Ignition Coil & Iridium Spark Plugs for Volkswagen Touareg (2007-2008) 4.2L V8

Direct-Fit Ignition Coil & Iridium Spark Plugs for 2007-2008 Volkswagen Touareg

This comprehensive ignition overhaul kit replaces aging factory coils and plugs to restore proper combustion, eliminate misfires, and improve fuel efficiency on the 4.2L FSI V8.

The Stock Touareg Ignition Weakness

The 4.2L FSI (BAR) V8 engine in the 7L Touareg is notorious for excessive heat cycling within the cramped engine bay. This thermal stress prematurely degrades the epoxy and internal windings of the OEM ignition coils. As the factory coils age, internal resistance increases, leading to weak spark delivery under heavy load. This typically manifests as rough idling, hesitation during acceleration, flashing check engine lights, and cylinder misfire codes (P0300-P0308). Additionally, standard platinum spark plugs wear down at the electrode over time, increasing the gap and forcing the coils to work harder, rapidly accelerating their failure rate.

The Engineering Solution

This replacement kit tackles voltage drop and thermal degradation head-on. The upgraded ignition coils are wound with high-purity, durable copper wire, minimizing electrical resistance and ensuring consistent voltage output to the plugs, even under high ambient engine temperatures. The coil housing is constructed from high-dielectric polymer to resist thermal cracking and prevent high-voltage arcing. Paired with the coils are eight premium Iridium spark plugs. Iridium's extremely high melting point allows for a much finer center electrode, which concentrates the electrical field to produce a stronger spark while requiring less firing voltage. This translates to an up to 15% increase in combustion energy transfer, yielding smoother power delivery, stabilized idle, and true OE+ durability.
