Original Quality Piston Assembly 06L107065BD +0.5 for Audi B9

Oversize piston assembly with +0.5mm dimension engineered for engine rebuilding on Audi B9 models. Premium aluminum alloy material forms the piston body, featuring excellent thermal conductivity and low thermal expansion characteristics to maintain stable clearance inside the cylinder bore under high combustion temperature. Optimized skirt profile reduces friction loss between piston and cylinder wall, cutting down oil consumption and improving engine response during acceleration. Matching piston rings and wrist pin are included as a complete set to simplify assembly work for engine overhaul.

Carefully controlled machining tolerance guarantees perfect fitment after cylinder boring. Every piston undergoes strict weight sorting to keep balanced mass across all cylinders, preventing abnormal vibration and power drop after installation. Advanced anti-scuff coating on the piston skirt provides extra protection against metal contact during cold start and heavy load operation. Worn standard size pistons will cause excessive blow-by, burning oil and decreased compression. Choosing this +0.5mm oversize piston assembly matches the reamed cylinder, restores original compression ratio, recovers engine power output and reduces oil burn issues. It serves as a reliable aftermarket solution for engine repair and rebuilding projects.
