Denso 4510 Spark Plug

Denso Platinum TT 4510 Spark Plug

Denso Platinum TT 4510 is a tapered-seat spark plug built for secondary ignition service in a wide range of Ford, Chevrolet, GMC, and related applications. Its twin-tip electrode layout is engineered to promote faster flame travel for more complete combustion, helping maintain consistent ignition performance in older V8 and V6 engines.

The Platinum TT line focuses on stable spark delivery, durable electrode materials, and OE-style fitment. With a platinum center electrode tip, nickel ground electrode core, copper center core, and 5000 ohm resistance, this plug is built for dependable ignition control in vehicles such as the Ford F-150, Chevrolet Camaro, and GMC Yukon.

Key Features

• Twin-Tip ground electrode design for quicker flame propagation
• Platinum center electrode tip for long service life
• Copper center core and nickel ground core for efficient spark transfer
• 5000 ohm resistor for ignition noise suppression
• Pre-gapped at 1.0 mm for direct service use
• Tapered seat, 14.00 mm thread diameter, 11.60 mm reach, 16.0 mm hex
• Manufacturer heat range 20

Product Details

Denso Platinum TT 4510 uses a Titanium Enhanced Twin-Tip ground electrode configuration to support a more efficient burn event than conventional single-tip designs. That matters in engines that need stable ignition under load, idle, and stop-and-go driving. This spark plug cross-references DENSO Auto Parts PTF20TT for the same application.

Compatible With applications including 1984-1996 Ford F-150, 1987-1995 Chevrolet Camaro, and 1993-1997 GMC Yukon, this part number 4510 is also listed across many GM, Ford, Chrysler, and Dodge interchange references. The Platinum TT design is a practical OE-style choice for drivers servicing aging trucks, vans, SUVs, and performance cars.

Common Issues This Part Addresses

• Rough idle caused by worn spark plug electrodes
• Hard starting from weak or inconsistent ignition output
• Misfire conditions related to degraded secondary ignition components
• Reduced combustion efficiency from excessive plug wear
• Ignition noise concerns in resistor-equipped systems

Installation Notes and Tips

Verify thread diameter, reach, seat type, and heat range before installation. Denso Platinum TT 4510 uses a tapered seat and 14.00 mm thread diameter, so correct cylinder head match is essential. Check the pre-gap against the engine specification before use, and inspect ignition wires, coils, and distributor components at the same time to avoid repeat misfire concerns.

For fitment research, this spark plug is listed for vehicles such as the Ford Bronco, Chevrolet S10, GMC Safari, and Pontiac Trans Sport across the model years shown in the fitment data. Confirm the exact engine application before ordering.

Quality Assurance

Denso designs the Platinum TT line around durable electrode materials and controlled spark performance for long-term ignition service. The platinum tip, copper core, nickel ground electrode, and resistor construction support consistent operation in demanding daily-driver and light-duty truck applications.
