KATANA Injector Extensions

The THP KATANA Injector Extensions allow the use of 'short' LS3 style injectors with a 34mm O-ring spacing on KATANA Port Plates.  They can be used as a top or bottom extension to convert an LS3 length injector into an LS1 'long' injector. Note that we recommend an extended tip injector when used as a bottom extension for use with a Magnuson 2650. 

Each extension is black anodized for durability and comes complete with a Viton O-ring.
