If you follow our engineering blog you may have noticed some recent attention on the 8th-generation Civic Si. Well, we aren't making a push for just this generation. We also want to dive into the 9th-generation and develop some unique new parts to improve this awesome car.
Our first project will be quite simple: to produce a Civic Si induction hose that replaces the stock rubber unit. This upgrade provides improved durability as well as pleasing aesthetics for those seeking some engine bay style. We have seen slight power increases with intake hoses developed in the past, so we will be dyno testing our component to bust any myths around power gains.

The stock intake hose is somewhat similar to the 8th-generation piece, but the shape differs slightly and there is one less CCV port on the 9th-generation hose.
As with our 8th-generation unit, we will be creating a smoother silicone piece to provide unrestricted airflow in this portion of
