Product details
NGK spark plug 3978 uses the PFR7H-10 design and serves selected Saab 9-3 and 9-5 applications. The supplied fitment includes the 9-3 from 2000–2002, the 2003 9-3 SE, the 1999 9-3 Viggen, and the 9-5 from 1999–2009. In each cylinder, the plug fires a spark across its electrode gap to ignite the air and fuel charge. Worn or fouled plugs can contribute to poor starting, hesitation, and misfires, so the correct replacement reference matters during ignition service. The supplier notes that this part will be replaced by 32-045-044. Keep that replacement note in mind when matching an existing order or checking current availability.
Warranty: 24 Months / 24,000 Miles.
