Description

Some airboxes from the factory are capable of providing the necessary airflow for most aftermarket upgrades and filtration requirements, but when upgrading turbochargers as well, some Toyota owners will need to reconsider their airflow efficiency.

Just Autos advises their customers to retain their factory filters when upgrading their airbox. This is because servicing aftermarket filters can be tricky, and not doing a thorough job means a risk to your engine.
