300 Degree NPT Head Plugs allow access to fluids inside Nissan heads IE VG30DE(TT). For the Z32 during the '90s, race teams used scavenge pumps to drain accumulated oil from inside the heads back to the oil pan. These threaded plugs make this simple. 1/2 NPT theaded fittings may be used to connect barbed 5/8 hose or AN-10 fittings to the heads.
