APR

The APR Ultracharger System dramatically increases horsepower and torque, and maximizes the power potential of the 3.0 TFSI. It removes a massive pre-supercharger restriction, allowing uninterrupted airflow into the supercharger for up to an astonishing 542 HP with APR’s Supercharger and Crank Pulleys. Stunning carbon fiber and smooth cast-aluminum adorn the system, creating a clean and simple install that looks just as powerful as it is. Finally, APR’s innovative Ultracharger ECU Upgrade delivers a smooth and exciting driving experience, and it is included as a free upgrade to all who own an APR Stage II ECU Upgrade.

The APR DQ250 Clutch Packs replace the factory transmission’s friction disc and steel plates with an advanced and proprietary design that allows for greater performance. The system goes beyond the norm of simply increasing the disc and plate count, and takes a multi-step approach that not only greatly improves the overall friction engagement area, but does so without sacrificing the total heat-sink material mass of the steel plate. With 40-50% more friction discs, tighter tolerances, carefully specified materials, surface finishes, a proprietary top plate design and more, the clutches hold more torque, prevent premature failure, and provide quick shudder-free high-performance engagement!

The APR R1 Diverter Valve is a critical performance upgrade recommended at all stages of performance as it replaces the failure prone factory unit. The R1 is designed withstand extreme boost pressures at the highest levels of performance, while offering lightning fast response thanks to the unit’s friction-free diaphragm-based design. Unlike piston based units that can stick and bind in the winter, the APR R1 is virtually maintenance free, requiring no greasing or o-ring replacements, as is common with other units. Constructed from CNC-machined billet-aluminum with a high-temperature Nomex-reinforced diaphragm, the R1 is designed to be the last DV upgrade the engine will ever need!

The APR Turbo Inlet Pipe is an easy-to-install bolt-on upgrade that eliminates a restriction before the turbocharger. Unlike fabricated units on the market today, ours is cast from aluminum, allowing for an organically shaped inlet that transitions gradually over a large distance. Such a design promotes better flow rather than abruptly reducing at the turbocharger’s inlet like other units. It’s larger than stock throughout, removes a large internal restriction at the PCV inlet, and outflows the factory unit allowing the turbocharger to operate more efficiently. We fully assemble each unit with a billet securing arm, billet PCV bung and new o-ring. The inlet and outlet are CNC-machined to control tolerances and ensure snug and secure connections. This upgrade is recommended at all stages utilizing an IHI IS12, IS20 or IS38 turbocharger!

The APR Catback Exhaust System personalizes your vehicle’s looks, sound and performance. Beautifully hand-crafted T304-stainless-steel components adorn the system with stunning TIG-welding throughout. Our straight-through satin-finished mufflers are configurable to your desire, smoothing the exhaust note to a deep growl, without adding restrictions, rasp or drone. Strong high-quality bracketry and OEM-style clamps hold the system steadily in place, making the install or removal a snap, and fitment simple, yet precise. A cast 3” to dual 2.5” rear splitter creates an ultra-smooth transition, steadily feeding exhaust gasses out of the system, while looking tidy from under the rear bumper. Finally, removable 4" satin-finished slash-cut exhaust tips finish the system, adding a classy motorsport-inspired touch to the rear of the vehicle.

The APR Coolant Performance System (CPS) is a massive front-mounted cooler upgrade that dramatically reduces intake air temperature (IAT), minimizes heat soak, and provides increased performance! It is 140% larger than the stock B8 unit and features a self-bleeding cooling circuit to ensure it is always operating at peak performance. The system is easy to maintain and fully integrated into the factory cooling circuit. This upgrade is highly recommended at every stage!
