MANN-FILTER WK 830/7 Fuel Filter (1H0201511) | VW Golf, Jetta, Passat & Audi

MANN-FILTER WK 830/7 Fuel Filter (In-Line, Metal Housing)

Hesitation or surging under load, hard starts, power fading at high RPM, a whining fuel pump — these are classic signs of a clogged fuel filter starving the injection system.

The MANN-FILTER WK 830/7 is the OE-quality in-line fuel filter for a whole generation of water-cooled VW and Audi gasoline injection engines. Metal housing, ~10 micron cellulose media, 8 mm hose connections — the same specification the factory called for.
