CSF 04-13 BMW 335i/xi (E90/E91/E92/E93) High Performance Stepped Core Bar/Plate Intercooler - Silver

The rounded front face of this CSF intercooler's cooling bars is a notable design choice. Unlike flat bars that scatter airflow, these rounded bars guide air smoothly into the core, improving how efficiently it cools the intake charge. This stepped core design, with a larger bottom section that's 5.5 inches thick and a massive 8.25-inch tall front face, significantly increases both surface area and internal volume compared to the stock unit.

This intercooler is designed to be a direct fit for a range of BMW models, including the 135i, 335i, and Z4, meaning it installs using the factory mounting locations and BMW-style quick-connect fittings, so no cutting or trimming is required. It's built to handle substantial power increases, easily managing over 1000 horsepower, making it a solid option for owners pushing their N54 or N55 engines well beyond stock performance levels. The silver finish gives it a clean look under the hood.
