What is the benefit of a dry air filter?

A dry air filter, like the Injen SuperNano-Web used here, doesn't require oiling. This makes it easier to service and maintain, while still providing excellent filtration and allowing for increased airflow.

Do I need to tune my car after installing this intake?

This Injen cold air intake is designed to maintain safe air-fuel ratios on its own. For most applications, no additional tuning is required to gain the intended horsepower and sound improvements.

What does CARB EO certified mean?

CARB EO certified means the intake has been tested and approved by the California Air Resources Board. This ensures it meets emissions standards and is legal for sale and installation in California, and often in other states that follow California's emissions regulations.

Product Details

This Injen RD Series cold air intake is built with a smooth, mandrel-bent 6061-T6 aluminum tube. This design creates an uninterrupted path for air, helping to pull the coolest, densest air from behind the front bumper into your 1988-1991 Honda Civic or CRX Si's engine. It's designed to give you a noticeable boost in mid-range power and an aggressive, throaty engine sound when you step on the gas.

The intake includes a fully serviceable Injen SuperNano-Web dry air filter. This filter offers increased surface area for better airflow and filtration without needing oil. Injen has also made sure that this system helps maintain safe air-fuel ratios, so you don't need to worry about additional tuning for basic bolt-on power gains. This intake is CARB EO certified, meaning it's legal for sale in California and meets emissions standards.

This kit comes in a durable black powder-coated finish for a clean look in the engine bay. Injen backs this intake with a limited lifetime warranty, reflecting their confidence in its build quality and performance.
