Does a 2017 Chevy Colorado have spark plugs?

The 2017 Chevrolet Colorado does come equipped with spark plugs, as it’s powered by gasoline engines—and spark plugs are a critical part of the ignition system, responsible for firing up the air-fuel mixture to keep the truck moving. That year, the Colorado offered two gas engine options: a 2.5L inline-four and a 3.6L V6, both using conventional spark plug ignition with typically one plug per cylinder. Chevy recommends inspection or replacement every 60,000 to 100,000 km for optimal performance. (Quick note: Some modern diesel engines, like the Colorado’s available 2.8L Duramax, rely on glow plugs instead of spark plugs due to diesel’s compression-ignition design.) For owners, keeping up with spark plug maintenance helps avoid rough starts, sluggish acceleration, or wasted fuel. Opting for OEM-specified plugs or high-quality iridium/platinum alternatives can stretch replacement intervals. If your Colorado’s acting up—hard starts, misfires, or poor throttle response—check the plugs first. Pair that with basic upkeep like cleaning injectors or swapping the air filter, and you’ll keep the engine running sharp.
