Cold Air/Short Ram Intake
|
|
I'm looking at putting in a cold air intake, or a short ram intake into my 07 CL focus. Has anyone done this previously, that can give me any ideas and opinions on it?
Will it make a noticeable difference on performance and sound? What about fuel economy? Which brand is best?
And probably most importantly, how easy are they to install? Do you need to remove the current air box and replace it with the CAI filter?
Any help would be much appreciated.
Many thanks in advance
