Car Engine Parts Piston Kit with Ring OE A2640301800 A2640302100 for Mercedes-benz C257 CLS 300 M264.920 2.0L STD 0.5 83mm

Car Engine Parts Piston Kit with Ring OE A2640301800 A2640302100 for Mercedes-benz C257 CLS 300 M264.920 2.0L STD 0.5 83mm

When your Mercedes-Benz CLS (C257) 300 experiences delayed power response, abnormal oil consumption or lack of acceleration, this is most likely a clear indication of wear on the core components of the M264.920 2.0-liter turbocharged engine - the pistons and piston rings. We have specially designed the original factory standard piston kit (part number: A2640301800 / A2640302100) for this advanced engine. This kit is manufactured strictly in accordance with Mercedes-Benz engineering specifications, providing a complete solution including the piston body and a precision piston ring set. This kit is an ideal choice for restoring engine performance, controlling oil consumption and performing preventive maintenance, aiming to restore the agile throttle response and excellent fuel efficiency of your luxury vehicle.

Solving the problem of abnormal oil consumption in turbocharged engines 
Repair the power reduction and insufficient compression caused by the wear of pistons and piston rings. 
Preventive maintenance of the engine and performance restoration 
Applicable to Mercedes-Benz CLS C257 300 and related models equipped with the M264.920 2.0L turbocharged engine. 
Choosing this original factory standard piston kit is a crucial investment in the performance and long-term reliability of your Mercedes-Benz engine.

Precision original factory matching, perfect compatibility guarantee
This kit strictly follows the original factory technical standards of Mercedes-Benz. The core part numbers A2640301800 and A2640302100 ensure a 100% perfect match with the M264.920 2.0T turbocharged engine. Its standard diameter (STD) of 83mm (design) is suitable for the original engine block and also offers an option of 0.5mm repair grade, providing flexible choices for the precise repair of the cylinder wall, ensuring that the clearance between the piston and the cylinder block is restored to the optimal state, guaranteeing smooth and stable power output. 
Exquisite material and craftsmanship, capable of withstanding the harsh conditions of turbocharging
The piston is cast from high-strength aluminum alloy and undergoes precise heat treatment, featuring excellent heat resistance, wear resistance, and lightweight characteristics. The piston ring assembly is made of special alloy steel and treated with advanced surface treatment technologies (such as PVD coating), which can maintain lasting elasticity and sealing force in the high-temperature and high-pressure environment caused by turbocharging, effectively controlling the entry of engine oil into the combustion chamber, and fundamentally solving the problem of abnormal oil consumption. 
Restore engine performance, optimize power output
By re-establishing precise cylinder sealing, this kit can effectively restore the engine's compression ratio and cylinder pressure, significantly enhancing the low-speed torque response and making the turbo intervention more rapid. The optimized combustion chamber seal also brings about more efficient combustion, helping to improve fuel economy and reduce emissions, allowing your CLS 300 to regain its factory performance and power level. 
Complete set solution, the preferred choice for professional maintenance
What we offer is a complete set including all necessary components such as pistons, oil rings, gas rings and retaining pins. Professional maintenance workshops can obtain all core components at once, avoiding specification differences or quality variations caused by decentralized procurement. This significantly improves the efficiency and final quality of engine major repairs, ensuring the long-term reliability of the repaired engine's performance.
