Does this Injen cold air intake require a tune for my 1999-2000 Honda Civic?

No, this Injen RD Series cold air intake is designed to provide a bolt-on power increase while maintaining safe air-fuel ratios. It is CARB EO certified and typically does not require an ECU reflash for proper operation.

How do I maintain the Injen SuperNano-Web air filter?

The SuperNano-Web filter is fully serviceable. You can clean it using a dedicated filter cleaning solution and re-oil it if necessary, or purchase a replacement filter (part number X-1012-BB) when it's time.

What is the benefit of a polished finish on the intake tubing?

The polished finish on the aluminum tubing provides a clean and custom look in your engine bay. It also helps to reflect heat away from the intake charge, though the primary benefit is aesthetic.

Product Details

If you're looking to get more out of your 1999-2000 Honda Civic EX, HX, or EL, this Injen RD Series polished cold air intake is a solid option. It's designed to replace your restrictive factory airbox and tubing with a smoother, more direct path for air to enter your engine. This means your engine can breathe easier, which often translates to a noticeable increase in horsepower and a more aggressive sound under acceleration.

The heart of this system is the mandrel-bent 6061-T6 aluminum tubing. Mandrel bending ensures the tube maintains a consistent diameter throughout its length, unlike crush-bent tubing which can create restrictions. This smooth path helps pull in cooler, denser air from behind the front bumper, which is key for generating power. It also includes a serviceable Injen SuperNano-Web dry air filter, which offers good airflow and filtration without needing oil. The polished finish on the tubing gives your engine bay a clean, custom look.

This intake is CARB EO certified, meaning it's legal for sale in California and other states that follow its emissions standards. It's designed to provide a bolt-on power increase while maintaining safe air-fuel ratios, so you typically won't need to retune your ECU. You'll also notice a more throaty exhaust note when you step on the gas.
