Description
The Mishimoto MMAI-CIV-17SIBL is a direct-fit performance air intake engineered specifically for the turbocharged 2017-2020 Honda Civic Si, pairing a CNC-machined aluminum MAF housing with a steel wire reinforced blue silicone hose for a setup that looks as purposeful as it sounds. Unlike a simple drop-in filter swap, this complete air intake system replaces the factory intake tract from the airbox forward, delivering a noticeably deeper, more aggressive tone under acceleration and boost. Designed in Delaware, USA, this cold air intake is a bolt-on upgrade built to function with the stock ECU tune.
This air intake system is engineered to reduce restriction and improve airflow over the factory setup, and Mishimoto’s dyno testing backs it up: dyno-proven gains of up to 4 whp and 4 ft-lbs of torque on the stock tune, thanks to a smooth-flowing design that is 37-percent less restrictive than the stock intake. At the heart of the kit is the Mishimoto High-Flow Oiled Air Filter, a red multi-layered cotton air intake filter that draws cooler air from the front of the vehicle while the black powder-coated steel airbox shields the filter from underhood heat. That airbox placement, tucked closer to the hood and built around the factory air diverter, is also what helps eliminate the possibility of hydrolock, giving this cold air intake filter setup a job to do: feed the engine cooler air more efficiently than the restrictive factory box while keeping heat away from the intake filter.
Vehicle Applications
This intake is a direct fit for the 2017-2020 Honda Civic Si, covering chassis codes FC4 and FC5 equipped with the L15B7 engine. No other Civic trims or model years are covered by this specific kit.
