A turbocharged vehicle is all about airflow in and airflow out. Keeping the turbo running cool and efficient is how you maximize its potential. The Ford Focus ST has a very well developed turbocharger system. To further improve the performance of the Focus, Agency Power has enhanced the lower intercooler pipe with this 2.5-inch diameter pipe upgrade. Utilizing the factory rubber connection at the turbo, the pipe keeps air flowing strongly from the intercooler to the turbo Built as an OEM replacement, the piping can be used with the stock or aftermarket intercooler setups. This intercooler pipe as tested will help the turbo spool up quicker and give you better throttle response. Built from 6061 aluminum, it has been finished in wrinkled black and includes necessary silicone couplers. Other color options are available.
