Don’t stifle your VTEC — let it breathe free with the latest in our line of Honda Civic performance parts! This Mishimoto Civic Si induction hose replaces the accordion-style stock airbox hose with a high-quality silicone unit. These 5-layer silicone hoses feature heat-resistant embedded fibers for increased pressure and heat tolerances. Molded steel rings help 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 power figures 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 Civic Si performance parts, feature the Mishimoto Lifetime Warranty.
