Direct Ignition Coils (spark coils) help convert low voltage into high energy for your spark plugs to ignite fuel in your engine. A faulty or failed coil can cause a check engine light (trouble code), rough engine idle, poor fuel economy, and engine stalling, just to name a few. Mando direct ignition coils are well-known for being the exact OE replacements for both Hyundai & Kia. Let Mando ensure your engine is running optimal and smooth once again – We Are OE!
