2002 Audi S4 Ignition Coils

Carquest Premium ignition coils meet or exceed original equipment (OE) specifications and are developed by top OE/OES manufacturers to ensure superior performance. All of our Carquest Premium ignition coils are developed by IATF 16949 certified manufacturers for consistent durability and long-lasting performance. These ignition coils use high-quality components and will utilize optimized designs on applications where the OE ignition coil had frequent failures. We require stringent testing standards to ensure proper fit and performance for each application and stand behind our Carquest Premium ignition coils with an industry-leading warranty. Carquest Premium ignition coils are part of our Carquest Vehicle Solutions, which is a full line of engine management and electronics products that help control ignition, fuel delivery and emission systems. Carquest Vehicle Solutions are OE-quality parts designed, engineered and tested by world-class manufacturers to ensure a reliable and long-lasting repair.

Product Features:

• Coil drivers match OE for current limit, electrostatic discharge (ESD) protection and multi-spark
• Segmented secondary bobbins to distribute high voltage and prevent shorting
• Extensive design validation testing to ensure long-lasting reliability
• 100% end-of-line tested to ensure proper performance
• Carquest Vehicle Solutions Technical Support available from ASE certified technicians: 1-866-687-5413

Delphi OE technology ignition products are validated to match the vehicles system; OE quality replacement parts for the right fit , form and function; Delphi coils provide OE performance, durability and electromagnetic capacity level requirements.

Product Features:

• Delphi coils provide OE performance, durability and electromagnetic capacity level requirements
• Delphi ignition coils are designed to operate as part of an integral engine management system to insert power into spark plugs and ensure fast starts; consistent engine performance and optimized fuel efficiency
• Delphi uses winding process techniques to control the length of wire between adjacent windings; that’s important since more length means greater voltage differences and can create more pressure that could break down the insulation and wire coating
• We back our ignition coil design with proven materials, such as high quality wires and wire coating that resists the cracks, pin holes and imperfections that most often lead to failure issues

Every WSO ignition coil is developed and designed for its specific application, and engineered for maximum performance. WORLD SOURCEONE ignition coils are designed to operate reliably and dependably under all operating conditions and engine rpm ranges, providing the highest engine performance, low exhaust emissions, and fuel economy objectives. WSO Direct Ignition Coils are designed to adapt the required energy output to match engine-operating conditions and deliver the optimum energy level needed to ignite a diluted stratified charge.
