Genuine BMW MINI M45 John Cooper Works JCW Supercharger
This little green gasket seals between the supercharger inlet and the black plastic intake pipe attached to the throttle body. If the intake pipe is ever removed we strongly advise you replace it for a new one. A leaking gasket here can create many annoying and dramatic symptoms particularly on initial start-up. Replace this gasket and retain maximum efficacy of your engine and restore its road manners.
