Ford F‑Truck Airbox Replacement

Ford F‑Truck Airbox Replacement

To Suit Ford F‑250 / F‑350 / F‑450 / F‑550

Upgrade your Ford F‑Series Super Duty with the EC Offroad Airbox Replacement — a purpose‑built solution designed to improve airflow positioning and enhance engine protection during water crossings, heavy rain, and off‑road conditions. Engineered in Australia for harsh environments, this upgraded airbox replaces the factory lower intake section and relocates the air entry point to a higher, safer position.

This system delivers the key benefits of a raised intake without the need for a snorkel, offering improved water‑crossing capability while maintaining a clean, factory‑style appearance. It also avoids the common wind noise and resonance associated with external snorkels, giving you a quieter, more refined driving experience.
