spark plug socket, ratchet, socket extensions, spark plug gap tool, wire strippersIn this video I replaced the spark plugs on my 2022 Chevy Silverado LTD 2.7L Turbo Gas 4 Cylinder. GM recommends 60,000 mile spark plug intervals. I was a little late on this truck, with almost 95,000 miles on it. This process should be similar on all 2019+ 2.7L turbo gas engines including the 2022.5+ refreshed High Output TurboMax models. This may also apply to 2023+ Chevy Colorado and GMC Canyon with the new 2.7L TurboMax engine variants.
