The APR Stage III+ includes every part necessary to completely upgrade the turbocharger system. Each component is completely engineered to deliver a turn-key solution with no additional expenses required other than oil, coolant and the typical supporting modifications for these power levels such as a cat-back exhaust, intercooler and upgraded intake. Every nut, bolt, gasket, associated hardware and all turbocharger system components required for fitment and reliability are included as well. A complete step by step installation guide including recommended tools, estimated time of install and detailed pictures is supplied to each client. APR's expertly calibrated DPP ECU Upgrade specific to the Stage III+ Turbocharger System is included and is the glue that holds all of the substantial power delivery, drivability and reliability together. No other company in the world provides such a complete Turbocharger System for your TSI at these power levels.

The APR Stage III+ Upgrade includes every part necessary to completely upgrade from Stage III to Stage III+.

Representing the latest in turbocharger technology, an APR/Garrett Ballistic series turbocharger is the only choice for this premium turbocharger system. APR is unique in that we deal directly with Garrett turbochargers rather than buying turbochargers through turbocharger supply houses. Our engineering-house distributor status with Garrett turbochargers means that we receive assistance from the manufacturer on technical issues and work with Garrett engineers on specifying the optimal turbocharger for each application.

APR High Pressure Direct Injection Injectors - Approximately 30% larger than standard OEM TSI injectors.

APR's expertly recalibrated ECU Upgrade matched specifically to the Stage III+ hardware ensures flawless drivability and great power delivery. All OEM specifications for component strength is either followed or replaced by the Stage III+ hardware to ensure no premature failures of other related parts. As always, APR's included Stage III+ ECU Upgrade is equipped with EMCS technology to allow for the cruise control to be used to enable situation specific calibrations, options and advanced ECU features found nowhere else.

The Stage III+ exhaust manifold is investment cast out of Inconel, a high-temperature nickel alloy. The manifold was designed in CAD and optimized using computational fluid dynamics (CFD) software. What this means to the end user is the ultimate in performance and reliability.

APR developed a new housing that is sized according to engine displacement and maximum power output. The new cast housing allows the proper metering of the additional airflow and to minimize pressure losses. The cast aluminum housing is CNC machined to exacting tolerances and powder-coated to inhibit corrosion. A honeycomb style flow straightener is also added to prevent the MAF from seeing erroneous signals.

After the exhaust gases have left the turbocharger turbine, they flow into this stainless steel piece that directs the exhaust gases down, towards the underside of the car into the supplied exhaust downpipe.

From the cast APR exhaust downturn, the exhaust begins its travel out of the car through the three inch downpipe that is included with the Stage III+ kit.

APR uses a reinforced silicone hose to route the inlet air from the MAF housing into the compressor inlet of the turbocharger. This hose also has provisions for other connections, such as the stock crankcase vent hoses and the APR diverter valve adaptor.

This silicone hose directs air from the compressor outlet of the turbocharger to the compressor outlet pipe. The APR diverter valve adaptor also connects to this hose, as well a boost signal line for the N75 boost control valve.

APR includes a billet CNC adaptor that allows the stock diverter valve to be reused with the APR compressor inlet hose.
