ETS Subaru WRX 2015+ Stock Turbo Intake

This intake feeds the stock-location FA20 WRX turbo through 3-inch stainless tubing, a large filter and velocity stack. I'd use it when inlet flow and more audible turbo sound are part of the build.

The airbox option separates the filter from engine-bay heat; choose oiled cotton or dry synthetic to suit maintenance preference. ETS designed this MAF arrangement for the factory calibration but recommends a pro tune for maximum performance. Have fueling and boost checked for the actual combination. ETS excludes EyeSight-equipped WRXs from this fitment.
