Overview

This LCWRGS Set of 6 ignition coil packs and spark plugs is built for the 4.2L V6 engines found in popular SUVs like the Chevy Trailblazer, GMC Envoy, Buick Rainier, and Isuzu Ascender from model years 2006 through 2009. Replacing multiple aging components at once can help restore a more confident start and smoother operation across the engine’s six cylinders. The kit includes 6 coils and 6 plugs, designed to align with the OE replacement parts UF497, C1558, E997, IC577, and 12596547, making it a direct-fit option for a broad range of 4.2L V6 vehicles.

Premium engineering for reliable ignition

• Premium copper wire and high dielectric epoxy are used to promote solid electrical connectivity and durable performance.
• Direct OEM design aims to match the form and function of the original components for easy installation.

What’s included and how it helps

• 6 ignition coil packs and 6 spark plugs provide a complete replacement set in one package.
• Coils are designed to deliver consistent energy to each cylinder, potentially supporting even firing and smoother engine response.

Performance notes and real-world use

Over time, factory coils and plugs can degrade, which may lead to hesitations or misfires. This kit markets up to 15% more energy than OE coils in its design language, which could translate to crisper ignition events and improved throttle feel in everyday driving. Results can vary based on vehicle condition, maintenance history, and driving conditions.

Installation, warranty, and support

• Direct fitment for 2006–2009 4.2L V6 Trailblazer, Envoy, Rainier, and Ascender models.
• Includes a 24-month warranty and responsive customer support to help address installation questions or concerns.

Whether you’re restoring reliability for a daily driver or prepping for long trips, this LCWRGS kit offers a coordinated set of coils and plugs designed to work together as a replacement package. Consider pairing with a full tune-up for best overall results, and review compatibility with your exact vehicle VIN if you’re unsure about fitment.
