2012 GMC Canyon Spark Plugs

Genuine GM spark plugs for the 2012 GMC Canyon, at wholesale prices. Heat range and gap are specified per engine, and GM has revised plug part numbers mid-generation on several engines. GMT355 through 2012, the 31XX mid-size from 2015 to 2022, and a new generation from 2023. No 2013 or 2014 model years.

How you know

Misfires under load, rough idle, or a drop in fuel economy. On a mid-size pickup, two trucks with the same badge can take different parts once cab style and drivetrain are accounted for.

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.

Confirming fitment

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.
