Following a few early posts regarding the goodness of the OEM setup:
I got the intake flow rate per RPM per a couple dyno runs. In each case the flat flat part of the curve shows that this is where the OEM setup is limited on how much air it can pull in. Most of the gains (shown from various vendors) occur at this higher RPM range and will vary depending on how well the intake air temperature is managed.
For the sound, for the looks, for a few HPs at higher RPMs getting a "CAI" is really great!
