Nissens 06E-145-621S Supercharger Charge Air Cooler / Intercooler

The Nissens 06E-145-621S is a direct-fit OE-replacement supercharger intercooler (charge air cooler) engineered to meet or exceed original equipment specifications for Audi, Volkswagen, and Porsche 3.0T supercharged applications. Mounted internally within the supercharger assembly, this water-cooled charge air cooler reduces the temperature of compressed intake air before it enters the engine, increasing air density for more efficient combustion and optimal performance.

Key Features:

• Water-cooled design with brazed aluminum cooling fins for maximum thermal efficiency
• Turbulator tubes for improved airflow and increased heat exchange surface area
• Compact louvered fin construction maximizes heat transfer within a tight package
• Specially designed core end plates minimize mechanical stress to reduce the risk of failure
• Reinforced plastic tanks enriched with 30–35% fiberglass content; no recycled plastics used
• Straight left and right connectors without quick coupling — matches OE configuration
• Aluminum construction with brazed cooling fins for durability and corrosion resistance
• Core depth: 61 mm | Core length: 69 mm | Core width: 260 mm
