Mountune Uprated Air Recirculation Valve Focus ST - 2226-TRV-AA

Forced induction components mainly consist of supercharger or turbocharger parts that are used to make significant power gains on your vehicle. If you are looking for a significant increase in horsepower, look no further than forced induction.

Blow off valves are designed to relieve the boost pressure from your intercooler piping when you let your foot off the gas. Doing so, the blow off valve protects your turbo from early wear and tear. Aftermarket blow off valves allow for proper pressure relief and often make cool sounds.

Mountune was founded in Maldon, Essex UK in 1980 by David Mountain.

Originally focused on developing the British Leyland A series engine for motorsport use, the company expanded quickly backed by the reputation gained from numerous race victories. Ford released the infamous 2.0L YB engine powering the Sierra RS in 1986. David Mountain quickly realized the potential of this twin cam, four valve turbocharged engine and started development for race and rally applications. Mountune's team of engineers worked closely with Ford's own motorsport group based at the infamous Boreham facility in the UK to supply various works teams and 100s of privateers with Ford YB engines. In 1990, the Mountune powered Ford Sierra RS500 of Rob Gravitt won the British Touring Car Championship resulting in Mountune supplying race winning engines to customers around the world. In the early '90s, Group A rallying was the pinnacle of its sport and the works Escort Cosworth's were all powered by Mountune-built, 2-liter Ford YB engines.
