Ignition Coil and Iridium Spark Plugs for Kia Amanti (2004-2006) 3.5L

Direct-Fit Ignition Coil and Iridium Spark Plug Service Kit for 2004-2006 Kia Amanti

What it Does: The ignition coil and iridium spark plug kit replaces worn factory waste-spark secondary components on the 2004-2006 Kia Amanti to resolve engine misfires, restore lost combustion efficiency, and stabilize idle quality.

The Stock Kia Amanti Ignition Breakdown

The transverse-mounted 3.5L V6 in the GH chassis utilizes a waste-spark setup where thermal loading concentrates heavily on the rear cylinder bank under the intake plenum. Over time, engine bay heat cycles degrade factory coil potting resin and dielectric insulation boots, causing high-voltage leakage, carbon tracking, and intermittent secondary circuit breakdown. Paired with aged copper or standard platinum plugs whose electrode gaps erode over time, the increased secondary resistance overburdens the driver circuits, triggering P0300-P0306 diagnostic trouble codes, hesitation under load, and reduced fuel economy.

The Engineering Solution

This comprehensive tune-up kit features three heavy-duty ignition coils engineered with high-grade copper windings and vacuum-poured epoxy encapsulation to resist internal arcing and thermal breakdown. Matched with six fine-wire iridium spark plugs, the package delivers a concentrated spark discharge requiring lower firing voltage. The iridium core provides superior erosion resistance under high chamber temperatures, maintaining precise electrode gaps across extended intervals while ensuring complete flame front propagation in the Sigma G6CU combustion chamber.

Frequently Asked Questions

Does this fit the GH Amanti?
Yes, this is a direct fit for the 2004-2006 Kia Amanti equipped with the 3.5L Sigma G6CU engine.

Why are there only three coils included for a six-cylinder engine?
The 3.5L V6 utilizes a waste-spark ignition configuration where three dual-tower coils each fire one direct cylinder and one companion cylinder via high-tension plug leads.
