Ignition Coil and Iridium Spark Plugs for Lincoln MKS (2010-2012) 3.5L

Direct-Replacement Ignition Coil and Iridium Spark Plug Kit for 2010-2012 Lincoln MKS

What it Does: The ignition coil and iridium spark plug kit replaces aged factory ignition components on the 2010-2012 Lincoln MKS 3.5L to eliminate high-boost misfires, restore clean combustion, and stabilize idle quality.

The Stock Lincoln MKS Secondary Ignition Breakdown

Factory pencil coils on the D385 chassis endure extreme heat cycling nestled deep inside the cylinder head wells of the twin-turbocharged 3.5L EcoBoost V6. Over time, heat exposure degrades the internal epoxy potting, leading to dielectric breakdown and secondary voltage leakage. Paired with spark plug electrode gap widening under forced induction, cylinder pressure blows out the ignition spark, producing hesitation under boost, rough idle, and intermittent P0300 through P0306 diagnostic trouble codes.

The Engineering Solution

This comprehensive service pack pairs high-output direct-fit ignition coils with fine-wire iridium spark plugs designed specifically for forced-induction thermal environments. The replacement pencil coils utilize premium copper windings and high-temperature silicone boots to stop dielectric flashover and voltage tracking. The iridium plugs feature an ultra-dense, laser-welded fine-wire center electrode that lowers required firing voltage, resisting quench and spark blowout across the broad torque band of the twin-turbo V6.

Frequently Asked Questions

Does this fit the D385 MKS?
Yes, this is a direct fit for the 2010-2012 Lincoln MKS equipped with the 3.5L EcoBoost engine.

Do these spark plugs require gapping prior to installation?
Plugs arrive pre-gapped, but verifying the factory 0.030–0.033 inch gap prior to installation ensures optimal flame kernel propagation under boost.

The Lincoln Touring Caliber

Lincoln luxury platforms require uninterrupted power delivery to maintain smooth cabin refinement; installing a matched coil and plug set preserves rapid throttle tip-in and prevents power loss under load without throwing check engine lights.
