soon!
