Product Description

The Mishimoto MMINT-CIV-16BK intercooler is a direct-fit performance upgrade designed for 2016-2021 Honda Civic models equipped with the 1.5 L turbo engine and for 2017-2020 Civic Si variants. Featuring a robust bar-and-plate aluminum core with a black finish, this intercooler increases core volume by over 100 % and expands fin surface area nearly as much compared to the stock unit, dramatically improving heat rejection and reducing intake air temperatures under boost. These improvements help reduce heat soak, support stronger charge density, and deliver up to ~3-4 whp and ~8 ft-lbs torque gains on the stock tune, with even greater potential when paired with performance intercooler piping and tuning.

The direct-fit design installs easily in the OEM intercooler location without requiring modifications to the bumper or core support, making it ideal for drivers who want increased cooling performance without complicated fabrication. It remains compatible with the factory piping layout and is protected by Mishimoto's lifetime limited warranty for long-term reliability. With up to ~42 °F reductions in outlet air temperatures in tuned applications, this intercooler is a solid upgrade for both stock and modified turbocharged Honda Civics seeking improved thermal performance and more consistent boost behavior.
