The Racingline Performance Washer bottle Cap is beautifully over-engineered in customary Racingline Performance fashion to give an exquisite feel and exceptional product experience. The Racingline Performance Washer Filler Cap provides a complete replacement for the plastic OEM version with a good quality look and feel.
Fitting is pretty obvious – just remove the existing cap, and slip this one in place!
