The Injen IS1560P is a polished short ram cold air intake built for the 1999-2000 Honda Civic Si with its 1.6L L4 engine. The manufacturer describes a mandrel-bent T6-6061 aluminum tube that keeps airflow smooth, paired with a SuperNano-Web dry filter that can be serviced and reused. Its short ram layout is designed to fit tight engine bays while still improving how the engine breathes.
Injen says the kit adds power while keeping air-fuel ratios safe through the rev range, and it is sold as a no-tune bolt-on, so there is no calibration expense on top of the part price. The manufacturer does not publish a horsepower figure we could confirm, so expect qualitative gains rather than a dyno number. Injen also emphasizes the intake sound, promising audible character that a stock airbox cannot provide. If you are searching for a 99-00 Civic Si polished short ram, no-tune cold air intake, or a 1.6L B-series intake upgrade, this is the Injen option built to that application.
The manufacturer states this intake is built to fit the 1999-2000 Civic Si with no tune required.
The manufacturer describes the included SuperNano-Web dry filter as fully serviceable. Confirm the recommended cleaning and service steps with the manufacturer before maintaining it.
