for an Astra GSI SRI Z20LET for 70mm airflow meter.

This hose kit provides a more direct airflow straight into the turbocharger by removing the standard crossover pipe that is prone to heat soak from the engine. This kit delivers a higher volume of cooler air as it has a larger internal diameter than the aluminium crossover that comes as standard.

 You can either fit this kit to a cone filter or a CDTI air box.

Included in the kit:

- Silicone Crossover Delete

- Cam Cover Breather Hose

- CNC Alloy Connector
