It's a replacement plug adapter with an 8-1/2" reach to work around manifolds, baffiling, harnesses, support structures, and anything else that gets in your way. The T-handle lets you to screw and unscrew the extender into the port without a wrench. And finally, the quick connect coupler makes it a snap to hookup and disconnect your tester.
