Untd. Performance Evo1 2.5″ Intercooler – Audi B9 – A4/A5 2.0T – S4/S5 3.0T

Description

When power demands go up, cooling needs to keep up. The Untd. Performance Evo1 2.5″ Intercooler is purpose-built to deliver cooler, denser air to your turbocharged engine—whether you’re pushing your Audi B9 2.0T or 3.0T with a tune, upgraded turbos, or just looking for a reliable performance edge. With increased core volume, optimized flow, and direct-fit engineering, this front-mount intercooler is the perfect upgrade for any enthusiast chasing consistent, repeatable performance.

Key Features:

High-Flow 2.5″ Core

The Evo1 features a robust 2.5” thick bar-and-plate core that significantly increases cooling efficiency over the restrictive factory intercooler. Designed to support higher boost levels, it reduces intake air temps, minimizes heat soak, and keeps power delivery consistent—even under back-to-back pulls or extended spirited driving.

Direct Bolt-On Fitment

Engineered specifically for the B9 platform, the Evo1 Intercooler installs with factory-style mounting points and charge pipe connections. No cutting, welding, or custom fabrication required. It’s a true plug-and-play performance upgrade.

Optimized End Tank Design

Precision TIG-welded aluminum end tanks are designed to improve airflow distribution and eliminate bottlenecks. The result is smoother, more efficient airflow from turbo to throttle body, reducing pressure drop and improving throttle response.

Proven Gains in Real-World Testing

Expect lower intake air temps, better timing stability, and consistent power delivery—especially under tuned or high-load conditions. Whether you’re running a Stage 1 or Stage 2 tune, this intercooler is built to handle it.

All-Aluminum Construction

Built from high-grade aluminum for strength and heat resistance, the Evo1 is designed to withstand the demands of high-performance driving. It’s track-tested, street-proven, and ready for abuse.

Compatibility:

• Audi A4 (B9) 2.0T

• Audi A5 (B9) 2.0T

• Audi S4 (B9) 3.0T

• Audi S5 (B9) 3.0T

(Compatible with most aftermarket charge pipe kits and tuning setups.)

If you’re serious about performance, cooling isn’t optional—it’s essential. The Untd. Performance Evo1 2.5″ Intercooler is the upgrade your B9 chassis needs to stay cool under pressure and pull harder, longer, and faster.

⚠️ Note: For maximum gains, pairing with a tune and upgraded charge pipes is recommended. Designed for high-performance and off-road use.
