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
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.

BRISK Racing Silver Spark Plugs
Perhaps like you, I did not pay much attention to my spark plugs at first, but after talking with a few knowledgeable tuners, and other high HP enthusiast, the brand BRISK came up over and over again, so we decided to take a look.
After reading all of the technical bits below from Brisk it made sense to upgrade during the next oil change and we have not looked back since.
At our power level, we want to use the best spark plug available as cheap insurance to help us stay reliable, and make the most power possible.
Modified LT4’s demand ignition components that can withstand extreme conditions and deliver maximum efficiency, which is why Brisk Racing Silver Spark Plugs are an ideal choice for our supercharged cars. These plugs feature a silver center electrode, known for its superior thermal and electrical conductivity compared to traditional materials like copper or platinum. This results in a stronger, more consistent spark, improved throttle response, and more efficient combustion—all critical for modified, boosted and high-revving engines. Additionally, the silver construction resists fouling and maintains performance even under high-stress driving conditions, making them especially suited for the LT4. By using Brisk Racing Silver Spark Plugs, drivers can ensure their engines operate at peak performance with enhanced power, fuel efficiency, and reliability.
Running a colder spark plug helps improve combustion stability and reduce the risk of pre-ignition or detonation under increased cylinder pressures and elevated combustion temperatures. Colder plugs have a shorter insulator nose and dissipate heat more quickly to the cylinder head, keeping the firing tip cooler. This is crucial on LT4 applications where forced induction significantly raises the thermal load on the engine. By controlling plug tip temperatures, colder plugs help maintain reliable spark performance, prevent misfires, and support consistent power delivery—especially during sustained high-boost conditions.
From the Brisk website;
Brisk Silver Racing Spark Plugs have a smaller diameter silver core and conventional open spark hook type earth electrode give an outstanding performance in igniting high octane fuel mixture associated with alternative fuels like CNG, LPG, Propane, E85 blend, Alcohol, LNG, Race Fuels and Nitro.
Silver metal is the single best material for a spark plugs core electrode, as it can dissipate heat fast, resulting in overall lower spark plug temperature and a more powerful spark. Silver is the best conductor of any metal! It conducts 560% more electricity & 481% more heat than Platinum, and 276% more electricity & 177% more heat than Iridium.
The stronger the spark the faster and better the flame front and flame speed giving smother higher RPM range in engines.
The BRISK Silver Racing spark plug works well with most aftermarket and OEM ignition systems form simple coil and distributor through electronic ignition and powerful direct ignition systems found on modern port and direct injection performance engines.
Features
Fires properly even if fouling occurs, common standard plugs failure.
Silver centre electrode, best thermal (heat) & electrical conductor.
Lower voltage requirement for safe operation.
Reduces wear on coil, leads and other ignition parts.
1.5 mm Silver Wire Centre Electrode
Applications
Methanol, ethanol, CNG, LPG, Propane, E85 blend, Alcohol, LNG, Race Fuels, Nitro, Nitrous.
Old vehicles with weaker ignition systems and/or excessive oil consumption.
High RPM race engines with short time for ignition coil saturation.
Naturally aspirated or forced induction applications
Standard and high compression engines
High octane or hard ignition fuels.
Service Life
15-18k miles
50 hours racing
Brisk Silver Racing spark plugs have helped Tim Lynch and Steve Petty to keep the A/F mixture lit and set 4 New World Records since they started using them in their extreme 3,000+ HP 6.6sec @ 223.5mph Twin Turbo 10.5 Outlaw Mustang, and can do the same for you… but without the Mustang of course, HAHA.
Note; we sell these spark plugs individually, because when I purchase spark plugs I always keep 1-2 extra on the shelf just incase I have an issues one day, or I damage one… and I don’t want to order an entire set of 8. Anyway, that is why we sell them this way. That said, we do recommend ordering 1-2 extra for closet stock.
For Spark Plug gap, we always suggest you ask and follow your tuners advice. Don’t like your tuner? Then let me know and I will ask mine! For reference, I run a .024” gap on my 800+ rwhp car with great results. We also suggest using a small amount of anti-seize on the threads during install
OPTIONS; note we offer the RR14S which is 1-step colder than stock and the RR12S which is 2-steps colder. We recommend the RR14S plug between 550-750rwhp and then the RR12S for 750-1,000rwhp. For reference, I used the RR14S when I was at 660rwhp and switched to the RR12S after I was past 770rwhp based on my tuners recommendation.
