Keep the charged air temperatures down in your turbocharged Civic with the 2016-2021 Honda Civic Performance Intercooler Kit from Mishimoto! In the age of the turbocharger, Honda has finally joined the ranks of forced induction by equipping their tenth generation of the Civic with the L15B7.


Where the Earth Dreams technology might be advanced, it still suffers from an age-old enemy - heat. The stock intercooler utilizes a tube-and-fin construction coupled with plastic end tanks, giving high temperatures a perfect breeding ground. The all-aluminum, bar-and-plate construction is specifically designed to shrug off heat generated by compressing air into the intake manifold.


Mishimoto's intercooler has increased the volume by 102% and fin surface area by 97%, which helps drop outlet air temperatures by 20°F over the stock intercooler, and up to 42°F once a performance tune is added. Mishimoto's direct-fit intercooler kit also gives the stock intercooler piping an overhaul. They ditched the plastic and rubber combination that made up the original equipment and replaced them with mandrel-bent aluminum and 5-layer, fiber-embedded silicone couplers.


Mishimoto's piping also increases the size of both the hot and cold sides of the piping system from 42 mm to 55 mm, equating in a 30% increase in size. They also took the liberty of reducing the angles of the bends in the piping, giving the charged air a more direct and improved flow through the intercooling system. Mishimoto's performance intercooler kit adds up to 4 whp and 8 ft-lbs of torque on the stock tuning, with the potential to boost that power gain to 11 whp and 9 ft-lbs of torque with a tune.


The Mishimoto 2016-2021 Honda Civic Direct-fit Performance Intercooler is available in a silver or black core with the option of wrinkle black or Rallye Red piping and, as with every Mishimoto Intercooler, this intercooler includes the Mishimoto Lifetime Warranty so you can have peace of mind!!
