[ENG-QR25-CH-001] 2001–2013 Nissan X-Trail 2.5L QR25DE Complete Cylinder Head Assembly

Premium Performance

The QR25DE complete cylinder head assembly is a direct-fit replacement unit for the 2.5L Nissan QR25DE 16-valve DOHC petrol engine. It is supplied fully assembled with camshafts, valves, valve guides and valve seats already installed, so the workshop is not paying labour for a bare casting to be built up. The casting is high-strength aluminium alloy with a CNC precision-machined deck and combustion chambers for accurate sealing and correct valvetrain geometry, making it the practical answer to a warped, cracked or overheated original head.

• Direct replacement for QR25DE 2.5L / QR20DE 2.0L Nissan petrol engines
• Integrated camshaft housing design with camshafts, valves, guides and seats pre-installed
• High-strength aluminium alloy casting, CNC precision-machined deck and combustion chambers
• Water-cooled inline 4-cylinder, DOHC 16-valve configuration
• Manufactured under ISO/TS 16949 and ISO 9001 quality systems (supplier-declared)
• E/e-mark certified (supplier-declared)

Vehicle Compatibility

The cylinder head itself is not handed, so it suits both Right-Hand Drive (New Zealand / Australia) and Left-Hand Drive vehicles. Confirm the original part number against your vehicle before ordering.

Fitment note: the QR25DE was produced in several generations with different head and gasket part numbers. This listing carries OEM cross-references 11040-MA00A, 11041-MA00A, 11040-8H301 and 11040-8H302 as published by the supplying factory. Always confirm the part number for your exact vehicle and year before ordering.

Installation Notice

Professional installation is recommended. Head bolts are torque-to-yield and must be replaced, not reused.

Verify fitment against your vehicle's VIN or original part number before ordering.
