Vortech Maxflow Race Blow-Off Valve Upgrade - Black (2021-2026 F-150 5.0L) 4FV212-104
Black Maxflow Race Blow-Off Valve Upgrade for Supercharged F-150 5.0L
The Vortech Superchargers Maxflow Race Blow-Off Valve Upgrade (PN 4FV212-104) is engineered for 2021-2026 Ford F-150 5.0L supercharged applications that demand rapid pressure relief and the unmistakable vent-to-atmosphere race sound between shifts. This black-finish upgrade replaces the factory charge tube with a dedicated tube featuring a pre-welded flange designed specifically to mount the included Maxflow Race BOV.
Ideal for high-performance street and race setups, the Maxflow Race BOV delivers crisp boost discharge under throttle lift, helping reduce compressor stress while producing a sharp, aggressive blow-off sound that enthusiasts expect from a true race-style system.
Maxflow Race BOV Design & Function
The Maxflow Race Blow-Off Valve is CNC-machined from billet aluminum and uses a large rolling diaphragm with dual vent porting for fast, consistent valve response. The valve features a 360-degree discharge design and is preset by Vortech to open at 5-7 inches of vacuum, making it well suited for high-boost, vent-to-atmosphere (VTA) supercharged systems.
This BOV shares the same mounting flange configuration as the Vortech Race Bypass Valve, including the 1.51" / 38.51mm inlet, allowing for straightforward replacement on compatible Vortech VTA applications.
