Volkswagen/Audi Spark Plug 04E905612D Y5KPP332S 905612

When your vehicle shows idle jitter, sluggish acceleration, noticeably higher fuel consumption, or cold start difficulty, it usually means the spark plug electrode gap is too wide or carbon buildup is severe, reducing ignition performance. This spark plug normally generates an electric spark in the cylinder to precisely ignite the air-fuel mixture, ensuring smooth engine operation, power delivery, and fuel efficiency. Compatible with multiple VW/ Audi models after 2000. OEM numbers 04E905612D / Y5KPP332S / 905612. When installing, be sure to tighten with a torque wrench to the standard torque to avoid thread damage from over-tightening or leaks from under-tightening.
