This adapter plate can be used on Mitsubishi style MAF cars such as the Eclipse, Talon, Laser, 3000GT, Dodge Stealth and more! It adapts from the stock MAF to a conical, open-air filter. This adapter eliminates the restrictive factory air box, allowing your car to breath, hence freeing up some extra horsepower! We would highly recommend a K&N open element filter or another quality, reusable, open-air filter with a 4 1/2" opening.
