Getting an aftermarket airbox assembly for your 300 Series Land Cruiser can help your engine achieve better airflow over the factory airbox, which is critical when tuning. Toyota factory airboxes are also notorious for poor dust-proofing.

Getting an aftermarket airbox can save you money in the long run as getting dust into your engine can cause irreversible damage to it.
