Roush 422233 R-Series Cold Air Intake for 2021-2024 Ford Bronco 2.3L/2.7L

Vehicle Fitment

• 2021-2024 Ford Bronco - 2.3L EcoBoost (4-cylinder turbo), all trim levels, 2-door and 4-door
• 2021-2024 Ford Bronco - 2.7L EcoBoost (V6 twin turbo), all trim levels, 2-door and 4-door

Fitment Notes

• Fits all 2021-2024 Ford Bronco trim levels (Base, Big Bend, Black Diamond, Outer Banks, Badlands, Wildtrack, Everglades) and chassis configurations (2-door and 4-door) with 2.3L or 2.7L EcoBoost engines - but see exclusions below
• Does NOT fit the Ford Bronco Sport - the Bronco Sport uses a different platform and engine bay layout; this intake is designed for the full-size Bronco only
• Does NOT fit Bronco Everglades or Bronco equipped with the Ford factory snorkel intake - the factory snorkel system uses a completely different intake routing that conflicts with this Roush system
• Uses factory Bronco mounting locations and hardware - no drilling, cutting, or permanent modification to the engine bay required; factory hardware is reused for installation
• 2025 model year fitment: verify with Roush or your retailer before ordering; the confirmed fitment range is 2021-2024

Features

• R-Series design for off-road use - the 422233 is Roush's Bronco-specific air induction system developed with the off-road use case as the primary design driver; unlike urban performance intakes that maximize induction noise and airflow for dyno numbers, the R-Series addresses the specific challenge of Bronco off-road use: dusty trails, water crossings, mud, and prolonged periods in environments where the OEM airbox struggles to maintain filter protection
• 30% more filtration surface area than the OEM filter - by increasing the filter's contact area, the system reduces the rate at which the filter restriction increases as debris accumulates; on trail, where the filter is constantly intercepting dust and particulates, a larger surface area means more miles between cleaning intervals and less engine inlet restriction during a long day of off-road driving
• Maintains factory water fording capability - the airtight intake gasket seal is the key feature that sets the 422233 apart from most aftermarket cold air intakes for the Bronco; the factory Bronco is rated for water crossings up to a specific depth, and the Roush system is specifically engineered to maintain this capability; the intake gasket creates a sealed barrier that prevents water ingestion into the engine during water crossings, protecting the EcoBoost engines from hydrolocking - the primary failure mode of poorly designed aftermarket intakes on water-capable off-road vehicles
• R-Series pre-filter system - a sliding sleeve-style pre-filter that fits over the air intake housing and is designed to intercept water and large debris before they reach the primary air filter; the pre-filter is removable and washable for periodic servicing, prolonging the primary filter's service life and flow capacity; the pre-filter features the Roush "R" logo and is a distinctive visual element of the R-Series system
• See-through monitoring window - a clear window in the intake lid allows visual inspection of the primary filter's condition without removing any components; on trail this allows a quick filter check during a stop without disassembling the intake, making it practical to assess whether the filter needs servicing before continuing to drive in dusty conditions
• Injection-molded plastic construction with OE-appearance texture - the airbox and intake components are manufactured from durable injection-molded plastic with a surface texture that matches the factory underhood panels; the system provides a clean, factory-integrated appearance rather than the aftermarket aesthetic of typical cold air tubes and exposed filter cones
• No oiling required for routine maintenance - the filter does not require periodic re-oiling; cleaning involves washing and allowing to dry; this is particularly practical for off-road use where re-oiling schedules are inconvenient and where oil-contaminated mass airflow sensors are a service issue
• Increased EcoBoost turbo induction sound - the intake system provides a mild increase in the audible turbocharger induction note under acceleration, adding a performance character to the 2.3L and 2.7L EcoBoost sound profiles
• 50-State emissions legal - CARB Executive Order (EO) number D-418-44; fully legal for use on road-registered vehicles in all 50 states including California
• Uses factory mounting locations and hardware - straightforward installation using existing Bronco engine bay mounting points; no new holes, brackets, or permanent modifications
• Roush plaque included - branded placard for under-hood display

Product Description

The Roush 422233 is the R-Series Cold Air Induction System for the 2021-2024 Ford Bronco with 2.3L or 2.7L EcoBoost engines - Roush Performance's Bronco-specific intake designed around the off-road use case rather than street performance metrics alone. Roush developed the R-Series intake from their experience in off-road racing, targeting the specific challenges the Bronco's engine faces in its intended environment: sustained dust exposure, water crossings, trail debris, and the need to maintain factory-rated engine protection while also improving airflow over the restrictive OEM setup.

The intake's two most important off-road-specific features are the airtight intake gasket seal and the R-Series pre-filter. The gasket seal maintains the Bronco's factory water fording depth capability - the critical specification that most aftermarket cold air intakes for the Bronco sacrifice in exchange for better flow numbers; without a properly sealed intake, water crossings risk hydrolocking the EcoBoost engine. The R-Series pre-filter slides over the intake housing as a removable sleeve, intercepting water spray and large debris before they load the primary filter. Combined, these two features allow the 422233 to be used in the same demanding environments the stock intake was designed for, while delivering 30% more filtration surface area and improved airflow.

The see-through monitoring window is a practical trail feature unique to this system - a clear lid section that allows visual assessment of the filter's dust loading without removing the intake components, so a quick check during a trail stop determines whether the filter needs service before continuing. The injection-molded plastic construction matches the factory underhood panel texture for an OE-appearance installation using the Bronco's factory mounting points and hardware. The system is 50-State emissions legal under CARB EO# D-418-44. It does not fit the Bronco Sport, the Bronco Everglades, or any Bronco already equipped with Ford's factory snorkel intake.
