Help your VTEC breathe with Mishimoto's latest addition to our line of Honda Civic parts. This Mishimoto Civic Si induction hose replaces the accordion-style stock airbox hose with a high-quality silicone unit. The 5-layer silicone features heat-resistant embedded fibers for increased pressure and heat tolerances. Molded steel rings help to increase structural rigidity so collapsing doesn't occur when VTEC kicks in.
This Civic Si induction hose is designed to work with the stock airbox, and produce increased airflow without the need for a full aftermarket intake system. To improve airflow, these hoses feature smoothed internal dimensions to allow for maximum flow to your throttle body. This Civic Si induction hose is the perfect balance between performance gains and stock efficiency, and like all Mishimoto Honda Civic parts, they feature the Mishimoto Lifetime Warranty.

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.
