ETS 3.5" MAF Housing | Subaru WRX 2015+
Are you maxing out the factory MAF with your upgraded turbo? If so, this is the upgrade for you! This is the same MAF Housing we use with our turbo kit. Optional couplers are available to adapt to the stock intake or turbo kit intake.
Please Note - A tune will be required to run this MAF housing as the MAF needs to be re-scaled for the larger housing.
