Key Features

5.5″ Thick Performance Core
The Evo 1 intercooler utilizes a 5.5″ thick core, larger than the stock unit, providing superior heat dissipation while maintaining a compact size. This design ensures a significant reduction in intake air temperature, improving engine performance by preventing heat soak during moderate driving and boosting performance during high-load conditions.

Efficient Cooling for Daily and Mildly Tuned Cars
While not as large as the Evo 2 or Evo 3, the Evo 1 still provides substantial cooling improvements over the OEM intercooler, making it ideal for stock or mildly tuned vehicles. It enhances overall engine efficiency, ensuring that intake air stays cooler for longer, even under spirited driving conditions.

Improved Turbo Performance and Throttle Response
With lower intake air temperatures, the Evo 1 provides denser air for combustion, improving turbo response, throttle control, and power delivery. This leads to smoother acceleration, better mid-range torque, and more consistent performance, particularly for daily-driving and mild tuning applications.

Durable, Lightweight Design
Crafted from high-quality aluminum and featuring TIG-welded seams, the Evo 1 intercooler is designed for strength, longevity, and thermal stability. It is built to withstand the heat and pressure commonly encountered in both daily driving and moderate performance applications.

Direct-Fit Installation
The Evo 1 intercooler offers a direct, bolt-on installation with no modification required. It uses the factory mounting points and connections, making it an easy upgrade for anyone looking to improve cooling efficiency without additional customization or hassle.
