Injen Black Cold Air Intake Honda Civic SI 2017-2020 Injen

Part #: SP1581BLK

Got a new Si? Give it the airflow it deserves. Injen’s new cold air intake (CAI) SP1581 adds power gains of up to 21 hp and 19 ft. lbs. of Torque. This Civic Si intake uses a mandrel-bent aluminum tube, allowing for smoother, uninterrupted airflow straight into the turbo. The SP1581 utilizes our patented MR Technology and Air Fusion. To pull the coolest densest air possible the SP1581 reaches into the lowest depths of the engine bay to keep the air filter isolated from unwanted engine bay heat. Helping keep your air charge nice and cool. The piping for the SP1581 is available with either a polished, wrinkle red or laser black finish to maximize your engine bay aesthetics the way you want.

Handling the filtration duties on this cold air intake is the Injen SuperNano-Web Dry air filter. Which provides some of the greatest flow and unbeatable filtration available. The Injen SuperNano-Web Dry air filter does not require any oil which makes it easy to clean and care for. The Injen SP1581 CAI system comes complete with all the required hardware to allow for a hassle-free and easy installation. On top of all that, this kit can also convert to a short ram intake which can help you out during the rainy seasons and, like all Injen parts, this intake is backed by our unbeatable Limited Lifetime Warranty!
