Product Details

NGK’s Laser Platinum Spark Plug line is built around OE replacement requirements, with materials and dimensions selected to match factory-style ignition performance. This plug uses a platinum tip on the center electrode for durability, while the copper core helps support heat transfer and consistent operation. The tapered seat and standard electrode configuration make it a direct-service choice for many vehicles that call for a 0.044-inch gap, including select Ford F-150, Ford F-250 Super Duty, and Chevrolet Equinox applications. The NGK 3587 is also referenced in cross-application listings such as Bosch HR7MPP302X and Anchor 3587 for the same application.

Compatible vehicle coverage includes long-tail searches such as 2010-2017 Chevrolet Equinox spark plug replacement, 2012-2017 Ford F-250 Super Duty Laser Platinum spark plug, and 2007-2015 Mazda CX-9 OE replacement spark plug. The NGK 3587 also appears in fitment for Buick Enclave, Cadillac CTS, GMC Acadia, and Chevrolet Traverse models across multiple years.

Common Reasons to Replace

• Hard starting or extended crank time
• Rough idle or intermittent misfire
• Reduced fuel economy from worn ignition components
• Loss of throttle response under load
• Service interval maintenance on OE-recommended applications

Installation Notes

Confirm the vehicle-specific gap before installation; several listed applications require 0.044 inches, while some older Suzuki and Cadillac applications call for 0.039 or 0.040 inches. Check the service information for your exact engine, especially on dual-plug Ford Super Duty and F-150 applications. Use proper spark plug removal and installation procedures to avoid thread damage and ensure correct torque.
