No, not that.

Pop chargers... I've got a K&N - not too big (long or wide). Stillen's are significantly bigger than my K&N. MoDiddy has some type...(dunno if its K&N) but it's real long and real pointy.

Will I notice a differnce from a dyno from say:

K&N vs. Stillen vs. Kool Blue ?

 

I have a K&N filter on my GTI's Pop-Charger and I was suprised how big it was. Its almost the same size of the bottom of the air-box. You could assume that because its bigger it has more access to air.

 

That's what common sense tells me, but then again...I didnt know for sure. Depending on what the filter is made of, yadda yadda yadda...

 

i guess it'll eventually comes down to other parts of the intake system/tract other than the filter itself that'll be the limiting factor. a filter can be huge but the throttle body, for example, will only allow so much air to go through. just my 2 cents
