High-Output for Ford F150 & Explorer

Need to replace OE UF646? EVIL ENERGY ignition coils are engineered for performance, offering stronger spark, faster response, and rock‑solid stability. Direct replacement upgrades your engine without costly modifications.

Restore the relentless twin-turbo power of your engine with the EVIL ENERGY ignition coil series. Specifically engineered as a high-performance replacement for the OE UF646, this 3.5 ecoboost ignition coil solution is the definitive fix for Ford's V6 platforms. Whether you are searching for a reliable ignition coil Ford F150 owners trust or a durable Ford Explorer ignition coil, our kit delivers a massive 43,000V maximum voltage to ensure your spark remains stable even under maximum boost pressure.

Built to optimize combustion efficiency and upgrade your driving experience, EVIL ENERGY ignition coils deliver reliable performance, enhanced stability, and long-term durability.

Why EVIL ENERGY is the EcoBoost Standard:

  • Unmatched Spark Energy: Featuring +17% spark energy over stock, this F150 ignition coil kit provides the precise 1.58 mS spark duration required for complex twin-turbo combustion cycles.
  • Boost-Ready Engineering: The 3.5 ecoboost ignition coil environment is notoriously harsh; our coils utilize an 84:1 turns ratio and 0.63 ohms primary resistance to resist heat soak and prevent high-RPM misfires.
  • Rock-Solid Stability: Every EVIL ENERGY ignition coil is built to outperform standard Ford Explorer ignition coil replacements, offering the faster response and cleaner combustion needed for today's high-output Ecoboost engines.

Feature:

  • Boost Power & Fast Ignition: Specifically optimized for the high-pressure 3.5 ecoboost ignition coil platform, our units ensure rapid ignition and efficient combustion. By upgrading to an EVIL ENERGY ignition coil, you can effectively increase horsepower, sharpen throttle response, and maximize the overall output of your ignition coil Ford F150.
  • Reduce Jitter & Rough Idle: Say goodbye to the annoying 'EcoBoost shudder.' Replacing worn factory components with this premium F150 ignition coil helps eliminate engine vibration and irregular idle. It provides the smoother acceleration and steady operation expected from a high-quality Ford Explorer ignition coil.
  • Reduce Fuel Consumption: Maximize your miles per gallon by enhancing combustion efficiency. Our EVIL ENERGY ignition coil technology ensures more complete fuel burning, reducing excess fuel usage and supporting better fuel economy—an essential upgrade for any heavy-duty ignition coil Ford F150 application.
  • High-Temperature Resistant: Ford’s twin-turbo engine bays generate extreme heat that can degrade standard F150 ignition coil units. Our coils are made from advanced, durable heat-resistant materials to withstand these harsh conditions, ensuring your 3.5 ecoboost ignition coil maintains peak performance without thermal failure.
  • Stable & Durable Engineering: Designed with robust construction and lasting reliability, this EVIL ENERGY ignition coil set is built to endure. Whether you need a consistent Ford Explorer ignition coil for daily commuting or a heavy-duty F150 ignition coil for towing, our design ensures dependable ignition performance over time.

Is the EVIL ENERGY Ignition Coil Right for Your Ford?

  • The Daily Commuter: If your Ford Explorer ignition coil is failing, you’ll feel a 'shudder' during highway merging. Our EVIL ENERGY ignition coil restores factory-smooth acceleration and eliminates that annoying 'EcoBoost stumble.'
  • The Towing & Hauling Professional: Towing with a weak ignition coil Ford F150 leads to dangerous power loss. Our high-voltage F150 ignition coil ensures your V6 has the torque consistency needed for heavy trailers and steep grades.
  • The High-Mileage Maintainer: Prevent the 'Limp Mode' surprise. Replacing your old 3.5 ecoboost ignition coil set at 60k miles with EVIL ENERGY is the smartest preventative maintenance for any 3.5L Ford or Lincoln vehicle.

