Injen 22-23 Honda Civic/Civic Si 1.5L 4 Cyl. Polished Cold Air Intake - SP1586P

Brand: Injen

SKU: injSP1586P

availability: In stock

$422.60

The factory intake tract on the 2022-2024 Honda Civic and 2023-2024 Acura Integra is very restrictive from the factory and limiting power output by choking the turbo. The new Injen SP1586 cold air intake opens up that intake tract with a massive 3.00in aluminum intake tube that transitions into Injen Technology's patented step-down process called, MegaRam? Technology (or MR Technology? for short). This patented MegaRam? Technology allows the engineers at Injen to fine-tune fuel trims and maximize power output. Directly after the MR Technology? step-down, the system briefly enlarges to 2.50in before entering the factory turbo inlet. This is done to maintain airspeed for improved throttle response. The longer tube found on this cold air intake also promotes increased power across the entire RPM band and not just at the top-end like the majority of short-ram and enclosed systems. Features & Benefits Note: This product is not currently CARB exempt and is not available for purchase in California or for use on any vehicle registered with the California Department of Motor Vehicles. Manufactured from 2.50in and 3.00in Mandrel-Bent 6061-T6 aluminum intake tubing Smooth intake piping eliminates restrictions and improves airflow Fully serviceable Injen SuperNano-Web dry air filter Optional Hydroshield part...
