Improved Racing Aluminium Double O-Ring LS Oil Galley Plug

• Improved Racing billet aluminum rear galley plug (“barbell”) designed for Gen III and IV GM LS-series engines
• Enhances oil flow and eliminates the possibility of unfiltered oil bypassing the filter
• Recommended upgrade to replace the factory plastic OEM plug in any engine build
• Features a secondary O-ring to fully separate dirty and clean oil, ensuring 100% filtration
• Smooth radiused fillets eliminate sharp edges, improving overall oil flow efficiency
• Bullnose tip design promotes smoother oil delivery to the filter
• Reduced shaft diameter minimizes flow restriction compared to the OEM component
• Integrated threaded M4 x 0.7 hole allows for easy removal using a standard screw

Suitable for:

• Gen III GM LS series engines
• Gen IV GM LS engines

*Do not use with the LSX engine block. These engine blocks have a slightly different oil passage and use a rear cover design that will result in interference with the oil passage plug, resulting in leaks.
