Unleash the full potential of your Gen 5 V8 with the EVIL ENERGY ignition coil series. Specifically engineered as a high-performance replacement for the OE UF743, this vehicle coil kit is precision-tuned for the advanced direct-injection demands of the LT platform. Whether you're pushing a 6.2L Supercharged Corvette or maintaining a high-mileage ignition coil Chevy Silverado, our coils deliver a massive 52,000V maximum voltage and 111mJ spark energy to ensure consistent combustion in every car ignition coil cycle.
Swap OE UF743 for EVIL ENERGY high‑output ignition coils and unlock maximum ignition energy and consistent performance. Straightforward installation, premium construction, and unbeatable value for street and performance use.

Engineered for improved combustion performance and a smoother driving experience, EVIL ENERGY ignition coils combine power, consistency, and durability for optimal engine operation.
Why EVIL ENERGY is the Premier Chevy ignition coil Choice:
- Elite Energy Output: With 111mJ of spark energy, our EVIL ENERGY ignition coil provides a significantly more intense fire than standard factory units, effectively preventing 'spark blowout' in high-compression 5.3 ignition coils applications.
- Engineered for Stability: This ig coil system is designed with a 71:1 turns ratio to match the precise dwell times of the Gen 5 ECU, ensuring a stable 1.8 mS spark duration for a smoother vehicle coil operation.
- Modern ig coil Reliability: Featuring a 0.53 ohms primary resistance, our car ignition coil is built to resist heat soak in the high-temperature engine bays of the GMC Sierra and ignition coil Chevy Silverado.
Feature:
- Boost Power & Fast Ignition: Specifically optimized for the high-pressure coil ignition system, our units deliver 111mJ of energy to ensure quick and efficient ignition. By upgrading to the EVIL ENERGY ignition coil, you can effectively increase horsepower and sharpen throttle response, maximizing the performance of your ignition coil Chevy Silverado.
- Reduce Jitter & Rough Idle: Eliminate the frustrating 'V8 stumble.' This premium ig coil solution minimizes engine vibration and unstable idle, providing the smoother acceleration and consistent stability required for a high-quality vehicle coil. It is the perfect fix for erratic idling in 5.3 ignition coils applications.
- Optimize Fuel Consumption: Enhance your combustion efficiency to stop wasting money at the pump. Our car ignition coil technology ensures more complete fuel burning, which reduces excess consumption and supports better fuel savings—an essential benefit for any daily-driven Chevy ignition coil setup.
- High-Temperature Resistant: Modern engine bays, especially in a GMC Sierra 1500, reach extreme temperatures. Our vehicle coil is built with premium, high-heat resistant materials and a 0.53-ohm primary resistance to ensure stable operation and prevent heat-soak failure in your coil ignition system.
- Stable & Durable Performance: Engineered with a heavy-duty 71:1 turns ratio, the EVIL ENERGY ignition coil offers dependable construction and a long service life. Whether for street use or towing, our car ignition coil provides reliable ignition performance that outlasts standard 5.3 ignition coils.


Resolve Critical Automotive Problems with EVIL ENERGY
Don't let a failing vehicle coil compromise your engine's reliability. Our coil ignition system is precision-engineered to address and resolve the most persistent issues faced by GM owners. Upgrading to the EVIL ENERGY ignition coil provides a permanent fix for:
- No Response on Startup: Tired of extended cranking? The high-voltage output of our ig coil ensures your engine fires instantly. By optimizing the car ignition coil discharge, we eliminate cold-start hesitation in your ignition coil Chevy Silverado setup.
- Unwanted Shaking & 'V8 Stumble': Restore your vehicle's smoothness. This EVIL ENERGY ignition coil effectively eliminates the abnormal engine vibrations and shaking often caused by aging 5.3 ignition coils during AFM/DFM cylinder transitions.
- Engine Fault Lights (P0300-P0308): Clear those persistent 'Check Engine' lights for good. Replacing your factory units with our high-output ig coil kit is the most efficient way to resolve misfire codes and prevent your vehicle coil system from triggering 'Limp Mode.'
- Excess Fuel Consumption: Stop wasting gas due to a weak spark. By delivering 52,000V of power, our Chevy ignition coil upgrade ensures total fuel atomization, allowing you to recover lost MPG and improve the towing efficiency of your ignition coil Chevy Silverado.
- Erratic Power Delivery: Whether you're driving a Corvette or a heavy-duty Suburban, our coil ignition system provides the consistent electrical arc needed to eliminate power surges and hesitation common in worn-out 5.3 ignition coils.

Who Should Upgrade Their Vehicle Coil System to EVIL ENERGY?
- Are you experiencing the 'Silverado Shudder' in your 5.3 ignition coils? Late-model ignition coil Chevy Silverado units often struggle with AFM/DFM transitions. Our EVIL ENERGY ignition coil provides the voltage stability needed to eliminate low-end stumbles and P0300 codes in your 5.3 ignition coils, restoring that factory-smooth car ignition coil feel.
- Do you demand track-ready performance from your Chevy ignition coil? Standard vehicle coil packs can falter under the extreme cylinder pressures of a Z06 Corvette or Camaro. Our high-output ig coil ensures your engine receives a consistent, high-intensity arc at redline, maximizing the output of your coil ignition system.
- Are you towing heavy loads with a Yukon XL or Silverado? Towing puts immense stress on your Chevy ignition coil. Replacing your aging factory set with our durable EVIL ENERGY ignition coil set is the smartest preventative maintenance to ensure torque consistency and prevent 'Limp Mode' during heavy-duty hauling.
