2011 Chevrolet Caprice Spark Plugs

Genuine GM spark plugs for the 2011 Chevrolet Caprice, at wholesale prices. Heat range and gap are specified per engine, and GM has revised plug part numbers mid-generation on several engines. The Police Patrol Vehicle sold from 2011 through 2017 was a Holden built rear-drive sedan, unrelated to the earlier B-body Caprice.

When to replace

Misfires under load, rough idle, or a drop in fuel economy. On a full-size car, option packages divide this group more than the model year does.

What sets these apart

• 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.
• OEM, not lookalike. With spark plugs the difference shows up on installation day, not in the photo.

Avoiding the wrong part

Genuine GM parts carry the factory part number, so supersessions are documented rather than guessed at. Run your VIN first. One vehicle can list several nearly identical parts and only one is correct. Because we ship centrally, a heavy part costs less delivered here than from a coastal seller.
