The Honda Civic Si Intercooler Kit by Mishimoto is tailor-made for those looking to enhance the performance of their 2017-2021 Honda Civic. With a sleek silver intercooler and vibrant red pipes, this kit not only boosts functionality but adds an eye-catching detail to your engine bay.

This performance intercooler kit is a must-have for turbocharged Civic enthusiasts dealing with high intake temperatures. The factory intercooler, with its tube-and-fin setup and plastic end tanks, often falls short in maintaining optimal temperatures. Mishimoto's intercooler makes a significant upgrade with an all-aluminum, bar-and-plate construction that excels at dissipating heat. By increasing the core size by 102% and fin surface area by 97%, this intercooler can reduce outlet air temperatures by as much as 20°F over stock, and up to 42°F with tuning.

Features

• All-aluminum, bar-and-plate construction
• 102% increase in core volume and 97% increase in fin surface area
• Direct-fit design with mandrel-bent aluminum piping
• 5-layer fiber-embedded silicone couplers
• Potential gains of up to 11 hp and 9 ft-lbs of torque with tuning

Our direct-fit kit overhauls the stock intercooler piping as well, swapping out the plastic and rubber for robust mandrel-bent aluminum and silicone couplers. The piping size is increased from 42mm to 55mm, allowing for improved airflow and performance. This means up to 4 hp and 8 ft-lbs of torque gain on stock tuning, with even more potential when you opt for performance tuning.
