DeatschWerks Ford 4.6 3-valve fuel rail fits 2005–2010 Ford Mustang GT SOHC models and the product notes explicitly state it does not fit DOHC or supercharged variants. The rail is specified to match that SOHC application and provides the correct mounting and fuel feed arrangement for the listed naturally aspirated GT engines.
