Introduction to the AWE Tuning 2.7T Cold Air Intake

The AWE Tuning 2.7T Cold Air Intake has become a go-to upgrade for owners of the Audi 2.7-liter biturbo engine, found in models like the B5 S4, B5 A6 2.7T, and the Allroad. This intake system is engineered to replace the restrictive factory airbox and ducting, allowing the turbos to breathe more freely. For enthusiasts seeking a noticeable improvement in throttle response, turbo spool sound, and modest horsepower gains, the AWE Tuning intake offers a well-engineered solution.

Unlike generic cold air intakes that often rely on heat-soaked open filters, AWE designed their 2.7T system to draw cool air from the front bumper area, preserving intake air density. The kit includes a high-flow cotton filter, mandrel-bent aluminum intake pipes, silicone couplers, and all necessary hardware. In this expanded guide, we cover dyno-verified power gains, total cost of ownership, installation tips, and long-term maintenance so you can decide if this intake belongs in your engine bay.

Dyno-Verified Power Gains

One of the primary reasons owners invest in a cold air intake is the promise of extra horsepower. The AWE Tuning 2.7T Cold Air Intake consistently delivers gains in the range of 10 to 15 wheel horsepower and similar torque improvements on a basically stock engine. Independent dyno charts posted on enthusiast forums such as Audizine show a peak gain of 12 hp and 14 lb-ft of torque when swapping from the stock airbox to the AWE system.

Horsepower and Torque Curve Improvements

The factory intake on the 2.7T is known for its restrictive snorkel and small airbox inlet, which creates a bottleneck at higher RPMs. By opening up the intake path, the AWE system allows the turbos to spool more rapidly, shifting the torque curve earlier. Owners report feeling a stronger pull between 3,000 and 5,500 RPM, and the engine revs more freely to redline. The gains become even more pronounced when combined with a stage 1 or stage 2 software tune, often adding another 5–8 horsepower on top of the intake’s standalone gains.

Throttle Response and Turbo Spool

Beyond peak numbers, the most praised performance benefit is improved throttle response. The lightweight aluminum intake pipes reduce the volume of air to be pressurized, making the engine feel sharper. Combined with the louder induction noise, the driver gets a more immediate sensation of acceleration. This improvement alone makes the AWE intake worthwhile for many enthusiasts who prioritize driving feel over peak dyno figures.

Cost Breakdown and Value

The AWE Tuning 2.7T Cold Air Intake sits in the premium segment of aftermarket intakes, with a typical retail price between $350 and $400. While it is more expensive than some no-name alternatives, the build quality, fitment, and included AWE warranty justify the cost for most buyers. Below is a detailed cost analysis:

  • Intake Kit (Direct from AWE or Retailers like ECS Tuning, FCP Euro): $380 (average price as of 2025).
  • Shipping: Usually $15–$25 for ground delivery.
  • Professional Installation: $100–$150 if you are not comfortable doing it yourself.
  • Optional Filter Cleaning Kit: $20–$30 (reusable every 30,000 miles).

Note: Prices may vary based on promotions and retailer. Check AWE Tuning’s official website for the latest pricing.

Comparison with Competitors

Other intakes for the 2.7T, such as the FE Service Race Intake or K&N Typhoon, are priced lower (around $200–$300), but they often lack the enclosed airbox design that prevents heat soak. The AWE system includes a heat shield and directs air from the factory cold air feed, keeping intake temperatures lower during sustained driving. For those living in warmer climates or who track their cars, the extra $100 investment in the AWE intake pays for itself through consistent power delivery.

Installation Experience

Installing the AWE Tuning 2.7T Cold Air Intake is a moderately straightforward job for a weekend DIYer. Most owners complete the swap in 1.5 to 2.5 hours with basic hand tools. Below we provide a comprehensive step-by-step guide, including tips to avoid common frustrations.

