The Airtec Motorsport Induction Kit for the Opel Astra J CDTi has been developed to improve the original air intake without losing the factory air supply. By using the original airbox base in combination with an enlarged, two-piece laser-cut cover, space is created for a large 80 mm performance air filter with significantly higher airflow.
The result is improved throttle response, a sportier intake sound, and a more attractive appearance of the engine bay. The kit is fully bolt-on and requires no drilling or modifications.
