Ignition Coil and Iridium Spark Plugs for Volvo V70 (1998-2004) 2.3L 2.4L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 1998-2004 Volvo V70

What it Does: Replaces worn factory ignition components with direct-fit coil-on-plug packs and fine-wire iridium plugs to restore precise combustion timing, eliminate misfires, and stabilize idle across all 5 cylinders.

The Stock V70 Ignition Breakdown

The Volvo Modular "White Block" inline-5 engine subjects top-mounted ignition coils to extreme thermal cycling within the cramped cylinder head valley. Over time, OEM coil epoxy potting degrades, developing micro-fractures in the housing that leak secondary voltage to ground. Combined with widened spark plug gaps from extended service intervals, this breakdown causes high-load hesitation, rough idle, loss of boost efficiency on turbo models, and persistent P0300–P0305 cylinder misfire codes.

The Engineering Solution

This full service kit features five upgraded coil-on-plug assemblies engineered with high-conductivity oxygen-free copper internal windings and durable silicone boots to resist dielectric breakdown and thermal fatigue. Matched with five pre-gapped iridium-tipped spark plugs, the assembly delivers a concentrated spark kernel, superior anti-fouling capabilities, and steady flame propagation under high cylinder pressures.
