What is a Spark Plug Cross Reference?
A spark plug cross-reference is simply a way to find equivalent spark plugs from different manufacturers. This is useful if your preferred brand isn't readily available, if you need a replacement quickly, or if you want to compare prices from various suppliers. The cross-reference will show you the ACDelco part number and its equivalents from other brands like Bosch, NGK, Champion, and Denso.
How to Find ACDelco Spark Plug Cross References
Several methods exist for finding ACDelco spark plug cross-references:
-
Online Parts Databases: Many reputable online auto parts retailers (like AutoZone, Advance Auto Parts, etc.) offer comprehensive parts databases with cross-referencing capabilities. Simply enter your vehicle's year, make, model, and engine information, and then search for spark plugs. The results will often show ACDelco spark plugs and their equivalents from other brands.
-
Vehicle Owner's Manual: Your owner's manual should specify the recommended spark plug type for your vehicle. This information often includes the manufacturer's part number, allowing you to find the ACDelco equivalent through online databases or at an auto parts store.
-
ACDelco Website: While ACDelco might not directly offer a comprehensive cross-reference tool on their website, their parts catalog can help you identify the correct ACDelco part number based on your vehicle's information. This part number can then be used in online parts databases for cross-referencing.
