Iridium Gold Spark Plug 41-962 Replacement for Buick Chevrolet Hummer Vehicles

This Iridium Gold Spark Plug is a direct replacement part for a range of GM-platform vehicles, including Buick, Chevrolet, and Hummer models. Designed to replace worn or fouled spark plugs, it uses an iridium gold flame electrode to maintain a strong, consistent spark. Whether you are performing routine maintenance or troubleshooting a misfire, this single plug provides a straightforward fix for compatible engines.

Features and Construction

The spark plug's construction centres on the iridium gold flame electrode, a material chosen for its resistance to wear and corrosion under high-temperature combustion conditions.

Electrode Material

The iridium gold flame electrode delivers a concentrated spark that helps ignite the air-fuel mixture reliably. Iridium alloys are known for their high melting point and longevity in demanding engine environments, though exact performance data is not provided.

Compatibility and Fit

This spark plug is listed as suitable for Buick, Chevrolet, and Hummer vehicles, among others. It carries the part number 41-962, which cross-references to many GM applications. Always verify compatibility with your specific vehicle year and engine code before installation.

Replacement Use

Intended as a single replacement unit, this spark plug can be used to replace one faulty plug or as part of a full set. Standard installation practices apply: check gap, thread, and torque specifications.

Uses and Placement

The spark plug is designed for internal combustion engines in cars, SUVs, and light trucks that originally specify the 41-962 part.

Vehicle Applications

Common applications include Buick LeSabre, Chevrolet Silverado, Hummer H2, and other models from the GM family that share the same engine platform. It replaces OEM and aftermarket plugs with the same cross-reference number.

Maintenance Intervals

Spark plugs are typically replaced every 30,000 to 100,000 miles depending on manufacturer recommendations. This iridium plug is suitable for standard replacement intervals but always follow your vehicle's service schedule.

Installation

Install using a spark plug socket and torque wrench. Do not over-tighten. Ensure the electrode gap matches your engine's specifications before installation.

Benefits and Buying Value

Choosing a replacement spark plug with a quality electrode material helps restore engine performance and fuel efficiency without unnecessary expense.

Reliable Spark

The iridium gold electrode resists fouling and erosion, helping to maintain consistent ignition over the plug's service life.

Easy Compatibility

With the clear 41-962 designation, you can quickly identify that this plug fits your vehicle without guesswork.

Single-Unit Purchase

Buying a single plug allows you to replace only the faulty unit, saving money compared to purchasing a full set when only one is needed.
