Audi A4 Avant, A5 2002-2004, 2010-2021 CAEA CAEB CAED CDNA CDNB CDNC CESA CETA CFKA Auto Engine Parts 910703 Cylinder Head CAEA CAEB CAED for VW Audi A4 A5 A6 TT Q5 EA888 – OEM 06H103063L

Product Overview: This complete cylinder head assembly is a direct-fit replacement engineered for the CAEA CAEB CAED CDNA CDNB CDNC CESA CETA CFKA petrol engine, a powerplant widely used in Audi A4 Avant and related platforms. It is supplied fully assembled with finish-machined camshaft journals, valve seats, valve guides and combustion chambers, so a cracked, warped or valve-damaged original head can be replaced without additional machining work.

Key Features: The casting is CNC-machined to original equipment tolerances for accurate deck flatness, correct valve seat concentricity and consistent combustion chamber volume across every cylinder. Valve guides and seats are pre-installed and honed for even sealing and balanced compression, and the cast iron or aluminium construction with reinforced walls around the valve bridge and fire deck improves durability under sustained thermal and mechanical load.

Vehicle Compatibility: This assembly is compatible with Audi A4 Avant (2002-2004) and Audi A5 (2010-2021). Typical production coverage spans 2002-2004 and 2010-2021, although availability varies by market and model year.

Specifications: Engine code CAEA CAEB CAED CDNA CDNB CDNC CESA CETA CFKA; four-cylinder petrol configuration; material Cast Iron or Aluminium; STD; new condition; supplied as a complete assembly; 12 Months warranty; place of origin Zhejiang, China; intended for replacement and repair use.

OEM / Reference Numbers: 06H103063L, 06H103064L, 06H103063, 06H103064LX, 06H103064AC, 06H103264AX and 910703. These references cover several production revisions of the same basic casting, so cross-reference them with the casting marks and part label on the original component to confirm the correct variant.

Applications: Suitable for Audi A4 Avant and Audi A5, covering everyday repairs, engine rebuilds, workshop overhauls and fleet maintenance where a factory-specification component is required. It is well suited to family cars, hatchbacks, sedans and small SUVs used in daily driving, as well as workshop overhauls and preventive maintenance programmes.

Benefits / Replacement Information: Installing this assembly restores lost compression, corrects coolant loss and combustion leakage caused by cracking or distortion, and removes the expense of machining and rebuilding the original head. A correctly specified replacement reduces the risk of repeat failure, helps restore original fuel economy and emissions performance, and returns the engine to reliable service with a predictable service life.

Installation or Fitment Notes: Confirm the engine code CAEA CAEB CAED CDNA CDNB CDNC CESA CETA CFKA and OE number before ordering, and inspect the block deck and piston protrusion for flatness and correct height before fitting. Use new gaskets, head bolts and seals during installation, follow the manufacturer's torque sequence and tightening values, and refill with the correct grade of oil and coolant.
