Help the air flow through the intercooling system of your L15B7 with the Mishimoto Performance Intercooler Pipe Kit for your 2016-2021 Honda Civic 1.5T or 2017-2020 Civic Si! The stock equipment on your Honda Civic is riddled with bends, and is constructed from degradation-prone materials at a restrictive diameter. All of these are characteristics that will limit the potential of your turbo-Civic. We here at Mishimoto want to remove the restriction on the future potential of the L15B7. We started with the size of the pipes. We added 13mm overall to both sides of the piping system bumping the diameters from 42mm to 55mm, equating in a 30-percent increase in size. We also took the liberty of reducing the angles of the bends in the piping, giving the charged air a more direct flow through the intercooling system improving the flow. The size and direction of the piping wasn't the only change either. Gone is the degradation-prone plastic that makes up the cold-side piping, which has been replaced with a section of mandrel-bent aluminum pipe, giving your intercooler pipe kit an improvement in durability and style. We also took the liberty to replace the rubber in the stock kit with couplers constructed with 5 layers of durable silicone embedded with heat resistant fibers, keeping engine heat out of your intercooled charged air. The result of adding the Mishimoto Intercooler Pipe kit to you 2016-2021 Honda Civic 1.5T or 2017-2020 Civic Si is the addition of flow through your intercooling system, along with a few extra horses under the hood, with the potential for more with a tune. The 2016-2021 Honda Civic 1.5T Mishimoto Performance Intercooler Pipe Kit is available in wrinkle black and Rallye red, and includes the Mishimoto lifetime Warranty.
