Mishimoto Performance Air Intake w/ Heat Shield for 2006-2011 Honda Civic Si - Wrinkle Black (MMAI-CIV-06SIHWBK)

Fits 2006-2011 Honda Civic Si and 2008 MUGEN Si.

Unlock the performance potential of your high-revving K-series engine with the Mishimoto Performance Air Intake. This kit is a direct bolt-on replacement for the restrictive factory airbox, engineered to improve airflow while maintaining safe air/fuel ratios on the stock tune. Dyno-testing shows maximum gains of up to 8 whp and 6 wtq, along with a significantly more aggressive intake note, particularly during VTEC engagement.

The kit features a mandrel-bent aluminum intake pipe finished in a durable wrinkle black powder coat. To ensure consistent performance and smooth power delivery, the pipe includes a precision CNC-machined mass airflow (MAF) sensor housing to provide accurate data to the ECU. An included powder-coated heat shield isolates the filter from engine bay heat to mitigate heat soak. The high-flow oiled filter provides 85% more surface area than the stock unit and is fully washable for a lifetime of reliable service.