Restore Smooth & Reliable Driving with EVIL ENERGY

Don't let a failing 3.5 Ecoboost ignition coil compromise your vehicle's safety. Our high-performance ignition coil kit is precision-engineered to be the definitive fix for Ford’s most persistent V8 and V6 engine frustrations. Upgrading to the EVIL ENERGY ignition coil effectively targets and resolves:

  • Hard Starting & Cold Start Hesitation: Eliminate extended cranking and weak turn-overs. The EVIL ENERGY ignition coil provides a rapid, high-voltage spark that ensures your F150 ignition coil system fires instantly, even in freezing temperatures.
  • Abnormal Shaking & 'EcoBoost Shudder': Restore your engine's balance. This ignition coil Ford F150 owners recommend is designed to eliminate the low-end vibration and cabin shaking caused by weak Ford Explorer ignition coil performance under load.
  • Persistent Engine Fault Alerts (P0300-P0306): Permanently clear "Check Engine" lights and misfire codes. Replacing your aging factory units with our F150 ignition coil kit is the most effective way to extinguish dashboard alerts and prevent the vehicle from entering 'Limp Mode.'
  • Poor Fuel Economy & Power Loss: Stop wasting gas due to incomplete combustion. By delivering a more intense spark, the 3.5 ecoboost ignition coil upgrade ensures total fuel atomization, helping you recover lost MPG and the towing torque you expect from an ignition coil Ford F150.
  • Long-Term Driving Stability: Whether you are daily driving a Transit or pushing a Ford Explorer ignition coil to its limits on a family road trip, our EVIL ENERGY ignition coil ensures a stable and reliable ignition path for thousands of miles.

If you need further information or assistance, feel free to ask!

Q: Can a bad Ford Explorer ignition coil cause a 'shudder' without a CEL?
A: Yes! EcoBoost engines often suffer from 'low-grade misfires' that won't trigger a Check Engine Light but cause a noticeable shudder. Upgrading to an EVIL ENERGY ignition coil can eliminate this 'phantom' vibration.

Q: Is the EVIL ENERGY ignition coil compatible with the 3.5L Non-Turbo engine?
A: Yes, our UF646 ignition coil kit fits both the 3.5L Ti-VCT (Non-Turbo) and the 3.5L EcoBoost V6 used in the Ford Explorer ignition coil applications from 2013-2019.

Q: Does the 3.5 Ecoboost ignition coil require a smaller spark plug gap?
A: High-performance coils like EVIL ENERGY (with 43,000V output) can handle standard gaps, but for tuned engines, we recommend a tighter gap (0.028-inch) paired with our high-voltage F150 ignition coil to prevent blowout.

Q: How often should I replace my F150 ignition coil kit?
A: For EcoBoost owners, we recommend a refresh every 60,000 miles. This prevents the stress on the catalytic converters caused by weak ignition coil Ford F150 units.

Q: Why is my Ford Explorer ignition coil leaking 'electricity' (Arcing)?
A: Heat and moisture break down the rubber boot. EVIL ENERGY ignition coil uses high-dielectric silicone boots to prevent the energy from escaping to the engine block.

Q: Does upgrading to EVIL ENERGY LS-style performance coils improve MPG?
A: By providing a +17% spark energy boost, our 3.5 ecoboost ignition coil ensures more complete combustion, which typically recovers 1-2 MPG lost to aging coils.

Q: Is it hard to replace the ignition coil Ford F150 packs on the 3.5L?
A: The passenger side is easy, but the driver's side requires moving some vacuum lines. It’s a 45-minute DIY job with an EVIL ENERGY ignition coil kit.

Q: Can I replace just one F150 ignition coil?
A: You can, but since these coils share the same heat cycles and age, replacing the full ignition coil kit ensures consistent resistance across all cylinders.

Q: What makes the EVIL ENERGY 3.5 ecoboost ignition coil different from OE?
A: We use an 84:1 turns ratio and high-temp epoxy, allowing our F150 ignition coil to deliver 43,000V—significantly higher than standard factory replacements.

Q: Will these coils solve the 'Limp Mode' issue on my Ford Explorer?
A: If your Limp Mode is caused by P0300-P0306 misfire codes, then a high-quality Ford Explorer ignition coil set from EVIL ENERGY is exactly what you need to restore reliability.
