The Nitrous Express billet fuel rail adapter is a must when installing a nitrous system on a late model electronic fuel injection Ford. This high flow adaptor makes the chore of tapping factory fuel systems safe and easy. No cutting or drilling just a quick, easy install that takes only minutes and each high flow adaptor has dual outlets for multiple uses. Can be used for 2005 to present 4.6 and 5.4 liter 3V Ford engines.
