The X4XZ UF680 ignition coil kit paired with LTR6GP8 double iridium spark plugs is engineered for 2.0L GM inline-four engines, spanning Buick, Cadillac, Chevrolet, and GMC lines. This kit aligns with common replacement part standards, offering a cohesive upgrade path that emphasizes reliability and smoother operation across multiple models.

Quality and design at a glance

Quality materials and thoughtful design focus on consistent spark delivery and durable performance under varying conditions. The stainless-steel spring adds lasting strength, while the ferrite noise suppressor helps minimize radio frequency interference. A heat-resistant thermoplastic coil connector promotes a secure, reliable connection even during heat cycles, supporting stable high-voltage transfer to the plugs.

• Compatibility across Buick, Cadillac, Chevrolet, and GMC models with 2.0L engines, including popular Envision, Regal, ATS, CTS, Camaro, Equinox, and Terrain variants.
• Premium construction features stainless-steel spring, ferrite noise suppressor, and a thermoplastic coil connector for durability and reliable electrical transfer.
• Double iridium spark plugs offer a long service life (up to about 100,000 kilometers) with consistent sparks under different driving conditions.
• OE-compatible references UF680 and 94489 help align with common replacement part catalogs; designed for straightforward installation.

Real-world benefits you may notice

With upgraded ignition components, you may experience easier cold starts and a steadier idle. In city traffic or on highway runs, a more consistent spark delivery can contribute to smoother acceleration and responsive throttle input. While results vary by vehicle and usage, the kit is designed to support reliable operation and maintenance of ignition timing.

• Potential for smoother idle and more stable engine performance during start-up.
• Reduced misfires and steadier response under varying loads and temperatures.
• Durable construction resists heat and thermal cycling for long-term reliability.
• Noise suppression helps minimize interference while transferring high voltage to the spark plugs.

Package contents and installation notes

The kit includes four UF680 ignition coil packs and four LTR6GP8 double iridium spark plugs. Please note that an instruction manual is not included; basic mechanical skills and standard replacement tools are typically sufficient for installation.

Compatibility and cross-reference: UF680 and 94489 are listed as part numbers to help confirm cross-compatibility with existing parts catalogs. This bundle is intended to cover a broad range of GM 2.0L I4 models produced between 2013 and 2021, offering a unified upgrade path for multiple vehicles.
