Keep charge air temperatures down in your turbocharged Civic with the Mishimoto Performance Intercooler Kit. The stock intercooler uses tube-and-fin construction with plastic end tanks — a perfect breeding ground for high temperatures. Mishimoto's design eliminates the heat soak that sets up shop in the stock unit.

The all-aluminum, bar-and-plate construction is built to shrug off the heat generated from compressing air into the intake manifold. Core volume increases by 102% and fin surface area by 97%, dropping outlet air temperatures by 20°F over stock — up to 42°F with a performance tune.

The upgrade doesn't stop at the core. This direct-fit kit also overhauls the stock intercooler piping, replacing the plastic and rubber combination with mandrel-bent aluminum and 5-layer fiber-embedded silicone couplers. Piping increases from 42mm to 55mm on both the hot and cold sides — a 30% size increase — with reduced bend angles for more direct airflow through the system.
