Mishimoto 2017+ Honda Civic SI Performance Air Intake Kit - Blue

Our performance air intake for the 2017-2020 Honda Civic Si is finally here! This intake was engineered specifically for the new turbocharged Civic and is a direct-fit modification that will provide enhanced engine performance and improved throttle response - plus it will add a little flair under the hood! This intake has a unique and aggressive tone under acceleration and boost that will be very noticeable. The steel wire reinforced silicone intake arm improves airflow and keeps intake air temperatures under control as opposed to an aluminum design. The black-powdercoated steel airbox covers and protects the Mishimoto high performance air filter from engine bay heat and eliminates the possibility of hydrolock with the placement being closer to the hood. The box makes use of the stock air diverter found right underneath the hood that directed airflow into the stock airbox. The MAF housing has a venturi-style inlet, bringing in much smoother airflow compared to the conventional MAF housing design. This intake makes consistent dyno-proven gains of about 4hp and 4ft-lbs of torque and was designed in the USA at our Delaware headquarters. This unit is a complete bolt-on part that functions perfectly with the stock tune and includes the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship.

Product Overview

Add horsepower and sound to your ride with the new Mishimoto Performance Air Intake. This kit is engineered specifically for your car and includes everything needed to replace the restrictive stock airbox. Installation is quick and simple, perfect for some extra punch on the street or autocross course.

The Mishimoto Air Intake includes everything needed for installation, installs in under one hour, and works perfectly with the stock tune. The mandrel-bent aluminum intake pipe is available with a polished or powder-coated finish. This pipe utilizes a CNC-machined mass airflow sensor (MAF) housing to provide accurate and consistent MAF readings, which translates into a smooth power band. To reduce air intake temperatures, a powder-coated heat shield is placed between the air filter and hot exhaust manifold, significantly reducing heat-soak. The Mishimoto free-flowing air filter provides an 85% greater surface area, optimal airflow, and proper filtration of dirt and debris. The included Mishimoto oiled air filter is completely serviceable, allowing for a lifetime of reliable use. Additionally this intake kit includes a silicone coupler, clamps, and all other hardware necessary to complete a quick installation for easy bolt-on power. Along with an upgrade in power, this intake also provides an aggressive and rich intake tone that is a huge improvement over the stock intake. The Mishimoto Performance Air Intake is designed in Delaware, USA and includes the Mishimoto Lifetime Warranty.

• 37-percent less restrictive than stock intake system
• Dyno-proven maximum gains of up to 4 whp and 4 wtq on the stock tune
