Upgrade the intake system in your Honda Civic Si with the Mishimoto MMHOSE-CIV-06SIIHBK Black Silicone Induction Hose. Designed as a direct replacement for the factory accordion-style airbox hose, this performance-focused component helps deliver smoother, more consistent airflow to the throttle body. Its streamlined internal surface reduces turbulence while maintaining compatibility with the stock airbox, making it an effective upgrade without requiring a complete aftermarket intake system.
Constructed from five layers of durable silicone reinforced with heat-resistant embedded fibers, this Civic Si induction hose is engineered to withstand elevated underhood temperatures and increased pressure. Molded steel support rings help maintain the hose shape during demanding driving conditions, reducing the risk of collapse when engine airflow increases under VTEC operation. The result is improved throttle response, enhanced engine sound, and dependable airflow throughout the rev range.
The Mishimoto MMHOSE-CIV-06SIIHBK installs in under 30 minutes using standard tools and is designed for a secure fit on compatible factory components. It fits 2006 Honda Civic Si models with the 2.0-liter PNN4 engine, 2007-2010 Honda Civic Si models with the 2.0-liter PNN3 engine, and 2011 Honda Civic Si models with the 2.0-liter SPNM engine. Backed by the Mishimoto Lifetime Warranty, this black silicone induction hose provides a practical balance of performance, durability, and stock-style installation. This product is not CARB approved and may require acknowledgment of emissions-related restrictions.
