Improved Racing Engine Block Oil Galley Barbell Plugs

Improved Racing's engine block oil galley barbell plugs feature a second O-ring that completely seals off the dirty oil from the clean oil, forcing 100 percent of the flow through the filter. Sharp corners were avoided and machined as smooth fillets to improve oil flow, while the bull nose tip helps smooth oil flow to the oil filter. The shaft diameter is smaller than the OEM plastic barbell to minimize flow restriction, and the threaded hole allows for easy removal with any 4mm x 0.7 threaded screw. Please refer to the Applications tab when ordering to confirm the fitment.

Features of Improved Racing's barbell plugs include:

* Direct replacement for plastic OEM barbell plug
* Precision CNC-machined from billet 6061-T6 aluminum
* Viton® rubber O-rings offer high-temperature resistance and excellent chemical compatibility with engine oils Show Less
