Ignition Coil & Spark Plug for GMC Envoy XL XUV (2005-2009) V8

Ignition Coil & Spark Plug Kit for 2005-2009 GMC Envoy V8

Look at the coils on your engine and pick the matching style before you order. These Envoy V8s use two different coil shapes that are not interchangeable. This kit restores spark timing, helps eliminate misfires, and includes coils, spark plugs, and plug wires in the style you select.

Choose Square or Round

Open the hood and compare the coils already on your engine to the photos on this page, then choose that style from the dropdown:

• Square style (UF413 / D510C / GM 12611424, also 12570616): a boxy, flat-sided coil body.
• Round style (UF414 / D514A / GM 12573190): a cylindrical coil body.

Both styles show up on the same model years, so year and engine alone are not enough. The two styles use different coil bodies and may use different harness connectors. The wrong style will not fit.

What This Kit Does

This complete ignition kit replaces weak or failing factory coils, spark plugs, and plug wires. The coils use copper windings and high-dielectric epoxy to resist under-hood heat soak and deliver a strong, consistent spark. Once you select the correct coil style, the kit is a direct plug-and-play set for the vehicles listed below.

Common Questions

How do I know which style to order?
Look at the coils on your engine and choose Square or Round to match that shape. Use the comparison photo on this page. Do not order by year or engine alone.

Will this fit my 2005-2009 Envoy V8?
Yes, if you pick the matching coil style. Some early 5.3L GMT360 vehicles used an older D585 coil that is not this kit; confirm the coil body on the engine before ordering.

What is included?
A complete V8 set of the selected-style ignition coils, spark plugs, and spark plug wires.
