LT4 Port Injection Plates - Ultra Low

These plates allow the addition of port injection with 34mm injectors to LT4 headed engines and are intended to clear the Magnuson 2650 when using DSX valve covers (other valve covers may fit, but we cannot guarantee fitment). These measure only 16mm thick which translates to a 0.743" height increase of the supercharger. These do require the use of smaller lower injector o-rings (3mm CS x 8.5mm ID) which are available for purchase if you do not have them on your injectors already.
