BOSCH Cis Fuel Injection system sealing washer kit. When doing any maintenance on your fuel system, be it something basic like changing a fuel filter or more in depth like replacing a fuel distributor. Each copper sealing washer you encounter along the way should be replaced as they deform under pressure once cranked down the first time and will require excessive torque to reseal properly or improperly I should say.
Fits: All Vw/Audi/Porsche Bosch CIS fuel injection Systems
Each kit includes: (enough to rebuild one system on just about all applications)

20 Small (eg. Fuel distributor,Injection Line, Csv, Wur, etc.)
