2010 GMC Sierra 2500 Spark Plugs

Genuine GM spark plugs for the 2010 GMC Sierra 2500, at wholesale prices. Heat range and gap are specified per engine, and GM has revised plug part numbers mid-generation on several engines. Catalog listing covering the light duty 2500 through 2004 and continuing as an alias for the 2500 HD.

When to replace

Misfires under load, rough idle, or a drop in fuel economy. On a heavy duty pickup, single or dual rear wheels, gas or diesel, and cab configuration divide this group more than the model year does.

Why order factory

• VIN verified fitment. We confirm the spark plugs number against your vehicle before it ships.
• Same day dispatch. Order spark plugs by mid-afternoon and it leaves our warehouse that day.
• Returns without a fight. We would rather fix a spark plugs order than argue about it.
• Covered by GM. On spark plugs that coverage is worth more than the price gap.
• Real wholesale. The same spark plugs your dealer sells, at a fraction over our cost.

Avoiding the wrong part

The factory number ties back to GM engineering records, which is something no aftermarket catalog can offer. Give us the number stamped on the old part and we will trace what it superseded to. Same day shipping on in stock items, direct from one of the largest GM parts warehouses in the country.
