This is a replacement piston designed for use within an internal combustion engine, forming the core reciprocating component that transfers combustion energy to the crankshaft via the connecting rod. The piston must maintain correct bore clearance to ensure efficient compression, oil control, and thermal transfer to the cylinder walls. Using an incorrectly sized or worn piston results in reduced compression, increased oil consumption, and potential engine damage. Key Features Manufactured to OEM dimensional specifications for correct bore fit and ring groove geometry Supplied as a single piston unit - confirm quantity required before ordering for a full engine rebuild Sourced under the Britpart parts programme, intended as a direct replacement component When replacing pistons, also inspect piston rings, gudgeon pins, and cylinder bores for wear or scoring Vehicle Fitment Please refer to the part title and your vehicle's engine specification to confirm fitment compatibility before ordering, as no additional fitment data is provided for this SKU.
