Head gasket set for OS SPEED 12TZ SP2

This is an RC-scale head gasket set intended for the OS SPEED 12TZ SP2 engine model, supplied by O.S. Engine and identified as OS21531410. The set is designed to restore or replace the sealing surfaces between the cylinder head and crankcase during routine maintenance or rebuilds.

Use this gasket set when disassembling the cylinder head for inspection, replacing worn gaskets, or performing tuning procedures that require the head to be removed. Proper gasket condition helps maintain compression and consistent combustion behavior in nitro RC engines.

If you are unsure about fitment, verify the seller listing or consult technical documents for OS SPEED 12TZ SP2 compatibility.
