Product Details

NGK’s COP ignition coil line is developed for late-model domestic and import vehicles and tested in an ISO 17025 accredited lab under demanding conditions. This coil is intended for Audi A4, Audi A4 Quattro, Audi TT, Audi TT Quattro, Audi Allroad Quattro, Audi A6 Quattro, Volkswagen Golf, Volkswagen Beetle, Volkswagen Jetta, and Volkswagen Passat applications listed in the fitment data. If you are replacing a failing ignition coil on a 2001-2006 Audi A4 or a 2001-2005 Volkswagen Jetta, this NGK 48843 coil provides an OE-style replacement path with the correct COP configuration.

This part cross-references Standard Ignition UF-411 and DENSO Auto Parts 673-9300 for the same application.

Common Issues This Coil Can Address

• Engine misfire under load or at idle
• Hard starting caused by weak spark output
• Rough running or intermittent hesitation
• Check engine light related to ignition coil faults
• Loss of power from inconsistent coil performance

Installation Notes and Tips

Verify connector style, terminal layout, and engine application before installation. This coil uses a female connector and male blade terminals, with no mounting bracket included. For best results, inspect spark plugs, wiring, and related ignition components at the same time, especially on Audi TT, Audi A4 Quattro, and Volkswagen Passat models where coil-related drivability concerns often appear together.
