Volkswagen Nickel Alloy Spark Plug 101905601A K7HER2 Ignition System

After 2000 models of Jetta, Santana, etc., use nickel alloy spark plugs with original factory numbers 101905601A or K7HER2 for direct replacement. These plugs reliably ignite the air-fuel mixture, ensuring normal engine operation, and addressing cold-start, acceleration lag, and rising fuel consumption. If idle shakes, acceleration is weak, or there is leakage near the ignition coil, replace promptly to restore power.
