This iridium gold spark plug provides a dependable ignition solution for vehicles such as Buick, Chevrolet, and Hummer. Designed as a direct replacement for the 41-962 type, it helps restore engine performance and fuel efficiency. The iridium gold flame electrode material offers improved electrical conductivity and long-term resistance to erosion, making it a practical choice for routine maintenance. Each plug is sold individually, ensuring you only pay for the exact number needed for your engine.

Features and Construction

Built to meet standard spark plug specifications, this component focuses on reliable ignition and straightforward fitment. Its construction prioritises durability and consistent performance under normal driving conditions.

Material and Build

The centre electrode uses an iridium gold flame alloy, which combines the high melting point of iridium with the conductivity of gold. This material choice helps maintain a stable spark over extended periods, reducing the need for frequent replacements. The plug body is constructed to standard dimensions for a secure, leak-free seal.

Size and Practical Fit

With a 41-962 fitment type, this spark plug matches the thread size, reach, and hex size required by many General Motors (GM) family engines. It installs using a standard spark plug socket and does not require specialised tools, making it suitable for both professional mechanics and DIY enthusiasts.

Uses and Placement

This spark plug is intended for use in ignition systems of petrol engines. Its design supports daily driving, towing, and other common automotive applications where consistent spark delivery is essential.

Event or Professional Use

For automotive service centres and workshops, this plug offers a reliable replacement option for routine tune-ups. Its compatibility with multiple GM-based models simplifies inventory management, as one part number serves several vehicle lines.

Everyday Home Use

Car owners performing their own maintenance can install this plug without specialist equipment. Replacing worn spark plugs with a fresh iridium gold unit can help restore smooth idling, reduce misfires, and improve throttle response in older vehicles.

Benefits and Buying Value

Choosing this iridium gold spark plug brings practical advantages in terms of longevity and ignition consistency. It serves as a cost-effective maintenance part that supports engine health over thousands of miles.

Reuse and Low Maintenance

The iridium gold electrode material is more resistant to erosion than standard copper or nickel alloys. This means fewer replacements over the life of the vehicle, reducing long-term maintenance costs and effort.

Why Choose This Product

This plug delivers a known, proven fitment for a wide range of GM-family engines. Its material composition and standard dimensions make it a straightforward, no-compromise replacement part for keeping your engine running reliably day after day.
