The new Process West Street Air Box is now available. Designed to replace the factory restrictive air box and part of the factory intake tract.

The Street air box has the same DNA of the 4" race air box system. Utilising a massive 6" ID K&N filter mounted to a custom spun aluminium trumpet into 4in mandrel bent aluminium piping for maximum flow.

If you want a loud high flowing intake this is system for you. The system is compatible with the stock intercooler piping and all 3 stages of the Process West intercooler systems.
