2014 Chevrolet Suburban Spark Plugs

Genuine GM spark plugs for the 2014 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.

Buying OEM, briefly

• GM stands behind it. The spark plugs warranty comes from the manufacturer, not from us.
• Priced below the dealer. Spark Plugs at up to 40 percent off list, with no membership.
• Factory sourced. These spark plugs are built to GM's own drawing by the supplier GM contracted.
• No guessing. Our VIN lookup resolves the near-identical spark plugs numbers for you.
• Ships from Dallas. Spark Plugs ordered by 3pm Central go out the same business day.

Avoiding the wrong part

Original tooling means original fit, which matters most on anything that has to align with a neighboring part. Our VIN lookup is more accurate than any public catalog. Use it before you check out. In stock orders placed by 3pm Central ship the same business day from our Dallas warehouse.
