Looking for a little more acceleration and power but don't wana pay for an exspensive K&N intake? Here is a filter I built for my 2002 Subaru Outback Sport (have since upgraded to a WRX). This design has been specifically designed for my car, however not guaranteed to work on all cars. Some vehicles have Air Sensors and will need more work to attach this to the new intake (may cause the "Check Engine" Light to come on).Use at your own risk!
(WARNING: This Instructable is for use on Non-turbocharged vehicles! Turbo vehicles create a vacuum that may cause damage to the filter which could damge the turbo, engine, etc.
