Construction & Design

The Mishimoto SL Cooler intercooler is built with robust cast aluminum end tanks that resist cracking and warping under high boost pressures. Its dense bar-and-plate core maximizes surface area for heat dissipation while maintaining structural integrity during extended heavy-duty use. This ensures consistent cooling performance even in the most demanding environments.

Silicone boots incorporate Mishimoto’s proprietary DuraCore™ technology, providing enhanced durability against heat, pressure, and chemical exposure such as fuel and oil. The intercooler’s finishes—available in silver or black—are precision-applied to resist corrosion and maintain a clean, professional look over time.
