More Spark Energy for a More Complete Burn
The aFe SCORCHER ignition coil 77-92015-MB is an upgraded direct-fit replacement for the factory ignition coil on the 2015-2019 Hyundai Sonata, delivering higher primary voltage and a hotter, longer-duration spark for more complete combustion. A stronger spark translates into improved throttle response, more consistent power delivery across the RPM range, and measurably better cold-start performance. The 77-92015-MB connects to the factory wiring harness using the OEM connector with no modification, making this one of the easiest performance upgrades available for your ignition system.
Key Features
- Higher output voltage versus OEM coil for a hotter, more complete spark
- Direct OEM connector fit, no wiring modification required
- Improved cold-start performance and idle quality
- More complete fuel combustion for improved power and efficiency
- Durable coil windings engineered for extended service life
- Compatible with stock and performance spark plugs
- Backed by aFe Power limited manufacturer warranty

Frequently Asked Questions
Should I replace all coils at once or just the one that failed?If one coil has failed and the others are original, replacing all coils at the same time is recommended. Coils age together and the others are statistically close to failure. Replacing them all during a single service is more cost-effective than multiple labor visits.
Does this coil work with my existing spark plugs?Yes. The 77-92015-MB is compatible with OEM-spec and most popular aftermarket performance spark plugs. If you are running a wider plug gap for performance tuning, confirm the coil's output voltage is sufficient for that gap with your tuner.
Will this coil resolve a P0300 misfire code?If the misfire is confirmed to be coil-related, replacing the suspect coil with the 77-92015-MB should resolve the fault. If misfires persist after coil replacement, test the spark plug, plug wire (if applicable), and injector for the affected cylinder before drawing further conclusions.
How long do these coils typically last?With normal service, aFe SCORCHER coils are designed for extended service life significantly beyond the OEM replacement interval. Exact longevity depends on operating conditions, plug gap, and maintenance history. Inspect coils when servicing spark plugs.
Is this a direct plug-in replacement or does it need an adapter?This is a direct plug-in replacement using the factory wiring harness connector. No adapter, splice, or modification is required. Verify the part number against your vehicle's coil connector type using the fitment data above.
Can I use this coil with a standalone ECU or aftermarket ignition system?In most cases, yes, but confirm coil primary resistance and dwell requirements are compatible with your aftermarket ECU's ignition driver outputs. Consult your ECU manufacturer for coil specification requirements.
Does this require any ECU programming after installation?No. The 77-92015-MB is a direct plug-and-play replacement that does not require ECU reflashing or parameter changes. Clear any existing misfire fault codes after installation and monitor for any recurrence during the first drive cycle.
What is the warranty on this ignition coil?aFe Power provides a limited manufacturer warranty on the 77-92015-MB covering defects in materials and workmanship. Contact aFe Power or us for current warranty terms.
Installation Overview
- Allow the engine to cool and disconnect the negative battery terminal before beginning
- Locate the ignition coil(s) for the cylinder(s) being serviced
- Disconnect the electrical connector from the OEM coil by pressing the tab and pulling straight out
- Remove the coil retaining bolt and pull the coil straight up off the spark plug
- Insert the new aFe 77-92015-MB coil onto the plug and seat it firmly
- Install and torque the retaining bolt to factory specification
- Connect the electrical harness connector until it clicks into place
- Reconnect the battery, start the engine, and check for any stored misfire codes
