Blox Racing fuel injector height adapters are CNC machined from billet aluminum, then anodized. 

Height adapters are designed to fit over 14mm bore fuel injectors and help adapt a shorter injector to your specific needs. For example, using a 1/2" adapter on a 38mm injector will turn it into, basically, a 48mm injector.
