Description:

Introducing the APR Full Intake System for the Audi RS4 and RS5 (B9) 2.9T EA839APR 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 ThemselvesThe 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.

Buyer's Guide

Air Intake Buyer's Guide

An aftermarket air intake helps your engine breathe better so you can make more power. Stock intake systems are designed to balance noise, cost, and filtration rather than maximize airflow. An aftermarket intake prioritizes flow, allowing more air to reach the engine and supporting higher horsepower. This guide covers how air intakes work, what performance gains to expect, and what to verify before purchasing.

Why Upgrade Your Air Intake

Reduced Airflow Restriction: An aftermarket intake with a larger, less restrictive filter increases the volume of air your engine can draw in, directly supporting more power.
Cooler Intake Temperatures: Positioning your air filter away from hot components in your engine bay allows the engine to draw in denser, cooler air, increasing maximum power.
Improved Throttle Response: Shortening the intake path or straightening the piping can provide a more direct path for air to your engine, improving throttle response.
Induction Noise: Cone filters produce an aggressive induction sound as a byproduct of increased airflow, a characteristic many enthusiasts find as appealing as the performance gain itself.

Performance Gains

From a cold air intake alone on a naturally aspirated vehicle, expect somewhere in the range of 5–15 horsepower. Pair your intake with an exhaust, headers, and a tune, and you can see much more meaningful power improvements.

Vehicles with a turbocharger or supercharger typically see greater benefit from intake upgrades compared to naturally aspirated vehicles. This is because a turbocharger or supercharger moves a much larger volume of air than a naturally aspirated engine, so reducing intake restriction has a proportionally larger effect on the power the engine can produce.

Intake Types

Short Ram Intake

A short ram intake replaces the factory airbox with a cone filter positioned close to the throttle body, providing a short and direct path for air to reach the engine. Short ram intakes are simple, affordable, and easy to install, making them a great choice for tight engine bays and budget builds. The downside of a short ram intake is that they typically draw in warmer air, which reduces maximum power compared to a cold air intake.

Cold Air Intake

A cold air intake relocates the filter away from hot engine bay components to draw in cooler, denser air. Since cooler air contains more oxygen per volume, this supports more power. Most cold air intakes position the filter within the engine bay but away from heat sources. More serious builds will route the filter into the fender or bumper area to access the coldest possible air. Many cold air intakes include an intake box or heat shield that isolates the filter from engine heat and protects it from debris. Cold air intakes are the preferred choice when chasing maximum performance.

Snorkel

A snorkel relocates the intake point from the engine bay to near the roofline. This provides cooler air and protection against water ingestion when driving through deep water. Snorkels are most common on off-road vehicles and are rarely seen on street or performance builds.

Filter Materials

Different filter materials have different qualities and maintenance requirements. Read our Air Filter Buyer's Guide for a full breakdown.

Compatibility

Most aftermarket air intake systems are vehicle specific. Always confirm that your intake fits your specific year, make, model, and trim. If you are sourcing intake piping separately rather than buying a complete kit, plan your routing carefully before purchasing to avoid clearance issues during installation.

Conclusion

An air intake is one of the most accessible performance modifications available. It's straightforward to install, provides meaningful power improvement, and creates a strong foundation for further modifications down the line. For most builds, a cold air intake provides the best balance of performance and value. If budget or engine bay space is a constraint, consider a short ram intake which will deliver improved throttle response. Either way, pairing your intake with an exhaust system and a tune will multiply the gains well beyond what the intake delivers on its own.
