Unitronic Intercooler Upgrade - 2.5 TFSI EVO

Designed specifically for vehicles equipped with the 2.5 TFSI EVO engine, the Unitronic Intercooler Upgrade is a direct OEM replacement engineered to dramatically improve charge-air cooling efficiency and reduce heat soak under aggressive driving conditions.

Efficient Cooling for Maximized Power

When intake air temperatures reach a critical threshold, the engine control unit compensates to protect the engine, resulting in reduced performance. Unitronic’s oversized intercooler core measures 24" x 10.2" x 3.54" (610mm x 260mm x 90mm), representing a 71% increase in volume compared to the factory intercooler.

This significant increase in core volume allows for greater heat exchange, resulting in lower intake air temperatures and more consistent power output during repeated high-load driving.

Core Construction & Specifications

• High-efficiency bar-and-plate intercooler design
• Cast aluminum core and end tanks
• TIG-welded construction for durability
• Black finish for an OEM+ appearance
• 71% larger core volume compared to OEM

Proven Results

Unitronic conducted stress testing using six consecutive dyno pulls, with a 20-second pull followed by a 30-second cool-down period between runs. Intake air temperatures were recorded for both the OEM intercooler and the Unitronic intercooler under identical conditions.

The Unitronic Intercooler demonstrated a significant reduction in intake air temperatures compared to stock, resulting in cooler, denser air entering the engine and improved resistance to heat soak.

Unbeatable Design & Construction

Development begins with detailed performance and efficiency goals. Unitronic uses 3D scanning technology to digitally capture the factory engine bay and OEM components. Engineers then design the intercooler to ensure proper clearances, optimized airflow, and seamless integration within the factory envelope.

This process ensures optimal fitment, maximum cooling efficiency, and reliable performance without compromising other components.

Advanced EFD Capabilities

Using advanced flow development techniques, Unitronic optimizes internal airflow through the intercooler core and end tanks. This ensures even air distribution, minimized pressure drop, and improved thermal efficiency across the entire core surface.

Precisely Manufactured for Direct Bolt-On Fitment

This intercooler is designed as a true bolt-on replacement utilizing factory mounting points. No cutting, trimming, or modification to the bumper, crash bar, or radiator support is required.
