Description
The Mishimoto MMAI-CIV-17SIBK is a performance air intake engineered specifically for the turbocharged 2017-2020 Honda Civic Si, a direct-fit bolt-on system built around a steel wire reinforced silicone intake arm, a black powder-coated steel airbox, and a venturi-style MAF housing. This is not a generic universal intake filter — it was designed from the ground up around the Civic Si’s engine bay to deliver a smoother, less restrictive path from the factory air diverter to the throttle body.
As a complete air intake system, this cold air intake filter setup replaces the restrictive factory intake with a design that is 37-percent less restrictive than the stock intake system, translating to dyno-proven gains of up to 4 whp and 4 wtq while running on the stock tune. The steel wire reinforced silicone intake arm improves airflow and helps keep intake air temperatures under control compared to a typical aluminum-only design, while the black-powdercoated steel airbox shields the Mishimoto high-flow oiled air filter from engine bay heat. Because the airbox is positioned closer to the hood and makes use of the stock air diverter that channels air into the factory box, this cool air intake arrangement also eliminates the possibility of hydrolock. Drivers will also notice a highly aggressive intake tone under acceleration and boost that sets this cold air intake apart from a quiet factory setup.
Vehicle Applications

Frequently Asked Questions
What vehicles does this Mishimoto cold air intake fit?
This air intake system is a direct fit for the 2017-2020 Honda Civic Si, covering chassis codes FC4 and FC5 with the L15B7 engine.
How much performance gain does this intake add?
Mishimoto reports dyno-proven maximum gains of up to 4 whp and 4 wtq on the stock tune, with the intake being 37-percent less restrictive than the stock intake system.
Does this intake work with the stock ECU tune?
Yes, this is a complete bolt-on unit that functions perfectly with the stock tune.
How does this design help prevent hydrolock?
