The CJM Industries ram-air duct is designed to fit driver side Honda Civic's. It replaces the factory radar cover with a duct opening. This is for the duct file only, no other pieces are included. You will have to piece together a system that works for your car depending on your needs.
This duct works with bumper trim OEM part #XXXXX (Embossed on backside of the bumper cover).
- If your vehicles has factory lane and/or proximity radar it will need to be removed or relocated. Brackets and wiring to move the radar sensors are not included.
- If your car does NOT have the OEM radar cover - we also sell the driver side OEM grill with the proximity radar opening that can be installed on a non-radar optioned Civic. When both parts are purchased together we will install the duct into the grill cover for you before shipping.
The below items are not included. These are some options that may, or may not work for your install depending on your intake, and factory options. We cannot provide support on this assembly because it will vary depending on the other parts you have installed.
