You will notice a HUGE difference with a K&N air filter...you will ruin your MAF!!! Type in k&n air filter in the search box, you will find all you need to know about it.
Or look at the link on above post.

Heh - we made it all the way to the ninth of the month before a K&N question. That might be a record.
The OP should read this: (and then follow the advice above and return the filter)

Shop elsewhere... It's only $11.70 at Roseland... if you buy a filter kit (which you'll need anyway), shipping's free... http://www3.ns.sympatico.ca/roseland/VWPartsA4.htm

Here's my question...
Is there a quality dry filter that doesn't need replaced basically every year?
I guess I could retrofit one of those flow meters to get the most out of the stock filter.
It is also my understanding that the principle is that the fibers vibrate blocking the dust. Something like a desktop fan where you can see right through but you can't fit anything through.

I guess spending $12 a year is too much...
Considering the stock (Mann, Hengst, whatever) air filters are really good for something like 80,000 miles (depending on the ambient dust conditions), for what you'd spend on the air flow meters, you may just as well just replace with a stock unit every 1-1/2 to 2 years...
BTW: many people feel that the air box should never be opened unless you're replacing the filter, as the seal will have conformed itself to the box and will no longer function as well...

Here you have to define "quality" to answer this question. AEM "DryFlow" filters are probably the best choice (that I know of) and it never has to be replaced (it can be washed) However, you have to realize that most aftermarket filters flow more air because the filter it less effectively. There is no magic in air filter design, the bigger the holes the more air flows through it. However, the bigger the holes the more fine dirt/dust also gets through. Given the same size holes, the larger the surface area the more air it will flow. The stock filter has far more surface area (many pleats) than most aftermarket filters, so it can filter better and still flow enough air to keep your turbocharger happy. Unless you install a really big aftermarket turbo, the stock CAI has more than good enough flow with excellent filtering.
