This hose kit has been designed to cut out the cross over pipe work on the Vauxhall Astra GSI and can be used with a universal 70mm cone filter or a 1.9 CDTI airbox.

The kit contains a direct route induction hose, a 16mm internal diameter Fluoro-lined breather hose, a 16mm stainless steel joiner and fitting instructions.

The 1.9CDTI airbox requires no DIY modification when used with this kit, as the Astra GSI airflow meter (70mm) fits inside the airbox opening and clips in position.

 Please note that if you are planning to use a VXR airflow meter (80mm), you should purchase the VXR direct route kit and follow the same fitting guidelines as the VXR too.

All silicone hoses from JS Performance are manufactured to the highest of specifications using the best quality materials and workmanship to ensure we meet and exceed OEM specifications.
