The Wagner Tuning Performance intercooler for BMW N54/N55 models—including 135i, 335i, Z4 and 1M applications—is a direct-fit replacement aimed at improving charge-air cooling for turbocharged engines. It helps reduce intake temperatures to sustain boost under load and minimize heat soak during spirited use. A vehicle-specific upgrade that installs in place of the factory intercooler for improved thermal control.
