Description
This original equipment manufacturer (OEM) spark plug is engineered to deliver highly precise ignition for Volkswagen Group’s advanced TSI and TFSI turbocharged gasoline engines across a broad range of models, including the Jetta, Passat, Polo, Audi A1, and Audi A3. Despite the frequent presence of “copper” core descriptors in online retail headers, this component is strictly a premium platinum spark plug that features a fine-wire platinum center electrode welded to a highly wear-resistant earthed tip. This dual-precious-metal configuration protects against extreme combustion temperatures and electrical erosion under intense boost conditions, stabilizing the engine’s idle, preventing fuel-wasting misfires, and guaranteeing a long operational life cycle of up to 55,000 to 60,000 miles (90,000 km)
