Surging MAF Readings

Applicable Vehicles:

  • Mitsubushi Evo X (all trim levels)
    • 2008-2015

Surging idle and odd drivability can be caused by having an intake that is not shielded from the cooling fan air. This turbulent air and cause bouncy MAF readings which will throw off fueling and load calculations. If you're running into odd surging issues the easiest way to see if this is an issue is to check and see if the idle issue occurs most often when the fans are coming on.  The COBB SF Airbox for the Evo X will help to prevent hot and turbulent air from being ingested into the engine. A perfect compliment for cars that are already utilizing the COBB Evo X SF Intake.
