Product Description

The Mishimoto MMAI-CIV-17SIBK Black Cold Air Intake is a direct-fit performance upgrade developed specifically for2017-2021 Honda Civic Si models equipped with the 1.5 L turbocharged I4 engine. This intake system replaces therestrictive factory intake plumbing and airbox with a precision-engineered setup designed to improve airflow,throttle response, and turbo efficiency without requiring an ECU tune on stock vehicles.

Featuring a wrinkle black finish on the intake pipe and heat shield, a CNC-machined MAF flange for accurate airflowmeasurement, and a wire-reinforced silicone elbow for enhanced durability under boost, the MMAI-CIV-17SIBK balancesperformance with long-term reliability. The included high-flow oiled performance air filter increases surface areafor improved airflow and filtration, while the integrated heat shield helps reduce intake air temperatures byisolating the filter from hot under-hood air.
