Doesn't matter if it's a short ram or CAI - anything that changes the airflow in the vicinity of the MAF (mass airflow sensor) will affect tuning in a negative way. Leave it stock unless you plan to spend the bucks for an hour of dyno tuning for little or no gain just to smooth out the torque curve.

MAF mis-readings as explained by BAN SUVS.

This is an alternative method of correcting what the aftermarket intake does to MAF metering posted by EcuTek in the UK.

Josh of Cobb Tuning on aftermarket intakes.

Topic again explained by azscoobie (Clark) and confirmed by Shiv Pathak of Vishnu Performance.

It may be a different story if you're upgrading to a big turbo (bigger than the usual VF30/34 on an EJ20) or a front-mount intercooler which necessitates the use of an aftermarket intake.
