Sard XA31461 Top Mount Intercooler Full Aluminum High-Flow Upgrade

The Sard XA31461 is a high-performance top mount intercooler (TMIC) engineered for the Subaru Impreza WRX/STi on GDA and GDB chassis platforms. Sard is a well-established Japanese performance parts manufacturer with a strong motorsport heritage, and this intercooler reflects that race-bred development philosophy.

The unit features a full aluminum construction throughout, including an enlarged intercooler core and redesigned internal flow passages and end tanks. These improvements work together to dramatically reduce intake charge air temperatures delivered by the turbocharger, helping to prevent detonation (knock) and supporting higher power outputs.

Key Features:

• Full aluminum core and end tanks for lightweight, high-efficiency heat exchange
• Enlarged core volume over the OEM intercooler for significantly improved cooling capacity
• Optimized internal and end tank design for reduced pressure drop and improved airflow
• Reduced intake charge temperatures allow denser air charge into the engine for increased horsepower
• Knock suppression through lower intake air temperatures, enabling more aggressive tuning
• Direct top mount (stock location) fitment — retains factory intercooler position for simplified installation
• Manufactured by Sard, a trusted Japanese motorsport brand with rally and circuit racing development background

The Sard XA31461 top mount intercooler is an ideal upgrade for enthusiasts seeking improved cooling performance while retaining the stock intercooler location. Its larger core and refined flow design deliver measurable intake temperature reductions, making it well-suited for modified and high-boost applications.
