Description
The Mishimoto MMBK-BR-21HK is a purpose-built silicone boot kit engineered to bridge the gap between the Mishimoto 2021+ Ford Bronco high-mount performance intercooler and either the 2.3L or 2.7L Mishimoto intercooler pipe kit. Built specifically for owners who purchased their high-mount intercooler and intercooler pipe kit separately, this adapter set restores a factory-tight, leak-free connection through the charge air system.
Each boot in this kit is molded from high-grade silicone using Mishimoto’s DuraCore technology, giving the material improved resistance to oil and fuel exposure while standing up to the demands of a boosted charge air system. Because the pipes and intercooler must mate cleanly for uninterrupted airflow, this stock-location adapter kit is designed as a Specific-fit, Performance-grade solution rather than a universal coupler, ensuring the boots seat properly at the exact factory mounting points on the Bronco’s turbocharged engine bay.
Vehicle Applications
This boot kit is engineered for the Ford Bronco chassis code U725 equipped with the 2.3L Turbo I4 (2.3L EcoBoost) or 2.7L Turbo V6 (2.7L EcoBoost) engine, model years 2021 and up. Coverage spans the Bronco Base (2021–2023), First Edition (2021), Big Bend and Outer Banks (2021–2026), Black Diamond (2021–2024), Wildtrak (2021–2024), Badlands (2021–2026), Everglades (2022–2024), Heritage Edition (2023–2026), and Heritage Limited Edition (2023–2024). It is intended to be used alongside Mishimoto’s high-mount performance intercooler along with either the 2.3L or 2.7L Mishimoto intercooler pipe kit for a complete, matched charge air system.
