Specifications
Part Details:
This Injector Dynamics bottom adapter converts any 14mm ID injector to a 16mm bottom fitment, replacing the factory Denso-style cushion on the 2008 to 2021 Subaru STI, 2008 to 2014 Subaru WRX, and 2005 to 2009 Subaru Legacy GT. It adds 3.5mm of installed height to properly seat the injector in the intake manifold, using a 14x1mm bottom O-ring with a 16mm outer diameter for a correct, leak-free seal.
Anodized grey for durability. Sold individually, order the quantity needed to match the injector set being installed.
