Audi A6 Passat Lingyu 1.8T Spark Plug 101000063AA PFR6Q High-Efficiency Ignition

Is your vehicle showing rough idle, weak acceleration, noticeable fuel consumption increase, or cold-start difficulties? This is often due to spark plug aging, wide electrode gap, or carbon buildup causing reduced ignition energy. When functioning normally, this spark plug efficiently ignites the air-fuel mixture to ensure smooth power output and stable fuel economy. OEM numbers 101000063AA / PFR6Q; fits Audi A6 (2000-2005) and Passat B5 1.8T. Installation requires torque wrench to the standard torque; avoid over-tightening or under-tightening and ensure electrode gap is 0.8 mm.
