The 26mm Injector Seats for Top Feed Conversion are available for those who need to properly seal the top feed injectors in the Subaru WRX/STI. 

RallySport Direct carries highly engineered products designed to improve the performance and longevity of your vehicle brought to you by Radium Engineering. 

 

These are the Radium Engineering 26mm Machined Aluminum Injector Seats that are used in Radium's fuel rails. These are required when converting the OEM fuel injector to aftermarket fuel injectors. They simply press-fit into the intake manifold / TGV injector ports with no modifications required. Using the included FKM O-ring, they seal into the machined injector counterbore preventing vacuum or boost leaks. The injector seat bores are designed to be used with a common 14mm lower injector O-ring.
