High Performance Ignition Coil for Chevrolet Caprice (2014-2017) 6.0L

High-Output Ignition Coil Set for 2014-2017 Chevrolet Caprice (L77 / Zeta)

Direct Replacement Upgrade: This complete set of eight UF414 ignition coils directly replaces the aging factory units to restore spark energy, prevent misfires under heavy load, and support optimal combustion efficiency for the 6.0L V8.

The Stock Caprice Ignition Weakness

The factory GM Gen IV LS-based ignition coils are reliable under normal conditions but degrade significantly due to prolonged engine bay heat soak. The Caprice, often subjected to extensive idling and high-stress driving cycles, accelerates the thermal breakdown of the internal epoxy potting. Over time, this leads to primary winding resistance changes and high-voltage leaks. Symptoms manifest as intermittent hesitation, rough idle, unburned fuel triggering oxygen sensor codes, and high-RPM misfires, particularly when cylinder pressures increase due to aging spark plugs.

The Engineering Solution

Upgrading to these heavy-duty UF414-spec replacement coils mitigates thermal degradation and restores maximum spark output. Engineered to exceed OEM specifications, these coil packs utilize high-grade copper internal windings and upgraded magnetic cores to deliver a stronger, more consistent spark duration. The external housing features a reinforced dielectric epoxy structure designed to resist the extreme ambient temperatures of the Zeta platform engine bay. By ensuring complete air-fuel mixture ignition, this 8-pack upgrade stabilizes idle quality, improves throttle response, and provides the reliable spark intensity required for the L77 V8 to perform optimally.
