2010 Chevrolet Express 3500 Spark Plugs

Genuine GM spark plugs for the 2010 Chevrolet Express 3500, at wholesale prices. Heat range and gap are specified per engine, and GM has revised plug part numbers mid-generation on several engines. One-ton full-size van available as a passenger van, cargo van and cutaway.

When to replace

Misfires under load, rough idle, or a drop in fuel economy. On a full-size van, GVWR rating and upfit configuration split this group.

What sets these apart

• No hassle returns. If the spark plugs is not right, send it back.
• Warranty intact. OEM spark plugs keep coverage that an aftermarket part can void.
• Wholesale pricing. Most spark plugs numbers land well below dealer list.
• No aftermarket substitutes. These are GM spark plugs, not OE-style equivalents.

Avoiding the wrong part

A part validated on this vehicle behaves differently from one validated across a range of vehicles. Fitment questions are the one thing worth a phone call before checkout rather than after delivery. We ship from Dallas, which keeps transit times short across most of the country.
