Installing
Install in the reverse order from removal, remembering the following:
  Note
t  Apply the correct tightening torques.
t  Renew seals, gaskets and self-locking nuts.
t  Note the installation position of intake manifold gasket.
t  The sleeves for the hoses and the supercharger air flow tubes should be free of oil and grease before fitting.
t  Secure all hose connections with the correct hose clips (same as original equipment) → Parts catalogue.
