Granatelli Malevolent 85KV Coil Packs – GM LT-Series (C7/C8 Corvette, Gen 6 Camaro) – Set of (8) always ship for FREE.
Want more ignition headroom for your LT1 or LT4 without turning your engine bay into a science project? Granatelli’s 85KV Malevolent coil packs deliver nearly double the voltage of the factory coils, giving your LT-platform more spark energy, cleaner combustion, and the stability you need as boost and RPM go up.
These are a direct plug-and-play upgrade for 2014+ GM LT-series cars (C7/C8 Corvette and 6th-gen Camaro), so you get real performance gains without wiring hacks, custom brackets, or warranty nightmares.
Why Step Up to Malevolent Coils?
The stock LT coils work fine on a mild setups—but once you add boost, E-blends, and higher cylinder pressure, you start asking more from the ignition system than GM designed it for. The Malevolent coils answer that with:
85,000 volts of output – roughly twice the voltage of typical OE-style coils for a stronger, more consistent spark at high load.
Improved combustion efficiency – better spark energy helps light off rich mixtures and high cylinder pressures, improving throttle response and idle quality.
Real horsepower gains – independent testing published in LSX Magazine has shown gains of ~6–8 hp on otherwise stock vehicles, with up to ~12 hp on bolt-on cars and as much as ~18 hp on high-boost, forced-induction builds. Your results may vary.
OEM-style reliability – direct replacement design, factory connectors, and no ECU trickery required. Plug them in, clear the bay, and go.
CARB EO D-471-4 – emissions-compliant for many late-model applications (check local regulations).
Compatible with Granatelli 0-ohm wires – maximize total ignition performance when used with their matching wire sets along with Brisk’s Silver Racing Spark Plugs found HERE.
If you’re leaning on your LT1/LT4—and especially if you’re on boost and ethanol—these coils give you extra margin before spark blowout becomes the weak link.
Color & Aesthetic Options – Match Your Engine Bay
Performance doesn’t have to be boring. The Malevolent LT coils are available with red, black, or blue coil bodies, so you can match the look of your build instead of settling for generic black plastic. Note; you are able to remove the stickers from the coil pack bodies if you prefer a non-branded color option.
Pair them with Granatelli’s 0-ohm high-performance plug wire sets, available in coordinating colors, to tie the whole engine bay together—clean routing, bold color, and a visual cue that your ignition system is as serious as the rest of the car.
About Granatelli Motor Sports
Granatelli Motor Sports is built on a racing legacy that goes back more than 70 years of Granatelli family involvement in American motorsports.
Founded in 1989 by J.R. Granatelli and headquartered in Oxnard, California, the company designs, engineers, and tests performance parts in-house—from mass air sensors to ignition coils and wire sets—focused on real gains on the dyno and at the track, not just catalog numbers.
That lineage shows up in the Malevolent coil line: they’re built to survive real abuse, from street cars to serious competition builds, while delivering the spark energy modern high-output LT engines demand.
Fitment – GM LT-Series Cars
C7 Corvette (2014–2019)
Stingray / Z51 (LT1)
Grand Sport (LT1)
Z06 (LT4)
C8 Corvette (2020+)*
Stingray and higher trims using LT-series coil architecture (verify per build)

ZL1 / ZL1 1LE (LT4)
Note: These are designed for car applications using GM’s LT-series V8 coil layout. Not intended for truck/SUV coil locations. Always verify fitment for your specific year/trim before ordering.
If your LT1 or LT4 build is starting to outgrow the stock ignition—or you just want a sharper, more responsive car with a cleaner idle and a matching coil/wire combo—these Granatelli Malevolent 85KV coils are a smart upgrade.
Add them to your cart, pair them with matching Granatelli performance wires, and give your LT the spark energy it deserves. oh, and don’t forget these always ship for FREE.
