MAS 5-Pack Ignition Coil Set for 2004-2006 Colorado/Canyon/H3/I-350/I-370 (3.5L/3.7L) UF303/C1395/E255 Replacement

MAS 5-Pack Ignition Coil Set for select GM-based engines

Upgrade your ignition system with the MAS Set of 5 Ignition Coil Packs, a direct-fit replacement designed for GM-based engines. This five-pack aligns with UF303, C1395, and E255 equivalents, offering a cohesive upgrade across all cylinders and a balanced electrical supply. The coils feature a robust build and a precise electrical interface intended for straightforward installation, reducing the guesswork of a mixed parts replacement. In real-world use, you may notice smoother throttle response and steadier engine idle as old coils age and drift in spark energy.

Note: Please verify compatibility before purchase using the year, make, model dropdown and the listed interchangeable part numbers to ensure a precise match for your vehicle.
