TRQ Ignition Coil Set Compatible with 17-21 GM V6 Engines - Direct Fit

In this review of the TRQ Ignition Coil Set, the bottom line is simple: this six-piece kit is aimed at owners of GM V6 3.6L and select 3.0L vehicles who need a direct-fit OE replacement without fuss. The reviewer found the set useful for routine ignition pack replacement because it mirrors OE reference 12666339 and comes as a complete kit of six coils, making it a practical choice for someone tackling all cylinders at once. Installation is straightforward for a competent DIYer, and value comes from replacing all coils with vehicle-specific parts at once.

Key Features

• Direct Fit: Designed to match OE dimensions and connectors so the coils install without modification on compatible GM V6 engines.
• OE Replacement: Built to the OE reference number 12666339 so buyers can expect compatibility with listed Chevrolet, GMC, Cadillac and Buick models.
• Complete 6-Piece Kit: Includes six ignition coils so the entire V6 ignition bank can be serviced in one job for consistent performance across cylinders.
• Vehicle Specific Fitment: The listing emphasizes checking vehicle compatibility, reducing the chance of purchasing the wrong coil for model years and engine types listed.
• Aftermarket Cross References: Supplied with common aftermarket numbers GN10889 and UF830 for easier parts lookup and comparison shopping.

Who It's For

This coil set is best for owners of 2016-2021 GM vehicles listed in the fitment such as Chevrolet Colorado, Camaro, Blazer, GMC Acadia, Canyon, and Cadillac XT5/XT6/CT5/CT6 and ATS/CTS with the specified V6 engines who want a direct-fit replacement that aligns with OE references. It is especially suited to DIYers and independent shops replacing all six coils to restore consistent ignition across the engine.

Those who should look elsewhere include owners of non-listed engine types or model years outside the fitment, and drivers who prefer OEM branded coils with manufacturer warranty coverage higher than typical aftermarket parts. Also, if only a single coil failed and an exact branded OEM part is required, verify options before buying.

Pros & Cons

Pros

• Good value: replacing all six coils at once reduces repeated labor and ensures matched performance across cylinders.
• Fit and installation: customers report the coils bolt on and plug in with minimal effort, matching OE connections.
• Performance improvement: several owners noted improved acceleration and elimination of misfire or hesitation once all coils were installed.

Cons

• Mixed longevity reports: some users report coil failures over time, so long-term reliability can vary between vehicles.
• Not a universal fit: buyers must carefully check the vehicle-specific fitment list to confirm compatibility.
