Comparison Insights and Buying Advice

Choosing the best ignition coil for gmc sierra isn’t just about brand; it’s about matching the coil type to your engine’s generation. This is the single most critical factor in a successful installation.

First, identify your coil shape:

• Round Coils (UF-414/D585): These are used primarily on the older Gen 3 (1999–2006) and Gen 4 (2007–2013) V8 engines. If your truck is pre-2014, you likely need a round coil. The ENA and Round Ignition Coil Pack sets are excellent high-value choices for these applications.
• Square Coils (UF-742/UF-743): These are mandatory for the newest generation of V8 engines (L83, L86) found in 2014 and newer Sierra 1500s. If your Sierra is Gen 5, you must select the square design, like the OCPTY or A-Premium coils.

If you have a known single misfire (verified by a diagnostic tool), buying a single coil, such as the OCPTY (for modern trucks) or ENA D585 (for older trucks), is the most cost-effective fix. However, for vehicles with over 100,000 miles, replacing the entire set of 8, like with the A-Premium or ENA 8-pack, provides far greater long-term reliability and ensures consistent engine performance across all cylinders. Always check your vehicle’s specific production year and coil shape before finalizing a purchase.

Final Spark: Determining Your Top Pick

Based on performance, value, and specific vehicle generation, we can determine the top pick for different Sierra owners:

If you own a newer Gen 5 Sierra (2014+ 5.3L/6.2L): The A-Premium Ignition Coil Pack Set of 8 (Square Coil) is the top recommendation. It is engineered precisely for the sensitive electronics and performance demands of the latest V8 platforms, providing a high-quality, comprehensive replacement.

If you own a classic 2000-2006 Sierra 5.3L/6.0L: The ENA 1 Round Ignition Coil Pack (D585) is your go-to for single replacements. This D585 style offers the highest energy output required by those legendary early Gen 3 engines.

If you prioritize the best value 8-pack for 2007-2013 trucks: The Round Ignition Coil Pack Compatible with V8 4.8 5.3 6.0 Chevy Silverado… is highly recommended. It offers a reliable and complete solution for the common UF-414 round coil configuration without breaking the bank.

Best Ignition Coil For GMC Sierra FAQ

How do I know if my GMC Sierra needs new ignition coils?

The most common symptom of failing ignition coils is engine misfire, which usually presents as noticeable hesitation, sputtering, or jerking, especially under acceleration. You might also notice a reduction in fuel economy, a strong smell of raw gasoline from the exhaust (due to unburned fuel), or the illumination of the Check Engine Light (CEL), often with specific codes like P0300 (random misfire) or P030X (misfire on a specific cylinder).

Are the “Round” and “Square” ignition coils interchangeable on my Sierra?

No, the Round (UF-414 style) and Square (UF-743 style) coils are not interchangeable. They are physically different and have unique electrical resistance characteristics required by the different engine control modules (ECMs) used in the various generations of GM V8 engines. Using the wrong coil type can lead to poor performance, misfires, or even damage to the coil or ECM. You must confirm your vehicle’s generation (pre-2014 vs. 2014+) to choose the correct shape.

Should I replace all 8 ignition coils at once, or just the faulty one?

While you can technically replace only the failed coil, most experts recommend replacing all 8 if your truck is approaching or over 100,000 miles. Ignition coils experience consistent thermal wear, and if one has failed, the others are likely close behind. Replacing the full set ensures consistent spark strength across all cylinders and avoids repeated trips to the mechanic chasing intermittent misfires.

What’s the difference between the D585 coil and the UF-414 coil?

Both are round coils, but the D585 (UF262) is a larger, higher-energy output coil primarily used on early Gen 3 Vortec engines (2000–2006). The UF-414 is the standard round coil used on later Gen 4 engines (2007–2013). They are not interchangeable due to differences in mounting and electrical connections, so knowing your exact year/engine code is vital.

Do I need to replace spark plugs when installing new ignition coils?

It is highly recommended. If an ignition coil has failed, it may have put stress on the spark plug, or the old spark plug gap may be too wide for the new coil to operate efficiently. Installing new spark plugs ensures you get the maximum benefit and reliability from your new ignition coils.

What other components should I inspect when replacing the best ignition coil for gmc sierra?

Besides the spark plugs, always inspect the wiring harness connectors leading to the coils for signs of corrosion or cracking. Also, check the spark plug wires (if applicable, though most Sierras use coil-on-plug systems) and ensure all mounting bolts are tightened to the factory specification to prevent movement or vibration.
