大众速腾/朗逸/宝来/甲壳虫/途观 火花塞 101905620 PZFR5N-11T 精准点火

For post-2000 VW Jetta/Passat/Classe/A Beetle and Tiguan 1.4T/1.6L/2.0L models, you can choose ZF-brand OEM number 101905620/PZFR5N-11T spark plug. This component is installed in the cylinder head threaded hole, generating a spark at the end of the compression stroke to ignite the air–fuel mixture, the core for precise ignition. Replacement difficulty is moderate; labor time about 0.5–1 hour, tighten with a dedicated torque wrench to standard torque. If idle jitter, weak acceleration, or noticeably increased fuel consumption occur, electrode wear is usually the cause.
