2012 Chevrolet Suburban Spark Plugs

Genuine GM spark plugs for the 2012 Chevrolet Suburban, at wholesale prices. Heat range and gap are specified per engine, and GM has revised plug part numbers mid-generation on several engines. GMT900 through 2014, K2XX from 2015 to 2020, and the T1XX with independent rear suspension from 2021.

When to replace

Misfires under load, rough idle, or a drop in fuel economy. On a full-size SUV, suspension type and towing package split this group, and neither is visible from outside the vehicle.

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 Give us the number stamped on the old part and we will trace what it superseded to.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.
