The Skunk2 Intercooler Kit for the 2016–2021 Honda Civic 1.5T is a complete bolt-on upgrade engineered to improve charge air cooling and maintain consistent performance under increased thermal load. Designed as a direct replacement for the factory intercooler system, this kit addresses the limitations of the OEM plastic-core intercooler and restrictive piping found in stock configurations.
Honda’s factory intercooler system struggles to manage heat during aggressive driving or increased boost levels, leading to elevated intake air temperatures, reduced power output, and greater risk of detonation. Skunk2’s solution replaces the factory unit with a significantly larger, fully aluminum intercooler that functions more effectively as a heat sink while flowing a greater volume of air.
The 3.5-inch thick, raw aluminum intercooler core is approximately 30% larger than stock and is paired with 2.25-inch aluminum charge piping for improved airflow and heat dissipation. Compared to the factory plastic piping, the aluminum construction resists heat soak and supports more stable intake temperatures during sustained driving.
Average intake air temperature reductions of approximately 20% help preserve power consistency and engine reliability. On an otherwise stock vehicle, gains of up to 7 horsepower have been recorded without tuning, with greater potential on modified and tuned setups.
This intercooler kit installs in the OEM mounting location and follows factory routing, requiring no cutting or chassis modifications. Included flanges allow compatibility with factory intercooler piping, and a larger coupler is supplied to accommodate upgraded throttle bodies.
