GrimmSpeed 90043 Intercooler: Performance Meets Precision

If you’re a proud owner of a 2005-2009 Subaru Legacy GT or Subaru Outback XT, you already know the importance of keeping your engine’s intake air cool. The GrimmSpeed 90043 Intercooler is designed for those who demand maximum cooling efficiency and minimal airflow restriction, ensuring that your turbocharged engine performs at its best, even under high boost conditions.

Why Upgrade Your Intercooler?

As your turbocharger compresses air, it naturally heats up due to increased pressure. This heat can lead to lower air density, resulting in pre-detonation or “knock,” which can severely limit your engine's performance. While your stock top-mount intercooler (TMIC) may handle everyday driving just fine, it struggles to keep up when you push your Subaru to its limits. The GrimmSpeed 90043 is engineered to combat heat soak, allowing for sustained performance during spirited driving or track days.

Key Features

• Dimensions: 17.5in x 8.7in x 3.5in Cross Flow Core - expertly designed for optimal heat transfer and low pressure drop.
• Durability: Cast Aluminum End Tanks with a machined BPV flange for a precise fit and leak-proof seal.
• Reinforced Couplers: 5-Ply Silicone Couplers, custom molded to withstand the rigors of high-performance applications.
• Airflow Optimization: Wide-Mouth Splitter that maximizes air collection from the scoop, ensuring consistent airflow.
• Vibration Isolation: Specially designed mounting system to protect against fatigue from engine vibrations.
