MAS Set of 5 Ignition Coil Pack Chevy Colorado Trailblazer Condition

Condition. This listing is for a MAS set of 5 ignition coil packs compatible with Chevrolet Colorado, Chevrolet Trailblazer, GMC Canyon, and Hummer H3. The photo shows one representative coil from the set of five units included.

Overview

MAS aftermarket ignition coil packs are engineered as direct-fit replacements for the coil-on-plug ignition systems found on compatible GM inline-5 and inline-6 platforms. Running at 12 V, each coil in this set is built to deliver reliable spark energy to keep your engine firing efficiently. Compatible equipment makes include Chevrolet, GMC, and Hummer, covering models such as the Colorado, Trailblazer, Canyon, and H3. Replacing a full set of coils at once is the recommended approach when diagnosing misfires, rough idle, or poor fuel economy, ensuring consistent ignition performance across all cylinders.

Each coil features a robust black polymer boot and cap assembly with a brass-toned metal core visible in the photo — the hallmark construction of the coil-on-plug design used on these GM applications. The mounting flange and integrated spark plug boot allow for straightforward installation with standard hand tools.
