Ignition Coil + Spark Plugs for Kia Sedona (2015-2017) 3.3L

Direct-Fit Ignition Coil and Spark Plug Tune-Up Kit for 2015-2017 Kia Sedona

What it Does: The complete ignition kit replaces worn coil packs and fouled spark plugs on the 2015-2017 Kia Sedona to eliminate cylinder misfires, stabilize erratic idle, and restore factory combustion efficiency.

The Stock Kia Sedona Secondary Ignition Breakdown

The Lambda II GDI 3.3L V6 in the third-generation YP chassis subjects coil-on-plug (COP) assemblies to extreme thermal cycling beneath the upper intake plenum. Over time, engine bay heat soak degrades the internal epoxy encapsulation and copper primary/secondary windings in the factory coils. Concurrently, dielectric breakdown in the silicone boots allows high-voltage arc-over, while direct-injection soot accelerates electrode erosion on the factory plugs. This results in wide spark gaps, high coil primary resistance, intermittent hesitation under load, poor fuel economy, and P0300 through P0306 diagnostic trouble codes.

The Engineering Solution

This comprehensive tune-up kit restores high-voltage secondary output via 6 precision-wound ignition coils paired with 6 matched high-durability spark plugs. Each ignition coil features high-dielectric epoxy potting, thermal-resistant silicone boots, and premium magnetic core laminations engineered to prevent insulation breakdown under high underhood operating temperatures. Combined with properly gapped, heat-dissipating plugs designed for gasoline direct injection (GDI) cylinder pressures, this kit eliminates spark blowout, ensures clean flame-front propagation, and preserves catalytic converter health.

Frequently Asked Questions

Does this fit the YP Sedona?
Yes, this is a direct fit for the 2015-2017 Kia Sedona equipped with the Lambda II GDI 3.3L engine.

Do I need to pull the upper intake manifold to install the rear coils?
Yes, servicing the rear bank coils and plugs on transverse 3.3L YP models requires unbolting the intake plenum, making full coil and plug replacement together the standard professional procedure.

The Kia Workhorse Reliability

Minivan platforms require sustained low-end torque and uncompromised reliability under passenger and cargo payloads. Installing matched high-output coils and fresh plugs maintains clean ignition cycles and consistent cylinder pressure for dependable, long-haul family transit.
