Aeroflow Performance air pump delete plates are the perfect solution to removing the troublesome factory air pump system on your Subaru EJ25 engine. They are machined from billet aluminium and anodized black finish for a durable long-lasting protection. These block off covers come complete with two covers one for each cylinder head to cover the ports when the air pump tubes are removed. New stainless-steel hardware is included, and the factory OE gaskets must be reused to seal them. Note: Tuning is required after installation to resolve codes caused by removing air pump system.
