Astra GSI SRI Airbox Crossover Kit MK4 70MM CDTI Black

MTC Motorsport Crossover Delete for an Astra GSI SRI Z20LET for 70mm airflow meter

• More direct airflow straight into the turbocharger by removing the standard crossover pipe which is prone to heat soak from the engine.
• Higher volume of cooler air as it has a larger internal diameter than the aluminium crossover that comes as standard.
• Handmade with 5 layers of silicone
• Fluoro-lined to prevent discolouration
• Fits to either a cone filter or CDTI airbox.

They fit on to the 70mm AFM of the Z20LET Z20LER and also Z20LEL. For VXR Crossover Delete hoses, please see our other items as these have an 80mm MAF.

Included in the kit:

• Silicone Crossover Delete
• Cam Cover Breather Hose
• CNC Alloy Connector
