Description
The Mishimoto MMAI-BR27-21DW is a performance cold air intake engineered specifically for the 2021+ Ford Bronco equipped with the 2.7L EcoBoost V6. Built from rotational-molded cross-linked polyethylene (XLPE) and paired with a 4.5-inch high-flow air filter, this air intake system delivered dyno-proven gains of 7.5 horsepower and 7.4 lb.-ft. of torque on a stock tune while cutting intake restriction by roughly 39.6% compared to the factory setup.
Every good cold air intake has to balance airflow, heat control, and durability, and that’s exactly what this Mishimoto air intake filter system was designed to do. The XLPE construction keeps engine bay heat out of the intake air while the 20% larger cross-sectional area versus the stock intake tube helps the 2.7L EcoBoost breathe easier. The intake retains the stock fresh air inlet and its dust trap, so off-road dust and debris stay away from the air filter even when the trail gets rough. It’s available with an oiled or dry washable filter to suit your driving environment, and the removable clear airbox lid makes filter inspection simple. For a more complete free-flowing charge air system, this intake pairs with Mishimoto Performance Intercooler Pipes, and drivers can expect a more aggressive intake tone while the system maintains a safe air/fuel ratio on the stock tune. The design is covered under Patent US No. D1,048,102 S and backed by the Mishimoto Lifetime Warranty.
