Best CAI for 2.0 Duratec

I was wondering witch is the best filter quality is not an issue as i already have a 3" K&N air filter.

Was just looking at the fswerks and the CFM one dont want to throw $ by the window i know mainly this is an aluminium or steel pipe but as our d20 and d23 are sensible to air turbulance variation from the maf i want to know your opinion.

Mainly i know the design can make a different sound in the cabin ex: full cai vs short ram.

Well i need advice and is this worth it to buy one with insert that can be removed for a dyno tune? is this really worth it ? i only have for now a magnaflow full exhaust?....

Thanks :)

Once E-Bay gets mentioned I always have to comment that SOME cheap units don't have the right diameter MAF tube & won't work properly.

Measure any replacement carefully before installation to avoid this problem, easier to return when never installed.
