Honda H22 DOHC VTEC cylinder head oil drain plugs for F22 and F23 block hybrids

Quantity: Two (2) Type: Billet Aluminum Plug Warranty: 1 year replacement (excluding o-rings). One single replacement of o-ring set within the first year.   These billet plugs reduce the work required to put H22, F20B, and H23A (VTEC) cylinder heads on SOHC F22A, F22B, and F23A cylinder blocks. This engine combination is sometimes called a G22 or G23, also refereed to as a H22/F22 or H22/F23 hybrid. The trick is the how they use dual Buna-N o-rings to seal the holes, very similar to billet Honda B-series cam caps. These plugs will make building this engine combination much easier than before. Your typical options are to weld the holes up solid, drill & tap for threaded plugs, or install freeze plugs. Welding the head requires a professional and milling the head afterwards. Threading the holes for plugs also requires a pro since they are such large plugs. Freeze plugs can end up leaking with the constant heat cycles. These plugs can be installed in seconds and removed just as fast.