Tools and Supplies Needed

  • 10mm, 12mm, and 13mm sockets with ratchet and extensions
  • Flathead and Phillips screwdrivers
  • Trim removal tool (optional, for plastic clips)
  • T25 Torx bit (for some engine cover bolts)
  • Torque wrench (for tightening clamps to spec)
  • Shop rags and brake cleaner (for cleaning intake ports)
  • Thread locker (blue Loctite recommended for metal-to-metal connections)

Step-by-Step Installation

  1. Disconnect the Battery: Always start with the negative terminal disconnected to avoid any electrical shorts and to reset the ECU adaptation for the new airflow.
  2. Remove the Engine Cover: Take off the plastic engine cover (if equipped) by pulling straight up. On some models, you may need to unclip the oil filler neck extension.
  3. Remove Stock Airbox: Loosen the hose clamp connecting the intake tube to the turbos. Disconnect the MAF sensor electrical connector. Unclip the airbox from its mounting points and lift it out along with the intake snorkel.
  4. Clean and Inspect: Use a shop rag and brake cleaner to wipe away any oil or debris from the throttle body inlet and the turbo inlet pipes. This prevents contaminants from entering your engine after the new intake is installed.
  5. Install the AWE Heat Shield and Pipes: Position the supplied aluminum heat shield in the former airbox location. Attach the intake pipes using the silicone couplers. AWE includes a bracket to secure the pipe to the factory mounting point; tighten these with thread locker.
  6. Mount the Filter and Enclosure: Slide the high-flow cotton filter onto the intake pipe inside the heat shield. Reinstall the factory cold air snorkel that routes air from the grille area to the intake. Ensure the rubber seal between the snorkel and heat shield is snug to prevent hot engine air from being drawn in.
  7. Connect the MAF Sensor: If the intake requires transferring the MAF sensor, carefully remove it from the stock housing and install it into the AWE intake pipe. Reconnect the wiring harness.
  8. Double-Check Clamps: Tighten all hose clamps using a torque wrench to 4–5 Nm (or tighten until snug, avoiding over-tightening that could cut silicone).
  9. Start the Engine: Reconnect the battery, start the engine, and let it idle for 30 seconds. Check for any vacuum leaks (hissing sounds) and verify that the intake is drawing air quietly. Rev the engine gently to confirm smooth operation.

Common Installation Pitfalls

  • MAF sensor orientation: Ensure the sensor arrow points in the direction of airflow. Reversing it can cause a check engine light and poor running.
  • Snorkel clearance: Some aftermarket intercooler pipes may crowd the intake snorl; carefully position the couplers to avoid rubbing.
  • Filter oiling: If you serviced the filter before installation, wait 24 hours for the oil to wick completely to avoid MAF contamination.

Sound and Driving Experience

Many buyers choose the AWE intake for the auditory excitement it brings. The factory intake muffles the induction noise, but with the AWE system you can clearly hear the turbos spooling, the blow-off valve recirculation, and a deeper intake growl as RPMs climb. The sound is not obnoxious at cruising speeds—most owners report minimal drone—but under full throttle, the car sounds genuinely aggressive. This enhanced NVH (noise, vibration, harshness) is often cited as a key part of the enjoyment.

For daily driving, the intake is comfortable: highway cruising is quiet enough for long trips, yet quick blips of the throttle produce a satisfying whoosh from the engine bay. The increased intake sound also helps you gauge engine load and turbo boost pressure without needing a gauge.

Compatibility and Maintenance

Vehicle Fitment

The AWE Tuning 2.7T Cold Air Intake is designed to fit:

  • Audi B5 S4 (2000–2002)
  • Audi C5 A6 2.7T (1999–2003)
  • Audi C5 Allroad 2.7T (2001–2005)

It is not compatible with manual transmission cars that have a larger clutch slave cylinder without some modification, but AWE includes a spacer kit for such cases. Check your specific year and transmission before ordering. For the most current fitment list, see AWE’s product page.

Filter Maintenance

The cotton gauze filter is reusable. Clean it every 30,000 miles with a dedicated filter cleaning kit. Over-oiling can damage the MAF sensor, so apply oil sparingly and allow the filter to rest for 2–4 hours before reinstallation. K&N offers a popular cleaning kit, but any high-quality kit works.

Long-Term Reliability

Owners who have run the AWE intake for 50,000+ miles report no negative effects on engine longevity. The aluminum pipes are resistant to cracking, and the silicone couplers hold up well against engine bay heat. The heat shield design prevents major heat soak, so intake air temperatures remain within a healthy range even during summer driving. Replacing the filter every 30,000 miles and periodically checking clamp tightness is all that is needed.
