2010 Chevrolet Express 4500 Spark Plugs

Genuine GM spark plugs for the 2010 Chevrolet Express 4500, at wholesale prices. Heat range and gap are specified per engine, and GM has revised plug part numbers mid-generation on several engines. Cutaway chassis rated above the 3500 for box and shuttle bodies.

When to replace

Misfires under load, rough idle, or a drop in fuel economy. On a commercial vehicle, trim and package content split these part numbers in ways a diagram will not show.

The case for genuine GM

• Ships from Dallas. Spark Plugs ordered by 3pm Central go out the same business day.
• Straightforward returns. No restocking games on spark plugs that did not fit.
• GM stands behind it. The spark plugs warranty comes from the manufacturer, not from us.

Avoiding the wrong part

When a component is superseded, GM documents why. That history is worth having when something failed early. Two vehicles off the same line in the same week can take different parts. The VIN is how we tell. Most orders leave the same day. Oversized and freight items take an extra day to crate.
