Will this O-Ring fit my 1986–1991 Volkswagen Vanagon with Digifant fuel injection?

Yes! This square O-Ring is specifically designed to fit between the air filter housing and the air flow meter on all 1986–1991 Volkswagen Vanagon models equipped with the Waterboxer engine and Digifant fuel injection. If you have a Vanagon from those years with the Digifant system, you can count on a perfect fit—just like our customers say.

How do I know if my air flow meter O-Ring needs to be replaced?

Common signs that your O-Ring needs replacing include a loose fit between the air filter housing and the air flow meter, visible cracks or wear on the original O-Ring, or unmetered air leaks affecting engine performance. Replacing a worn O-Ring can help restore a proper seal and smooth out idling or hesitation issues. This O-Ring is a direct Volkswagen (part number 025-129-683) replacement, ensuring OE quality and excellent sealing.

Is installing this O-Ring for the air flow meter a straightforward DIY job?

Absolutely! To install this O-Ring, simply remove the air filter housing, slide off the old O-Ring, and fit the new one in place between the air filter housing and the air flow meter. It's a quick job that typically requires just basic hand tools—no special equipment needed. For best results, check that the surfaces are clean before installing the new O-Ring, and enjoy restored performance and peace of mind!
