RacingLine Turbo Inlet Hose – SEAT Leon Cupra

A simple fitment, it replaces the entire restrictive rear factory plastic bellows pipe between the airbox and the turbocharger inlet.

The large diameter smooth-flowing silicon hose, crucially with enough compliance to allow for adequate engine movement without causing damage to the intake.

Back-to-back comparisons with the factory pipe on our flow bench reveals an impressive improvement in airflow, and makes this hose a great compliment to the R600 intake.

Put simply, you’ll be wasting a chunk of the hard-gotten gains from your high-flow intake system if you leave this pipe standard.
