Top Mods to Max Out Your Audi B9/B9.5 S4’s Performance at ORT Motorsport

Your Audi B9/B9.5 S4 is already a high-performance vehicle, but with the right upgrades, it can become a true powerhouse. Whether you’re looking to increase horsepower, sharpen handling, or add a more aggressive exhaust note, ORT Motorsport has all the performance parts and expertise you need to take your S4 to the next level. Here are the best mods to unlock your car’s full potential.


ECU Tune


The ECU tune is the most effective and cost-efficient way to boost your S4's performance. By optimizing your engine’s parameters—such as boost levels, fuel mapping, and ignition timing—a custom ECU tune will deliver noticeable increases in horsepower and torque. Your car will feel livelier and more responsive, whether you're cruising on the highway or pushing it hard on a winding road. For DSG or automatic-equipped S4s, adding a TCU tune will further enhance performance with faster, more precise gear shifts, making every drive smoother and more exciting.


Intake, Turbo Inlet & Intercooler


A performance cold air intake, turbo inlet, and upgraded intercooler are essential mods to increase airflow and reduce intake temperatures. A cold air intake allows your engine to inhale cooler, denser air, while the turbo inlet ensures smoother airflow to the turbocharger, improving spool time and efficiency. The intercooler plays a vital role in lowering air intake temperatures, which leads to more consistent power delivery, especially under heavy throttle or in hot conditions. Together, these upgrades create a more responsive, powerful engine, delivering increased performance for both street and track driving.


Exhaust System


Give your S4 a more aggressive tone and enhanced performance with a performance exhaust system. Upgrading the exhaust reduces backpressure, allowing the engine to breathe more freely and deliver additional horsepower. But it’s not just about power—replacing the stock exhaust with a performance system also gives your S4 a sportier, more refined sound that complements its aggressive looks. Whether you're opting for a cat-back system or a sportier muffler, a new exhaust will turn your S4 into a true road warrior that sounds as good as it performs.


Suspension: Rear Sway Bar & End Links


To handle all that extra power, you need to upgrade your suspension. Installing a rear sway bar and upgraded end links will drastically improve your S4’s cornering ability by reducing body roll and improving overall stability. These mods allow your car to stay flatter through corners, providing more confidence and control when pushing your limits. The rear sway bar stiffens the rear suspension, and the end links ensure everything stays tight, giving you sharper, more responsive handling. Whether you’re carving through tight turns or pushing through high-speed corners, these suspension upgrades are crucial for a truly track-ready experience.


Brakes


When upgrading performance, don’t forget about stopping power. After all, there’s no point in adding horsepower if you can’t safely slow down when needed. Upgrading your brakes is essential to match the increased power of your S4. Start with ceramic brake pads, which offer better heat resistance and reduced brake dust. For enhanced braking performance, consider slotted or drilled rotors that improve cooling and help prevent brake fade during hard driving. For ultimate stopping power, a big brake kit with larger rotors and upgraded calipers will ensure your S4 can handle any challenge, whether you’re on the street or at the track.
