Product Description

The Mishimoto MMAI‑CIV‑06SIHWBK Black Cold Air Intake with Heat Shield is a direct‑fit performance upgrade designed specifically for the 2006–2011 Honda Civic Si equipped with the 2.0 L K20Z3 engine. This intake system replaces the restrictive factory airbox with a mandrel‑bent aluminum intake pipe and high‑flow oiled filter to improve airflow, throttle response, and induction sound without sacrificing drivability.

The included wrinkle black heat shield helps reduce intake air temperatures by shielding the filter from hot engine bay air, while the CNC‑machined MAF flange ensures accurate airflow measurement for smooth power delivery. Installation is quick and straightforward, taking less than an hour and requiring no front bumper or splash shield removal. Dyno‑proven gains of up to +8 hp and +6 ft‑lbs of torque can be achieved on a stock tune, with additional gains possible when paired with an ECU tune. This intake is CARB‑executive order approved (D‑759‑1), making it legal for use in all 50 states when used as directed.

Fitment is confirmed for all 2006–2011 Honda Civic Si models (FG2/FA5 chassis, FWD). The Mishimoto Lifetime Warranty covers material and workmanship for the life of the product. Follow recommended clamp torque specs during installation for optimal performance and longevity.
