NGK BR5ES Standard Spark Plug for Volkswagen Transporter, Campmobile, and Vanagon (1972–1983)

The NGK BR5ES is a standard spark plug for the Volkswagen Transporter, Campmobile, and early Vanagon, and it replaces a worn plug in the van's engine. NGK sells it as part number 5866 and also references it as 6410. It cross-references to Volkswagen part ZPP121116C, so it matches the factory plug specification for these vans. NGK builds this plug in Japan and rates it as OEM quality. That lines up with how NGK's parent company, Niterra, sells its parts, supplying vehicle manufacturers as factory equipment and selling the same products to the aftermarket.

This NGK spark plug carries a 24-month or 24,000-mile warranty.

A spark plug takes the high-voltage pulse from the ignition system and fires it across the electrode gap to light the air and fuel charge in the cylinder. Plugs wear with every ignition cycle. Common signs that a plug change is due are misfiring, hesitation, loss of power, and poor fuel economy. NGK advises changing plugs at the vehicle maker's service interval and checking their condition for warning signs between changes. The BR5ES is a standard plug, as opposed to the iridium plugs NGK makes for later engines, which suits the ignition systems in these vans.
