I was comparing area of OEM paper filters
on different vehicles, which you can do a direct comparison. Do to the size of the OEM paper filter in the 2.3L 4 cylinder, the K&N won't flow any more than the OEM paper filter will flow, just more dirt & oil.

Where do you see this besides on the K&N website?
Here is a truly independent dyno test of a K&N filter on a 3.0L....the K&N
made ABSOLUTELY NO DIFFERENCE!!:
Try to understand this concept:
1) The 2.3L engine will pull 375CFM of air at WOT, and 6000RPM
2) A clean OEM paper filter will flow 600CFM of air
3) A "NEW" K&N filter will 700CFM of air
If both the OEM paper filter, and the K&N filter will flow >>375CFM of air, there will not be an increase with the K&N.
So, save your MAF sensor, IAC valve, throttle body, and your wallet, stay with the OEM paper filter!!
