I have a stillen Air box ,and i am currently using the filter it came with(K&N). I have a JWT pop-charger and i would like to know if that filter would also work with the Stillen box. The reason i would like to use the pop-charger again is because it is louder, and i need to clean one of the filters anyway. Let me know if you have tried this before?

I don't think the base diameter is the same. The Stillen filter has a huge ~6" base.

 

I have heard this works fine... I have the same setup coming this week....

 

For the record it fits, but I do not hear any difference between the two. The Stillen air box must block most of the noise from the filter.

 

It works just fine. No problems, here.

 

I just installed my Stillen Cold Air Box with Popcharger..&...It fits!.... its basically the same filter, same velocity stack.... but the popcharger is open at the head of the filter.... the stillen is capped off- so I figured the popcharger would flow better.... I must say- maybe its the butt_dyno, but I feel a noticeable difference in throttle response with the Stillen/Popcharger over just the drop in K&N panel filter (running the z-tube for both)
