Injen SP1581BLK SP Series Black Cold Air Intake, Honda Civic Si 1.5L Turbo 2017-2020

Description

Upgrade the factory air intake on your Honda Civic Si with the Injen SP1581BLK SP Series cold air intake. Injen dyno testing shows gains of up to 29 horsepower and 25 lb-ft of torque. This direct-fit system is engineered to improve airflow, sharpen throttle response and add an aggressive induction sound without additional tuning.

The SP Series is Injen's flagship line of tuned aluminum air intakes. Each system is built around 6061-T6 aluminum tubing sized and shaped for the Honda Civic Si, giving intake air a smooth, uninterrupted path to the throttle body while the tuned design holds a safe air/fuel ratio across the rev range. This kit incorporates Injen's patented MegaRam (MR) Technology and Air Fusion to help maintain safe air/fuel ratios while maximizing gains.

Every kit includes an Injen SuperNano-Web dry filter. The synthetic nano-fiber media traps fine dust without oil and flows a large volume of air, making it well suited to daily driving in the Honda Civic Si. When service is due, order Injen replacement filter part number X-1062-BB. An optional Injen Hydroshield pre-filter (1031BLK) is available for added protection from water and debris.

A durable black powder-coated finish gives the engine bay a clean, understated look. The system provides a deeper, more aggressive intake tone under full throttle and installs with basic hand tools. Injen designs and manufactures its intakes in Pomona, California, and backs them with a Limited Lifetime Warranty.
