Product Details

NGK 3735 is part of the V-Power Spark Plug family, a product line focused on OE-style fitment and consistent ignition service. The plug uses a non-removable nut terminal, 5/8 hex size, and a manufacturer heat range of 6. For vehicles such as Saab 900, Saab 9000, Saab 9-3, Saab 9-5, Toyota Supra, and Aston Martin Virage, the listed fitment notes call for specific gap settings, so final gap verification is important during service.

This part cross-references Bosch 7407 and Champion Spark Plug 7408 for the same application.

What It Helps Address

• Hard starting caused by worn spark plugs
• Rough idle from inconsistent spark output
• Misfire conditions related to plug wear or incorrect gap
• Reduced throttle response from degraded ignition performance
• Maintenance intervals on older Saab and Toyota ignition systems

Installation Notes and Tips

• Confirm the vehicle-specific gap listed for your application before installation; fitment notes vary by model and year.
• Check thread diameter, reach, and seat type against the original plug specification.
• Use proper spark plug socket tools to avoid damaging the hex or insulator.
• Inspect ignition wires or coils during service to help maintain consistent performance.
• For Saab 900, Saab 9000, Saab 9-3, Saab 9-5, Toyota Supra, and Aston Martin Virage applications, follow the exact gap note shown in the fitment data.
