GREEN FILTER direct induction kit for OPEL Astra or Calibra 16V

Optimise the performance of your OPEL Astra or Calibra with the GREEN FILTER direct induction kit. By increasing the amount of air entering the cylinders, the engine becomes more efficient. The original airbox and filter systems can restrict this airflow. Replacing them with a direct induction kit significantly improves airflow by reducing resistance. This kit removes the original airbox and often shortens the distance between the air inlet and the engine, resulting in a notable power gain at low engine speeds, as well as improved torque and in-gear acceleration. For optimal performance, it is recommended to isolate the induction kit within the engine bay to prevent hot air from being drawn in.

This kit is compatible with:

• OPEL Astra 2.0 GSi 16V (150CV) from September 1991 to February 1998
• OPEL Calibra 2.0 16V (150CV) from 1990 to 1994
