Wagner Performance Intercooler Kit - Porsche 991 Turbo & Turbo S

The fatal power loss caused by intake air heat soak

When pushing through consecutive high-speed pulls or intensive track day sessions behind the wheel of your Porsche 911 Turbo, the factory intercoolers quickly reach their thermal saturation limit. By running the stock cooling hardware, the charge air compressed by your turbochargers overheats rapidly. To prevent severe engine knock, the engine control unit (ECU) immediately pulls back boost pressure and retards ignition timing. Without this heavy-duty Wagner Porsche 991 intercooler kit, you accept a sudden loss of dozens of horsepower exactly when demanding peak performance from your race car.

A heat-soaked cooling setup causes a visible drop in top-end torque and increases thermal stress on your turbochargers. By neglecting the quality of your charge air cooler, you restrict your engine's volumetric efficiency and lose the pure, unadulterated acceleration typical of German supercars.

Advanced engineering for maximum airflow and thermal efficiency

This high-performance intercooler kit features free-flowing, CAD-optimized cast aluminum end tanks designed to eliminate internal air turbulence. Equipped with a custom-engineered high-efficiency core, it significantly drops backpressure compared to factory restrictions. This makes it the absolute foundation for engine customization if you are aiming for a reliable Stage 1, Stage 2, or customized big-turbo build on your sports chassis.
