2014 GMC Yukon Spark Plugs

Genuine GM spark plugs for the 2014 GMC Yukon, 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.

Symptoms to look for

Misfires under load, rough idle, or a drop in fuel economy. On a full-size SUV, vehicles with air ride or magnetic dampers take different parts from those on the standard setup.

Buying OEM, briefly

• Factory warranty. Genuine spark plugs carry GM coverage aftermarket cannot match.
• Dealer parts, not dealer prices. Compare our spark plugs pricing against a counter quote.
• Genuine GM only. Every spark plugs listing carries the original factory part number.
• Fitment checked by a person. Send the VIN and we verify the spark plugs before the box leaves.
• Central shipping origin. Dallas keeps spark plugs transit times short nationwide.

Ordering correctly

Factory parts are built to the tolerances the vehicle was engineered around, not copied from a worn sample. A photo is rarely enough to order from. The VIN takes seconds and removes the guesswork. Freight is quoted at what it actually costs, not inflated to subsidize a headline discount.
