The Bosphorus Innovations Interchiller Kit is an advanced cooling solution designed to combat high Intake Air Temperature (IAT) in turbocharged and supercharged vehicles by utilizing the car’s A/C system (R134a/R1234yf) to chill intercooler coolant down below ambient temperature (approaching +5°C or 0°C). Engineered for up to 500HP applications, it offers seamless compatibility with VAG (EA211 1.4 TSI, 1.5 TSI, 1.6-2.0 TDI) and BMW (B48) engines, ensuring maximum power and reliability for street or track use.
Ultra-Low Intake Temperatures: Leverages the vehicle’s refrigerant loop to drop intercooler water temperature near freezing.
500 HP Capacity: Optimized capacity for high-horsepower tuned and performance-focused setups.
Broad Engine Fitment: Direct compatibility with VAG EA211 1.4/1.5 TSI, 1.6-2.0 TDI engines and BMW B48 engines.
Eliminates Heat Soak: Prevents performance drops during extended track sessions, heavy loads, or hot climate driving.
In turbocharged or supercharged engines, compressed air heats up significantly. When this hot air enters the cylinders, engine performance drops and the risk of detonation increases. While conventional intercoolers help reduce this heat, they can become insufficient in hot climates or during extended track use.
The Bosphorus Innovations Interchiller utilizes the vehicle’s A/C system (R134a/R1234yf refrigerant) to cool the water circulating in the intercooler loop. This innovative process drops the coolant temperature well below ambient (as low as +5°C or near 0°C), resulting in drastically reduced Intake Air Temperatures (IAT), maximized combustion efficiency, and reliable peak power under extreme stress.
Key Features & Advantages
Combats Heat Soak: Maintains stable, repeatable power output even under aggressive driving and high-load conditions.
Targeted Compatibility: Custom-tailored for high-performance builds up to 500HP featuring VAG EA211 1.4/1.5 TSI, 1.6-2.0 TDI, and BMW B48 engines.
Engine Protection: Lower IAT safely suppresses engine knock, protecting internal components and ensuring long-term reliability.
