Ignition Coil & Spark Plugs for Oldsmobile Cutlass Supreme (1993-1997) 3.1L 3.4L V6

Direct-Fit Ignition Coil & Spark Plugs for 1993-1997 Oldsmobile Cutlass

What it Does: Restores factory ignition performance and eliminates misfires by delivering a consistent, high-voltage spark to the combustion chamber.

The Stock Cutlass Ignition Weakness

Over time, the factory coil packs on the GM 60-degree V6 Distributorless Ignition System degrade due to severe under-hood heat cycling and engine vibration. This relentless heat soak breaks down the OEM internal epoxy potting, leading to micro-cracking in the secondary windings. The resulting voltage leaks cause weak spark delivery, intermittent engine misfires under heavy load, and rough idling. If left unchecked, unburnt fuel enters the exhaust system, which can severely damage the catalytic converter and drastically reduce fuel economy.

The Engineering Solution

This replacement ignition coil and NGK spark plug kit is manufactured to rigorous ISO/TS16949 quality standards to outlast original equipment. The updated ignition coils feature high-temperature resistant epoxy and upgraded internal copper wire windings to prevent electrical breakdown during extreme engine heat soak. Paired with six precise-gap NGK spark plugs utilizing highly conductive center electrodes, this package ensures optimal flame kernel propagation inside the cylinder. The enhanced dielectric properties and corrosion-resistant terminals guarantee a strong, uninterrupted high-voltage transfer from the W-body ignition module directly to the cylinders, restoring crisp throttle response and ensuring a complete combustion cycle.
