The Competition Intercooler Kit is a high-volume upgrade designed to improve charge-air cooling efficiency on the Audi 3.0 TFSI platform. Compared to the factory intercooler core, it increases both core volume and flow area to support lower intake temperatures with minimal backpressure.

Key features

• Tube Fin core with internal turbulators for efficient heat transfer
• Cast aluminum end tanks developed using CFD flow analysis
• Anti-corrosion coating with good thermal conductivity
• Pressure tested and stable up to 6 bar
• Approx. weight: 9.5 kg
• Direct replacement (plug-and-play style installation)
• Suitable for motorsport use (per manufacturer)

Optional charge-air piping (kit variant)

• Three reinforced silicone hoses
• One aluminum charge-air tube
