*** IN STOCK SHIPS TODAY *** RBS is always trying to bring new ideas to the table and here is one that you will certainly like. It is a billet alum. fuel injection port nozzle body that has a very short extension from the end of the threads allowing the end of the nozzle body not to protrude into the airflow in the intake manifold.
Also the end of the body has been radiused to help improve airflow as well. Can be used with alch. or nitro engines.
From the ball nozzle end to first thread is .500" and from first thread to end of nozzle is 1.900". Overall length is 2.40".
