Sharp corners were avoided and machined as smooth fillets to improve oil flow, while the bullnose tip helps smooth oil flow to the oil filter. The shaft diameter is smaller than the OEM plastic barbell to minimize flow restriction. A threaded hole was added so that the barbell can be easily removed with any M4x0.7 screw.\u003c\/p\u003e\n\u003ch2\u003eHow Does it Work?\u003c\/h2\u003e\n\u003cp\u003e\u003ciframe src=\"https:\/\/www.youtube.com\/embed\/RagunXgBJu8\" width=\"315\" height=\"560\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003ch2\u003eFeatures and Benefits\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDirect replacement for plastic OEM barbell plug.\u003c\/li\u003e\n\u003cli\u003ePrecision Swiss CNC-machined from billet 6061-T6 aluminum.\u003c\/li\u003e\n\u003cli\u003eDesigned to reduce fluid restriction and maximize oil flow.\u003c\/li\u003e\n\u003cli\u003eSecond O-ring completely seals the dirty side of the rear oil passage from the clean side, preventing dirty oil from flowing to the engine bearings.\u003c\/li\u003e\n\u003cli\u003eFKM (Viton®) rubber O-rings are used for its ideal compression set (for a long-lasting seal), high temperature resistance, and excellent chemical compatibility with engine oils.\u003c\/li\u003e\n\u003cli\u003eThreaded M4x0.7 hole allows for easy removal from engine block.\u003c\/li\u003e\n\u003cli\u003eMade in the USA.\u003c\/li\u003e\n\u003cli\u003eLifetime Warranty.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eIncludes\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1 x Swiss CNC-machined billet aluminum rear oil gallery plug \"barbell.\"\u003c\/li\u003e\n\u003cli\u003e2 x AS568 Dash Number 111 Size FKM (Viton) O-rings.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eApplications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cem\u003e\u003cstrong\u003eDo not use with the LSX engine block\u003c\/strong\u003e\u003c\/em\u003e.
