Ignition Coil & Spark Plug for Cadillac CTS-V (2006-2016) Escalade ESV EXT (2007-2016) V8 (Round Style)

High-Energy Ignition Coil & Spark Plug Set for 2006-2016 Cadillac CTS

Direct replacement ignition overhaul: Replaces degrading factory coils, plugs, and wires to deliver 20% more spark energy, resolving high-RPM misfires and restoring peak combustion efficiency in your V8-powered Cadillac.

The Stock CTS-V Ignition Weakness

The factory GM LS and LT series ignition coils are highly susceptible to thermal degradation over time. Under continuous heavy engine loads and extreme under-hood temperatures, the OEM internal epoxy potting breaks down, increasing secondary electrical resistance. This heat soak causes spark blowout during aggressive acceleration or under forced induction, leading to cylinder misfires, sluggish throttle response, and unburned fuel entering the exhaust stream.

The Engineering Solution

This comprehensive ignition kit addresses factory shortcomings by utilizing high-purity copper wiring and an upgraded internal epoxy construction to handle severe heat cycling. Engineered specifically for the round-style (UF414/D514A) ignition systems, these direct plug-and-play coils deliver up to 32,000 maximum voltage with a 61:1 turns ratio. By producing 20% more discharge energy than OE equivalents, this kit guarantees a stronger, more consistent spark arc. The included OE-spec spark plugs and low-resistance 748UU plug wires ensure minimal voltage drop from the coil pack to the combustion chamber, maintaining precise ignition timing under maximum engine load.
