2010 Chevrolet Impala Spark Plugs

Genuine GM spark plugs for the 2010 Chevrolet Impala, at wholesale prices. Heat range and gap are specified per engine, and GM has revised plug part numbers mid-generation on several engines. W-body through 2013 and the Epsilon II from 2014 to 2020.

Symptoms to look for

Misfires under load, rough idle, or a drop in fuel economy. On a full-size car, engine option is the main split here, and it runs deeper into the group than most people expect.

Why buy OEM here

• Wholesale pricing. Most spark plugs numbers land well below dealer list.
• No aftermarket substitutes. These are GM spark plugs, not OE-style equivalents.
• We catch the wrong part before you do. VIN verification is free on every spark plugs order.

Ordering correctly

OEM components carry GM warranty coverage, which is usually worth more than the price gap on the invoice. If you are unsure which version you have, give us the VIN and our specialists will confirm fitment. Stock moves out the door the day you order it, assuming you beat the mid-afternoon cutoff.
