Introducing the APR Full Intake System for the Audi RS4 and RS5 (B9) 2.9T EA839
APR is proud to unveil the Full Intake System for the Audi RS4 and RS5 (B9) 2.9T EA839—an all-in-one solution designed to deliver maximum airflow, enhanced turbocharger efficiency, and real, measurable performance gains.
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 on our APR Stage 1 (93) equipped RS5.
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. Testing Results That Speak for Themselves The performance of the factory intake system is no match for the APR Full Intake System. The stock setup is limited to a maximum flow of 484 CFM at 28” H2O, whereas our full intake system achieves a significant 36% improvement, flowing 658 CFM under the same conditions. This increase in airflow is paired with a dramatic reduction in pressure drop across the system, allowing the turbocharger to spool faster and operate in a more efficient range of its compressor map. The result is not just theoretical—it’s power you can feel.
On our Stage 1 (93) tuned Audi RS5, simply installing the APR Full Intake System delivered an additional +19 AWHP and +17 AWFT-LBS of torque, proving its capability to unlock your vehicle’s full potential.

Great so far
Size: 6 FT, Color: White
The first thing I liked about this is that the on/off switch has a mark on the ON side, unlike my last Belkin power strip, which had a switch where you couldn't tell which side was on or off. That Belkin was remote, which I really wanted, but the Belkin remote never worked reliably even from the start, so I'm happy with a surge protector without a remote but where I don't have to guess whether it's on or off if I can't see the light on the device plugged into it. Very reliable and solid performance so far and I also especially like the generous amount of space between the outlets - enough for the biggest plug without getting crowded. Also it's not heavy & clunky like some. And the 6 foot cord length works great, too - a big difference with the usual 5 foot cord. Also has 2 USB slots which I can use to charge my iPhone and USB chargers. All this at a decent price and it's not clunky or ugly. Have been using it daily all day for 3 months now with zero problems.

Very Good Purchase
Size: 10 Ft, Color: White
I bought this for my fiancee at the time who had several things to plug in, but did not have the space and would keep rotating plugs. This was able to help her organise the place better and charge multiple things at once. She absolutely loves it.
It even has ports for phone chargers, which is very useful. The quality is very good as well. Strong and durable and looks good once you take care of it. Can blend in well and it looks good aesthetically.
