{"product_id":"piston-assy-4-6hc","title":"Piston Assy 4.6Hc for Discovery 2 (1998 – 2004) 4.6L V8 Petrol - Standard - High Compression – ERR5554G","description":"\u003cp\u003eThis is a standard-bore, high-compression piston assembly for the Land Rover 4.6L V8 (Rover V8) engine, designed as a direct replacement for the original piston used in Discovery 2 and Range Rover P38 applications. The high-compression designation indicates an elevated compression ratio compared to standard-output variants, making correct part selection critical - fitting a mismatched piston will result in incorrect compression, poor combustion efficiency, and potential engine damage. SKU ERR5554G corresponds to the OEM Land Rover part reference for this specification.\u003c\/p\u003e\n\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eStandard bore diameter - suitable for unworn or freshly honed bores at original factory dimensions\u003c\/li\u003e\n\u003cli\u003eHigh-compression piston crown profile specific to 4.6L V8 high-compression engine variants\u003c\/li\u003e\n\u003cli\u003eSupplied as a complete piston assembly including rings and gudgeon pin where applicable\u003c\/li\u003e\n\u003cli\u003eEight pistons are required for a full engine rebuild - confirm engine compression specification before ordering\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eVehicle Fitment\u003c\/h4\u003e\n\u003cp\u003eFits Discovery 2 (1998–2004), Range Rover P38 (1995–2002), and Defender (1986–2006), all with the 4.6L V8 petrol engine; high-compression specification applies specifically to Discovery 2 and certain Range Rover variants.\u003c\/p\u003e\n\u003cp\u003eNot sure about fitment?
