Description
The Mishimoto MMAB-WRX-15 is a purpose-built, powdercoated black steel airbox engineered to complement your existing Mishimoto Performance Air Intake on the 2015-2021 Subaru WRX (non-STI). Made from durable steel and finished in a glossy black powder-coat, this airbox is designed to route more cold outside air directly into your intake system while adding a clean, finished look to the engine bay. Because it helps isolate the intake from underhood heat, it can also provide a more accurate MAF reading in some cases, aiding more reliable datalogging and tuning.
Whether you’re refining a cold air intake setup or completing an air intake system already installed in your WRX, this Mishimoto airbox works alongside your current Mishimoto cold air intake rather than replacing it. By shielding the intake filter from hot engine bay air and channeling cooler outside air toward the intake filter, the airbox helps your cold air intake filter draw in cooler, denser air. It’s a simple bolt-on addition that rounds out your air intake system without requiring you to swap your existing Mishimoto intake piping or filter, and it ships with all the hardware and protective edge stripping needed for a clean install.
Vehicle Applications
This airbox is built specifically for the non-STI Subaru WRX (VA chassis) equipped with the FA20DIT engine, covering model years 2015 through 2021.
