The short ram intake is designed to work perfectly with all 2016+ Honda Civic Turbo 1.5L cars, this includes Manual and CVT. Our custom velocity couplers gives you smooth transition from the intake pipe whether it is the 2.25" or 3". Flashpro or KTuner is required as we have found the cars to very sensitive to changes. This is on both the 2.25" or 3" options. Comes with MAF flange to match factory sensor and washable air filter. Note 2.25" intake uses a 2.52" filter.
