WR7LTC Spark Plug - Brazilian Bay

The Bosch WR7LTC (or Topran equivalent) is a high-quality short-reach spark plug specifically designed for VW Type 2 Brazilian Baywindow Vans equipped with 1600cc air-cooled fuel-injected engines. This plug combines Bosch’s proven ignition technology with modern interference suppression and efficient heat control, ensuring smooth and reliable performance in classic air-cooled engines with electronic fuel injection.

Featuring an interference suppression resistor (R), the WR7LTC helps prevent electrical noise in sensitive electronic systems — a vital feature for late Brazilian Type 2 models equipped with fuel injection and modern ignition modules. The medium heat range (7) rating offers excellent combustion performance across all operating conditions, while the copper-core electrode provides outstanding conductivity and heat dissipation.

Its short-reach (12.7 mm) design ensures a perfect fit in 1600cc air-cooled heads, preventing thread exposure and maintaining safe piston clearance. The WR7LTC’s robust nickel-plated shell provides corrosion resistance, long service life, and consistent spark performance — ideal for dependable operation in classic VW buses.
