Offering a 2.0L TFSI engine with the latest technology and performance, the B9 A4 is now known to enthusiasts as the best A4 ever manufactured. With every vehicle and engine platform, there can always be improvements.
#1 Catback Exhaust System
IPE Valvetronic exhaust system provides an immensely loud exhaust tone while having the option to be discrete and quiet all in one package. Constructed of the highest-quality stainless steel, IPE brings elegance and aggression to the table with this exhaust system. Seamlessly installing and offering a snug fit similar to OE provides a pleasant installation and driving experience. Using valving within the exhaust piping, the driver can discretely drive around without causing a nuisance.
At a simple push of a button, the exhaust is opened up unlocking embellishments like pops and bangs which are typically muffled off with the valve closed. Being able to hear the exhaust during a spirited drive through the canyons is quite the experience, and is easily obtainable thanks to the IPE Valvetronic exhaust. Once you get back to the city the valves can be closed off giving no indication of hard-driving or modifications even being done to the car making this ideal for those pursuing a sleeper build.
The increase in piping diameter offers immense power gains along with torque. Being that the mufflers offer the right amount of restriction, they permit an increase of throttle response in lower RPMs. With the valves closed off, the same amount of performance can be experienced thanks to the overall elimination of restriction. Generating higher airflow was achieved thanks to the mandrel-bent construction that offers smooth transitions for the exhaust to travel through without turbulence.
Overall, the IPE Valvetronic exhaust system features great benefits to performance, style, and tonality giving the B9 A4 an aggressive timbre while truly increasing the horsepower and torque. The construction provides trouble-free installation and sturdy mounting as it utilizes the factory exhaust hangers for a precision fitment.
AWE Tuning caters to the enthusiasts that want the most customization out of their exhaust system. Featuring Touring, Switch Path, and Track Edition exhaust systems, AWE offers owners the best buying experience when it comes to fine-tuning their exhaust for exactly what they need. Comprised of high-quality stainless steel, AWE only brings the best of the best to the table for each exhaust they manufacture and the B9 A4 was no exception.
For those that seek a mellow exhaust that won’t scare Grandma on your Sunday drive, the Touring Edition exhaust is the perfect solution. Achieving performance gains from the touring exhaust is easily obtainable as the mufflers offer plenty of noise suppression along while increasing the airflow.

Being that many owners have different purposes for their B9 A4, AWE Tuning answers to any motorsport use and precision-engineered each exhaust with mandrel-bent tubing and high-quality stainless steel construction.
#2 Cold Air Intake System
Feeding the engine the coldest air possible is what ultimately will increase horsepower. Simply replacing the factory intake system is not the only purpose of cold air intakes. The benefit of installing a cold air intake is allowing the engine to ingest the coldest and most dense oxygen possible for ultimate power increase. Manufacturers have different techniques to bring the intake air temperature down (IAT).
CTS Turbo developed one of the best intake systems for the B9 A4 thanks to its incorporation of the factory air scoop. Offering a simple installation is achieved with the silicone tubing and precision fitment which shows the level of detail put into the intake. A heat shield is included to reduce IAT due to the engine bay naturally emitting heat. The shield prevents the surrounding hot air from impeding the IAT which can result in a lack of power.
Featuring a six-inch velocity air filter and 3.5-inch tubing, the CTS intake system features additional benefits other than replacing the intake. The air filter features a convex design at the top of the cone which increases air volume and velocity when entering the intake. Being that the intake ties into the factory scoop, nothing but the coldest air is being directed toward the air since the scoop feeds from the front of the vehicle.
With a simple construction and flawless engineering, the CTS Turbo intake system is the perfect solution for B9 A4 owners. Increasing the power output by 10-12 horsepower with a stock setup is a phenomenal step. When paired with tuning, the efficiency of the intake is maximized and capitalizes on the improved throttle response achieved with the CTS intake.
AWE Tuning engineered the AirGate carbon fiber intake to increase aesthetics along with performance while enhancing the natural sound of the induction into the turbocharger. The carbon fiber construction offers a significant reduction in IAT due to the dispersion of heat through the fibers compared to a solid aluminum tube like most competitors.
