Ali, I thought you had the DDM Intake? The filter might be made by K&N. As far as intakes, there are only three I know of that most consider good:
JCW - Expensive
Dinan - Discontinued
DDM - still available (I thought this was the one Way installed)
The reason that it is important is that though they are all referred to as CAI (cold air intake), some testing has been done over the years and some of the crappier aftermarket intakes were determined to allow engine heat into the intake which pretty much negates the cold aspect, which is what you want for making power.
I'm using the Dinan which was installed about 5 years ago, so I must admit I'm not in tune with all the currently available options that I might not have listed above. Research is good and maybe someone else can chime in if they know of another good intake.
