Injen SP1578P SP Series Polished Cold Air Intake, Honda Civic Si 2.0L 2006-2011

Description

Upgrade the factory air intake on your Honda Civic Si with the Injen SP1578P SP Series cold air intake. Injen dyno testing shows gains of up to 10.7 horsepower and 11.2 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.

At the heart of every SP Series intake is Injen's tuned-intake engineering. The 6061-T6 aluminum tube used on the Honda Civic Si is designed to reduce restriction and turbulence, and Injen validates each design on the dyno so power increases arrive without compromising air/fuel ratios. This kit incorporates Injen's patented MegaRam (MR) Technology and Air Fusion to help maintain safe air/fuel ratios while maximizing gains.

Filtration is handled by Injen's SuperNano-Web dry air filter, a synthetic, fully serviceable element that captures fine particles while providing a large surface area for airflow. No oiling is required, which keeps sensors on the Honda Civic Si clean. When service is due, order Injen replacement filter part number X-1014-BB. An optional Injen Hydroshield pre-filter (1033BLK or 1033RED) is available for added protection from water and debris.

The polished aluminum finish adds a bright, show-quality look to the engine bay. Beyond the performance gains, the intake adds a satisfying induction sound and a clean under-hood appearance. Injen stands behind the quality of its parts with a Limited Lifetime Warranty for the original purchaser.

CARB Legal: This Injen intake is exempt under California Air Resources Board Executive Order D-476-8, covering 2006-2011 model years, and is legal for use on emissions-controlled vehicles in all 50 states within that coverage.
