Bosch 8182 Spark Plug

Bosch OE Fine Wire Double Platinum Spark Plug

Bosch 8182 is an OE Fine Wire Double Platinum spark plug built for steady ignition performance and extended service life. It uses platinum on the center electrode and a platinum inlay on the ground electrode to reduce gap erosion and maintain consistent firing characteristics over time.

Compatible With select Volkswagen Golf, Jetta, Beetle, Passat, EuroVan, Golf City, Jetta City, Phaeton, and Audi A8 Quattro applications, this plug is a direct-fit choice for vehicles that call for a preset-gap double platinum design. Bosch 8182 is a practical OE-style replacement for drivers servicing ignition systems on VW and Audi platforms.

• Double platinum construction for improved durability and longer electrode life
• Platinum firing pin on the center electrode
• Platinum inlay on the ground electrode to help reduce gap erosion
• Preset gap; do not gap before installation
• Resistor spark plug with 6000 resistance
• Projected ceramic insulator design
• Flat seat, 14 mm thread diameter, 19 mm reach, 16 mm hex
• OE Fine Wire Double Platinum line for factory-style ignition performance

Detailed Description

Bosch 8182 is part of the OE Fine Wire Double Platinum product line, which focuses on OE-level spark plug construction for modern ignition systems. The fine-wire platinum center electrode and platinum ground electrode insert are used to control wear at the firing surfaces, helping the plug maintain its preset gap and stable spark delivery under normal service conditions. This design is well suited for Volkswagen Golf and Jetta models, as well as Beetle, Passat, EuroVan, Phaeton, Golf City, Jetta City, and Audi A8 Quattro applications listed in the fitment data.

This part number, 8182, is a direct replacement option for vehicles that specify a double platinum, flat-seat spark plug with a preset gap. It is built with a ceramic insulator, nickel-y yttrium and copper core materials, and a projected insulator type to match OE-style secondary ignition requirements.

Common Issues This Plug Can Address

• Worn spark plug electrodes from normal ignition system use
• Misfire concerns related to aged or eroded plugs
• Hard starting caused by degraded spark delivery
• Rough idle from inconsistent combustion at the plug
• Reduced service life from standard copper plug wear
