Comparing Our ACDelco Spark Plug Models
This category features two standout products tailored to different needs, helping you choose based on your engine requirements.
ACDelco 41-962 Professional Platinum Spark Plug
The 41-962 is a premium aftermarket choice with a platinum fine-wire center electrode and platinum pads on ground electrodes. This double-platinum design resists wear, providing consistent performance in a wide range of applications. It's perfect for vehicles demanding high-mileage dependability without the premium cost of iridium. Install these for smoother idling and better cold starts, especially in fleet or high-use scenarios.
ACDelco GM Original Equipment 41-108 Iridium Spark Plug
As a genuine GM OE part (12681658 cross-reference), the 41-108 uses iridium for an exceptionally small electrode diameter, enabling a more focused spark. This results in superior ignitability, ideal for modern direct-injection engines. Choose this for factory-level precision in GM trucks, SUVs, and sedans, where longevity and efficiency are paramount.
Platinum suits budget-conscious upgrades with solid all-around performance, while iridium is the go-to for OEM restoration or maximizing fuel economy. Both integrate seamlessly into your Replacement Parts maintenance routine.
Common Use Cases for ACDelco Spark Plugs
These plugs shine in routine tune-ups, addressing symptoms like rough idling, poor acceleration, or decreased MPG. They're commonly used in GM vehicles from the 2000s onward but fit many universals. For performance builds within the Spark Plugs family, pair with quality wires. Harsh conditions like towing or extreme temperatures highlight their robust construction.
