Phat Bars BT-50 Airbox, 4JJ3 (2021 On)
Bolt-in performance airbox for the Mazda BT-50 3.0L 4JJ3, built for Aussie conditions
Factory fit, trail-proven performance. The Phat Bars BT-50 airbox is a direct bolt-in replacement that uses the factory mounts and grommets, keeping a tidy OE-like finish while improving induction efficiency and reliability. Powder-coated alloy construction, a one-way drain valve, and an off-road pre-filter sock make it water and dust resistant for harsh Australian conditions.
