Spark plug cap 2007 Chevy silverado v8 4.8L?

The 2007 Chevy Silverado 4.8L V8 uses a standard spark plug wire and cap system. There isn't one specific part number for the cap because it depends on the specific wire set used. The caps are usually sold individually or as part of a complete wire set.

To find the correct spark plug cap, you need to do one of the following:

* Check your existing wire: The cap itself might have a part number molded into the plastic.

* Use a parts website: Websites like AutoZone, Advance Auto Parts, Napa Auto Parts, or Amazon allow you to search by vehicle year, make, model, and engine. Enter the details of your 2007 Chevy Silverado 4.8L V8 and search for "spark plug wires" or "spark plug wire set". The individual cap information may or may not be listed separately, but buying a new set is usually recommended rather than replacing individual caps unless you have a very specific reason.

* Visit a local auto parts store: They can look up the correct spark plug wires and caps using your VIN number.

Important Note: If you're replacing a single spark plug cap, consider replacing all of them at the same time for consistency and optimal engine performance. Worn or damaged spark plug wires can cause misfires and other engine problems.
