Product Description

The Mishimoto MMAI-CIV-06SIWBK Wrinkle Black Performance Air Intake with Heat Shield is a direct-fitupgrade engineered specifically for the 2006-2011 Honda Civic Si equipped with the 2.0 L K20Z3 naturally aspirated I4 engine. This cold air intake replaces the restrictive factory airbox and factory tubing with a mandrel-bent aluminum pipe and an oiled high-flow performance filter to improve airflow, throttle response, and overall engine breathing while maintaining safe air/fuel ratios on the stock ECU tune. Dyno-proven gains of up to +8 hp and +6 ft-lbs of torque highlight measurable performance improvements without sacrificing reliability.

A wrinkle black powder-coated heat shield helps reduce intake air temperatures by shielding the filter from hot engine bay air, minimizing heat soak and improving consistency in power delivery. The CNC-machined mass airflow (MAF) flange ensures accurate airflow measurement for smooth throttle response across the powerband. Installation is straightforward and can be completed in under one hour using the included silicone coupler, clamps, and mounting hardware - no front bumper or splash shield removal is required.

This intake system is CARB legal under Executive Order D-759-1, making it compliant for use in all 50 U.S. states when installed according to manufacturer instructions. The Mishimoto Lifetime Warranty backs the product's build quality and material integrity. Coverage is confirmed for 2006 through 2011 Honda Civic Si models; 2012 and later models are not supported.
