Description
The Mishimoto Silicone Induction Hose (MMHOSE-CIV-06SIIHBK) is a direct replacement for the factory accordion-style airbox hose on the Honda Civic Si, built from a 5-layer silicone construction with heat-resistant embedded fibers and molded steel rings so the hose keeps its shape instead of collapsing when VTEC kicks in. This black version bolts up to the stock airbox and is engineered to work alongside your factory air intake system rather than requiring a full aftermarket intake swap.
By smoothing out the internal dimensions of the factory boot, this induction hose helps maximize airflow to the throttle body, giving your Civic Si’s air intake system a genuine efficiency upgrade without sacrificing the stock airbox setup. It’s a practical middle ground between leaving the factory rubber hose in place and going all-in on a full cold air intake system
a performing, durable silicone hose that improves on the OEM piece while keeping stock components intact. Owners can expect an increase in engine tone and throttle response, along with a hose that’s far more resistant to cracking and heat fatigue than the original accordion-style tubing.
