Ignition Coil + Iridium Spark Plugs for Chrysler Intrepid (1998-2004) 2.7L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 1998-2004 Chrysler Intrepid

What it Does: The ignition coil and iridium spark plug kit replaces aged factory coil packs and degraded plugs on the 1998-2004 Chrysler Intrepid to restore spark energy, eliminate cylinder misfires, and stabilize idle quality.

The Stock Chrysler Intrepid Secondary Ignition Breakdown

The Chrysler 2.7L EER V6 utilizes a deep-well coil-on-plug setup that operates under extreme cylinder head thermal stress. Over thermal cycles, the factory epoxy encapsulation in the original UF199 coils micro-fractures, while the silicone boots degrade and succumb to dielectric breakdown. This degradation leads to high-voltage arcing directly to the spark plug tube walls, resulting in secondary winding short circuits, hesitations under load, and DTC codes P0300 through P0306. Simultaneously, standard copper or platinum core plugs suffer rapid gap erosion, placing excessive dielectric load back onto deteriorating coil windings.

The Engineering Solution

This complete ignition service kit pairs six high-dielectric replacement coil packs with fine-wire iridium spark plugs to solve primary and secondary ignition faults. The coils feature reinforced thermal-resistant thermoplastic housings filled with high-vacuum injected epoxy to eliminate air voids and internal arc-over. Heavy-duty silicone boots provide superior resistance to oil vapor and heat hardening. The included spark plugs feature fine-wire iridium center electrodes and laser-welded platinum ground pads, demanding lower firing voltage from the secondary circuit while maintaining precise gap tolerances under sustained combustion chamber temperatures.

Frequently Asked Questions

Does this fit the LH Intrepid?
Yes, this is a direct fit for the 1998-2004 Chrysler Intrepid equipped with the 2.7L EER engine.

Do the iridium spark plugs require gapping prior to installation?
The iridium plugs come pre-gapped, but gap verification with a non-contact wire gauge is recommended to avoid damaging the fine-wire center electrode.
