If your vehicle experiences idle vibration, sluggish acceleration, increased fuel consumption, or check engine light, it usually indicates aging or internal insulation breakdown of the original ignition coil, resulting in insufficient ignition energy or misfire. This ignition coil (OEM number 0221503035) converts low voltage to high voltage to accurately ignite the air-fuel mixture in the cylinders, ensuring smooth engine operation and power delivery. Fits multiple 4-cylinder models, including but not limited to VW Sag, Magotan, Passat, Audi A3, A4L, and Skoda Rapid EA111/EA211 series engines. Installation must be performed with the engine cold; ensure coil and spark plug contact surfaces are clean and oil-free, plug connections secure, and check that the sealing O-ring is in place to prevent water ingress and secondary failures.
