T-series MG engines use cupped core plugs to seal the engine's water passages, and currently-available core plugs are supplied in steel. These steel core plugs will rust and leak, often in less than a year. For this reason I have had a run of brass core plugs made, and have already sold more than a thousand sets of plugs to fit the XPAG/XPEG engines. These high-quality core plugs are guaranteed not to rust, and will literally last as long as your engine rebuild. Prices are $28 (including US Priority postage) for a complete set of nine core plugs (including the cam end plug).

NOTE: My set of core plugs includes 9 plugs including the cam plug; other sets do not include that brass core plug. Also, these core plugs are proudly Made in the USA, and not overseas.
