Two NEW items from APR!

Posted on November 18, 2010 – 12:59 pm

We are very excited to share the release of two new items from APR!
Audi (B8) A4 & A5 2.0T Carbonio Intake System!

Carbonio’s latest carbon fiber intake for the 2.0 TFSI & 1.8 TFSI engine is a ram air design that completely seperates the intake filter from the engine bay. Building from years of experience on and off the race track, Carbonio’s and APR’s engineering teams have spent countless hours
developing a true cold air and ram air carbon fiber design that can be recreated affordably for the street performance enthusiast.

For many years professional motorsport organizations have suffered great expense to properly tune the air intake delivery system for turbocharged engines for use in endurance and sprint races where every last horsepower and pound feet of torque can make the difference in position when crossing the finish line. Historically these designs have proven to be the most efficient and powerful although the most expensive to produce.

Aftermarket performance companies have attempted to capitalize on these designs however the cost restraints have typically resulted in compromise and deviation from the true engineering principles associated with motorsport accomplishment. Don’t be fooled by catch phrases and tag lines alluding to a new intake technology or special design characteristic. You won’t see any of these gimmicks installed on race cars at the Nurburgring.

Carbonio and APR have gone even further to maintain all oem specifications necessary to integrate cohesively with an otherwise stock engine to avoid raising eyebrows at the dealership. Flexibility was another characteristic of Carbonio’s and APR’s design whereas the new TFSI intake is also suitable for Stage 1 and Stage 2 modified engines all the way up to and beyond APR’s K04 Turbocharger System.

Constructed of aerospace grade carbon fiber and designed to remove intake restriction, APR’s Carbonio intake system provides smoother transitional airflow, increased air velocity, superior insulation of the incoming air to reduce intake air temperatures and a larger volume of available air to aid throttle response and turbocharger spool.

Ram air induction is accomplished by maintaining the oem air inlet opening at the front of the leading hood edge which is the highest pressure area of airflow across the entire vehicle. Placement of the air filter as close to this high pressure zone as possible results in overcoming some of the airflow restriction created by even the highest flow air filters available.

Benefits of the Carbonio CAI System include:

  1. Increased Horsepower and Torque
  2. Improved Throttle Response
  3. Decreased Turbo ‘Lag’
  4. Improved Fuel Economy
  5. Enhanced Engine Volumetric Efficiency
  6. Enhanced Sound of Turbo Diverter Valve
  7. Installs in an Hour (does not require bumper or headlight removal)
  8. Maintains Clean Appearance by Retaining Factory Engine Cover
  9. Maintains All Factory Emissions Components
  10. Fits Both Manual and Automatic Transmissions
  11. Fully Compatible and Complimentary with APR Software and Exhaust systems

Application Guide
Fits both B8 A4 and A5 2.0 TFSI and 1.8 TFSI.
Part Number: CI100021
Price: $449.00

Audi (B8) A4 Quad-Tip Turbo-Back & Cat-Back Exhaust System!


Reflective Sound Cancellation allows for maximum exhaust gas flow while completely eliminating in cabin sound resonance (drone). RSC™ incorporates innovative technologies developed in conjunction with NASA. With limited use of packing materials and no baffles, RSC™ allows for a completely straight and free flowing exhaust path through the RSC™ mufflers. Reflective Cancellation bounces the undesirable sound waves into each other to attenuate the wave and completely eliminate the low frequency tones that create drone. Each RSC™ muffler is tuned to eliminate specific, undesirable sound frequencies allowing only the engine’s desirable exhaust notes to be heard and improving performance.

3″ Design with High Flow Catalytic Converters

APR’s 3 inch downpipe with high flow catalyst for the A4 2.0 TFSI is the first true downpipe for the A4 and the only one that incorporates traditional exhaust performance tuning for the new 2.0 TFSI engine. Other 2.0 TFSI engine applications outside of the A4 chassis have historically enjoyed the following benefits that have never before been made available to A4 owners:

-3 inch Exhaust Tubing Diameter beginning at the Turbocharger Exit for Maximum Turbocharger Spool and Peak Horsepower

-Relocation of the Catalyst to Reduce Backpressure and Turbulent Airflow at the Turbocharger

-Incorporation of a 200 Cell Count Catalyst to aid in Turbocharger Spool and Remove Restriction

-Considerable Increases in Peak Horsepower, Peak Torque and Fuel Economy

APR is proud to offer the only true 3 inch full length downpipe available for the 2.0 TFSI A4 which delivers true exhaust Performance Without Compromise.

By utilizing a straight though design, APR is able to maximize power gains when coupled with APR’s Stage 2 ECU Upgrade without uncomfortable levels of exhaust drone while cruising.

During our development we discovered the exhaust systems flowed so well modifications to the software were absolutely required when using the new RSC systems. Spool time was significantly decreased and would result in a rather large overshoot of requested load levels which would cause the throttle to close. This can only be eliminated by properly recalibrating the engine software to match the hardware changes and APR’s Stage 2 ECU Upgrade is born.

The benefits of APR’s Stage 2 ECU Upgrade with APR’s RSC Dual Exit Full Exhaust System are as follows:

1. Turbocharger Boost Onset Reduced by Over 400 rpm’s!

2. Peak Torque is Increased by Over 100 lb ft when Compared to Stock Exhaust and Programming and by Over 70 lb ft when Compared to APR’s Stage 1 ECU Upgrade and Stock Exhaust!

3. Peak Horsepower is Increased by Over 50hp when Compared to Stock Exhaust and Programming and by 29hp when Compared to APR’s Stage 1 ECU Upgrade and Stock Exhaust!

We tested both our Dual Exit and Single Exit RSC Exhaust Systems and found the Dual Exit RSC System to deliver slightly more horsepower in the higher rpm’s as expected.

Now for the numbers as measured by APR!

Stock – 212 HP & 260 TQ

Stage 1 91 Octane – 229 HP & 323 TQ
Stage 2 91 Octane – 239 HP & 353 TQ

Stage 1 93 Octane – 234 HP & 333 TQ
Stage 2 93 Octane – 242 HP & 362 TQ

Stage 1 100 Octane – 268 HP & 338 TQ
Stage 2 100 Octane – 270 HP & 380 TQ

The most impressive aspect of APR’s Stage 1 and 2 ECU Upgrades are the gains they make over
stock at different RPM’s:

Stage 1 91 Octane – 35 HP @ 5500 RPM & 64 TQ @ 2250 RPM
Stage 2 91 Octane – 43 HP @ 2650 RPM & 86 TQ @ 2650 RPM

Stage 1 93 Octane – 40 HP @ 5500 RPM & 74 TQ @ 2250 RPM
Stage 2 93 Octane – 46 HP @ 2550 RPM & 95 TQ @ 2550 RPM

Stage 1 100 Octane – 62 HP @ 5500 RPM & 78 TQ @ 2500 RPM
Stage 2 100 Octane – 64 HP @ 5550 RPM & 114 TQ @ 2650 RPM

Dyno Performance

Please note, single exit and Dual Exit exhaust reported similar gains
