Upgrade your Rocky Mountain Cone Filter Intake today with our air box upgrade kit!  For conversions with existing cone style air filters.

RMW performance air intake for your four-cylinder Vanagon/Subaru conversion. Our custom air intake is constructed from 3" polished aluminum tubing with silicone fittings, and the enclosed filter box uses a Subaru stock filter. This will increase airflow to your engine and boost performance.

Choose between 2.2L and 2.5L.  Please check to see whether your EJ25 uses a MAF sensor.  If it does, note the part number on the sensor and order the appropriate upgrade kit.

Don't have an intake yet for your Vanagon 2.5L Subaru conversion?  Get the RMW custom air box complete kit here.

Please Note: There may be fitment issues when used in conjunction with DOHC motors.
