Denso 3435 Spark Plug

Denso Iridium Long Life Spark Plug 3435

Denso 3435 is an Iridium Long Life spark plug built for OE-style ignition performance, durability, and emissions control. It uses an iridium center electrode, a platinum chip ground tip design, and a 0.8 mm pre-gap for consistent spark delivery across a wide range of import and domestic applications.

The Iridium Long Life line is designed for drivers who want stable ignition performance and extended service intervals in vehicles such as Toyota Tacoma, Toyota 4Runner, and Mazda Miata applications. This Denso spark plug is engineered to match factory-style specifications for thread size, reach, seat type, and heat range.

• Platinum chip ground electrode tip design for durability
• 5000 ohm resistance for ignition system compatibility
• 0.8 mm pre-gap for factory-style setup
• Flat seat, 14.00 mm thread diameter, and 19.00 mm reach
• Manufacturer heat range 16 for specified OE applications
• Compatible with a broad range of Toyota, Nissan, Mazda, Lexus, and Chevrolet models

Product Details

Denso 3435 is manufactured to meet strict OE performance, durability, and emissions standards. The copper core center electrode supports efficient heat transfer, while the nickel ground electrode core and standard ground configuration help maintain stable ignition characteristics. This spark plug is a direct-fit style replacement for many vehicles that call for an iridium long life plug, including 2001-2005 Toyota Echo, 1995-2000 Toyota Tacoma, and 2004-2005 Mazda Miata applications. This part cross-references DENSO Auto Parts SK16PR-F8 for the same application.

What It Helps Address

• Hard starting caused by worn or fouled spark plugs
• Rough idle and inconsistent combustion
• Misfire conditions related to weak spark output
• Reduced fuel economy from degraded ignition performance
• Emissions issues tied to aging secondary ignition components

Installation Notes

Verify the vehicle’s required heat range, thread diameter, reach, and seat type before installation. Check the gap against the vehicle specification even though this plug is pre-gapped at 0.8 mm. Follow the service manual for torque and removal procedures, especially on applications such as 2004 Mercedes-Benz E500, where two spark plugs are required per cylinder, and 1990-1991 Chevrolet Corvette, where aluminum head notes apply.
