The APR Coolant Performance System (CPS) is a massive front-mounted cooler upgrade that dramatically reduces intake air temperature (IAT), minimises heat soak, and provides increased performance! It is 140% larger than stock 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!

Quick Facts:

• Dramatically lowers intake air temp (IAT)
  Increases and retains HP while minimizing power-robbing heat soak!
• Massive frontal surface area (core) and volume (radiator)
  29″ x 05.5″ x 2.1″ – 159.5″² & 054″³ – OEM
  22″ x 17.4″ x 1.7″ – 382.8″² & 130″³ – APR
• Highly effective dual-pass core design
  Tightly packed external louvered fins rapidly dissipate heat as coolant flows through internal cooling paths.
• Self-bleeding and self-optimizing system
  Air-bubbles trapped within the system kills performance! The self-bleeding system constantly removes air from the system, without any manual intervention!
• Retains factory safety and control
  The ECU retains full control over the system, protecting against pump failure and coolant leaks.
• Easy to install and maintain
  All the performance without the headaches. Each system is fully pressure tested after assembly.

The APR Ultracharger System dramatically increases horsepower and torque, and maximises 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-aluminium 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 Restriction

The factory throttle body is a massive power-robbing restriction. Its cross-sectional area is ~25% smaller than the supercharger’s inlet, causing airflow to plummet at high supercharger speeds. It’s responsible for losses as high as 33 HP!

The Solution

The APR Ultracharger Throttle Body is huge. Its cross-sectional area is ~28% larger than stock, and an additional 5% larger than the supercharger’s inlet. It completely eliminates the throttle body as a point of restriction and allows for maximum airflow into the supercharger.

The APR Ultracharger ECU Upgrade

APR’s incredible Ultracharger ECU Upgrade is why it all just works. It delivers an outstanding driving experience, packed with a smooth daily driving, thrilling wide open throttle acceleration, and unmatched performance. It’s our most advanced 3.0 TFSI software to-date, and it’s included as a free upgrade to all who own an APR Stage II ECU Upgrade.

APR’s Ultracharger ECU Upgrade is required. This included upgrade requires purchase of APR’s Stage I and Stage II ECU Upgrades.
