Champion Iridium Spark Plug 9702 Overview
Champion Iridium 9702 is a secondary ignition spark plug built with a fine-wire iridium center electrode and a platinum ground electrode for a focused spark event. It is a direct-fit option for select Audi, Volkswagen, and Porsche applications that call for the KA7ZWYPB4 plug type.
Key Features
- Fine-wire iridium center electrode for sharp spark focus
- Platinum ground electrode core for durable ignition performance
- Pre-gapped to 0.040 in. / 1.02 mm
- J-gap ground electrode tip design
- Resistor type spark plug
- Flat seat design with 0.865 in. reach
- 12 mm thread diameter and 16 mm hex size
- Champion Iridium line construction for modern ignition systems
Product Details
The Champion Iridium line is engineered around a fine-wire iridium center electrode paired with a platinum ground electrode to help deliver a concentrated spark at the plug gap. Part number 9702 uses a J-gap design, a non-removable nut terminal, and a resistor configuration, making it a practical OE-style replacement for vehicles that specify plug type KA7ZWYPB4. This spark plug is listed for 2004-2006 Porsche Cayenne, 2004-2006 Volkswagen Touareg, 2004 and 2008 Volkswagen R32, 2004-2006 and 2008-2009 Audi TT Quattro, 2006-2009 Audi A3 Quattro, and 2007-2008 Volkswagen Eos.
This part cross-references Bosch YR7LPP332W and Carlson 7563 for the same application. Champion 9702 is also referenced by OE-style numbers including 101905606A and 95517021990.
What It Helps Address
- Rough idle caused by worn spark plug electrodes
- Hard starting from weak or inconsistent spark delivery
- Misfire conditions tied to incorrect plug gap or plug wear
- Loss of throttle response from degraded secondary ignition performance
- Service replacement needs on vehicles using KA7ZWYPB4 plug type
Installation Notes
Verify the vehicle calls for plug type KA7ZWYPB4, 12 mm thread diameter, 0.865 in. reach, flat seat, and the specified gap before installation. For fitment-based searches, this plug is commonly selected for Audi A3 Quattro, Audi TT Quattro, Volkswagen Eos, Volkswagen R32, Porsche Cayenne, and Volkswagen Touareg applications. Use the manufacturer-specified torque procedure and confirm the ignition system is in good condition before final assembly.
Quality Assurance
Champion designs the Iridium line for precise spark focus and stable ignition performance in modern engines. Part number 9702 follows the listed OE-style dimensions and electrode materials for the applications shown above.
