Not much on the performance, maybe on the gas mileage, plus you would hear your dV a lot more if you just put a cone filter at the end of your MAF

OMG GET A SHROOM! 1UP!

no seriously, i think this would be ideal, it's a dryflow filter, no no maf issues.
It also has more airflow than a cone filter.

I like my tt quiet, so I went with a k and n drop in. It's ok... about the same as anything else.

BPI flow stack and AEM dryflow filter. Great for stock and up for a much larger turbo.

I just thought I would bump this to say I'm on my first full tank after K&N and notice a 2-3 mpg [average] improvement on mileage driving same route to work. Agree with Moeron7, don't notice much HP boost.