Adding a sense of style is achieved upon the installation of the AWE AirGate intake system thanks to the gloss finish to enhance the 2×2 carbon fiber. The increased performance was permitted with the incorporation of a lid and routing the air to the very front of the vehicle for optimal IAT. Reducing the IAT translates to higher power output and overall feel. An aggressive induction growl along with turbo spool can be heard after installing the intake due to the increase in airflow throughout the whole intake.
The air filter provided with the AirGate intake system offers exceptional filtration without restricting the airflow. Accessing the filter is as easy as removing two hex screws to reveal the filter tucked away ready for cleaning. Perfect fitment and no check engine light guarantee is extended from AWE Tuning to prove the excellence of the AirGate intake system.
Designed, engineered, and tested in-house provides the highest quality product delivered to the customer. This makes for a fantastic buying experience while offering maximum performance gains and increasing the overall experience thanks to the 12HP and 9 lbs/ft increase. For increased air volume and power, the lid can be removed without altering the rest of the intake which gives owners even more flow.
#3 VR Tuned ECU Flash
When it comes to gaining the ultimate performance out of your B9 A4, the VR Tuned ECU flash offers the highest amount of benefits. Bringing the power output from 252 BHP to 300BHP and an increase of 72 lbs/ft of torque from just a tune alone is incredible. The boost is increased by 40-percent which is what provides some of the extra power, but not all. Improved throttle response is achieved with the ECU tuning along with a 20% increase in fuel economy.
Giving the B9 A4 the extra power it deserves will truly transform your car, making you fall in love with it again. The additional 48HP and 72 lbs/ft is a massive step up from the factory output while improving the overall efficiency of the 2.0L TFSI. Thanks to the turbocharger, VR Tuned is able to maximize the output without sacrificing longevity, durability, or fuel economy thanks to the help of the turbo.
Simply plugging into the factory OBD-II connector under the dash with one of our provided modules, or mail-in your ECU to have it bench flashed. A tune is highly beneficial to a turbocharged vehicle compared to naturally-aspirated vehicles due to the boost pressure being able to be raised. Raising the boost pressure permits power gains in the lower RPMs while the throttle response improvement offers a slight increase to torque. With bottom and top end both enhanced, the VR Tuned ECU flash makes for the perfect addition to your B9 A4.
If modifications are already done to the B9 A4 without a tune, they are virtually useless since they are not being utilized at full capacity. The VR Tuned ECU flash optimizes the performance of each modification and increases the power even higher with aftermarket components installed. The VR Tuned ECU flash will adjust the tune automatically when any aftermarket parts are installed. Fuel mapping is adjusted when different octane fuel is used, as well. Each aftermarket component offers additional benefits when the VR Tuned ECU tuning has been implemented.
KW Suspension has developed some of the most prestigious coilovers for the B9 A4. Track tuning and street testing provide an immaculate product that will last many track sessions. The importance of a coilover designed specifically for the B9 A4 is the valving inside. Being that KW Suspensions has been in business since 1995 focusing on German tuning, they know a thing or two about suspension dynamics.
Each series from KW Suspensions is tested on Germany’s country roads, long straights on the autobahn, and even at the Nurburgring.

KW Suspensions also offer an additional module to cancel out the error code with the ECU since the factory electronic damping system is eliminated with the Variant Series.
For owners that wish to retain the factory damping control, KW Suspensions offers their height-adjustable spring (H.A.S.) lowering kits. The H.A.S. kits allow the function of the factory electronic damping control to remain intact. Lowering the center of gravity is a massive gain for any vehicle when it comes to handling. The H.A.S. lowering kit is the ideal solution for the daily driver B9 A4 that still needs a little extra style and handling.
Simply installing a set of wheels on your car can truly transform the whole vehicle. Being that the B9 A4 came with 18-inch wheels from the factory, many owners opt to go with an inch or two larger when purchasing their wheels. The larger wheel size fills in the factory wheel arches which give the B9 A4 a much more aggressive stance and presence.
Volk Racing is widely known as one of the most popular performance wheel manufacturers. There is a reason you will always find a set of Volk Racing wheels on the track. Being such a lightweight and versatile wheel is what makes Volk Racing so unique.
