Description
The Mishimoto MMB-BR27-21 is a combined Borne Off-Road snorkel and Mishimoto performance cold air intake built specifically for the 2021+ Ford Bronco 2.7L EcoBoost. This isn’t a single generic air intake filter bolted to a stock tube—it’s a two-part air intake system that relocates the fresh air inlet to roof height while replacing the restrictive factory airbox with a high-flow design, giving your Bronco’s EcoBoost engine cleaner, cooler air whether you’re crawling rocks or cruising the highway.
A well-designed cold air intake exists to feed an engine as much cool, clean air as possible, and that job gets harder when a turbocharged engine like the Bronco’s 2.7L EcoBoost is pulling in dusty trail air or splashing through mud. The Borne Off-Road snorkel tube is rotationally molded from durable, UV-resistant cross-linked polyethylene and moves the inlet up to the roofline, topped with a 6-inch inlet and steel mesh cover that can be swapped for a pre-filter. Paired with it, the Mishimoto intake uses a 4.5-in high-flow filter and rotomolded construction to cut restriction by 39.6% versus the stock intake system, translating into dyno-proven gains of 7.5 HP and 7.4 lb.-ft of torque on a stock tune while maintaining a safe air/fuel ratio.

Frequently Asked Questions
What vehicles does the Mishimoto MMB-BR27-21 snorkel and intake kit fit?
It fits the 2021+ Ford Bronco 2.7L EcoBoost, including the Badlands and Outer Banks (2021–2026), Big Bend, Black Diamond, and Wildtrak (2021–2024), Base (2021–2023), First Edition (2021), Heritage Limited Edition (2023–2024), Heritage Edition (2024–2026), and Stroppe Edition (2025–2026).
How much power does this cold air intake system add?
The Mishimoto intake, combined with the Borne Off-Road snorkel, produces dyno-proven gains of 7.5 HP and 7.4 lb.-ft of torque on a stock tune, thanks to the intake being 39.6% less restrictive than the stock intake.
What is the snorkel tube made from?
The Borne Off-Road snorkel tube is precision rotational-molded from durable, UV-resistant cross-linked polyethylene designed to withstand heat and trail debris.
Does the snorkel increase the Bronco’s water fording capability?
No. This snorkel alone does not increase the vehicle’s water fording limit; fording water above the stock recommended limit may require modifying other components to avoid water damage.
What filter material does the Mishimoto intake use?
It uses a multi-layered cotton, oiled, red 4.5-in high-flow air filter as part of the intake system.
What is included with the MMB-BR27-21 kit?
The kit includes the Borne Off-Road snorkel tube, fender tube, snorkel inlet, snorkel-to-airbox adapter and gasket, mounting brackets, stock airbox plug, worm gear clamps, fender modification template, Mishimoto intake airbox, intake tubes, air intake tube grommet, air filter, airbox lid, silicone intake couplers, mounting hardware, and is backed by the Mishimoto Lifetime Warranty.
