Beat the heat in your turbocharged Honda Civic with Mishimoto's top - notch performance intercooler kit! As turbochargers become the norm, Honda's tenth - gen Civic with the L15B7 engine faces the age - old heat problem. The stock intercooler, with its tube - and - fin design and plastic end tanks, is a hotbed for high temperatures. Our all - aluminum, bar - and - plate intercooler is a game - changer. It's built for Honda enthusiasts, slashing high charged air temperatures. With a 102% increase in volume and a 97% boost in fin surface area, it drops outlet air temperatures by 20°F compared to the stock one, and up to 42°F with a performance tune. The benefits don't stop at the intercooler. Our direct - fit kit overhauls the stock piping. We swapped the plastic and rubber for mandrel - bent aluminum and 5 - layer, fiber - embedded silicone couplers. The piping size increases from 42mm to 55mm, a 30% growth, and the reduced bends ensure a smoother air flow. On stock tuning, it adds up to 4 hp and 8 ft - lbs of torque, and with a tune, you can get up to 11 hp and 9 ft - lbs of torque. This part fits a wide range of 2016 - 2021 Honda Civic models, including EX, EX - L, Si, Type R, and more.

Using this Mishimoto intercooler kit is straightforward. First, make sure your car engine is cool. Then, remove the stock intercooler and its piping following your car's manual. Install the new intercooler in place, aligning it properly. Connect the mandrel - bent aluminum pipes with the 5 - layer silicone couplers carefully. When tightening the connections, don't over - tighten as it may damage the parts. For maintenance, check the intercooler and piping regularly for any signs of damage, like cracks or leaks. Clean the intercooler with a soft brush and mild detergent every few months to keep it working efficiently. If you notice any decrease in performance or an unusual increase in temperature, it's a good idea to have it checked by a professional. Remember, always follow local laws and regulations when making modifications to your vehicle.
